Basic Safety Instructions

Operating states and operating positions

The product may be operated only under the operating conditions and in the positions specified by the
manufacturer, without the product's ventilation being obstructed. If the manufacturer's specifications are
not observed, this can result in electric shock, fire and/or serious personal injury or death. Applicable local
or national safety regulations and rules for the prevention of accidents must be observed in all work
performed.

1. Unless otherwise specified, the following requirements apply to Rohde & Schwarz products:
predefined operating position is always with the housing floor facing down, IP protection 2X, use only
indoors, max. operating altitude 2000 m above sea level, max. transport altitude 4500 m above sea
level. A tolerance of ±10 % shall apply to the nominal voltage and ±5 % to the nominal frequency,
overvoltage category 2, pollution degree 2.

2. Do not place the product on surfaces, vehicles, cabinets or tables that for reasons of weight or stability
are unsuitable for this purpose. Always follow the manufacturer's installation instructions when
installing the product and fastening it to objects or structures (e.g. walls and shelves). An installation
that is not carried out as described in the product documentation could result in personal injury or
even death.

3. Do not place the product on heat-generating devices such as radiators or fan heaters. The ambient
temperature must not exceed the maximum temperature specified in the product documentation or in
the data sheet. Product overheating can cause electric shock, fire and/or serious personal injury or
even death.

Electrical safety

If the information on electrical safety is not observed either at all or to the extent necessary, electric shock,
fire and/or serious personal injury or death may occur.

1. Prior to switching on the product, always ensure that the nominal voltage setting on the product
matches the nominal voltage of the mains-supply network. If a different voltage is to be set, the power
fuse of the product may have to be changed accordingly.

2. In the case of products of safety class I with movable power cord and connector, operation is
permitted only on sockets with a protective conductor contact and protective conductor.

3. Intentionally breaking the protective conductor either in the feed line or in the product itself is not
permitted. Doing so can result in the danger of an electric shock from the product. If extension cords
or connector strips are implemented, they must be checked on a regular basis to ensure that they are
safe to use.

4. If there is no power switch for disconnecting the product from the mains, or if the power switch is not
suitable for this purpose, use the plug of the connecting cable to disconnect the product from the
mains. In such cases, always ensure that the power plug is easily reachable and accessible at all
times. For example, if the power plug is the disconnecting device, the length of the connecting cable
must not exceed 3 m. Functional or electronic switches are not suitable for providing disconnection
from the AC supply network. If products without power switches are integrated into racks or systems,
the disconnecting device must be provided at the system level.

5. Never use the product if the power cable is damaged. Check the power cables on a regular basis to
ensure that they are in proper operating condition. By taking appropriate safety measures and
carefully laying the power cable, ensure that the cable cannot be damaged and that no one can be
hurt by, for example, tripping over the cable or suffering an electric shock.

1171.0000.42 - 09 Page 3

Basic Safety Instructions

6. The product may be operated only from TN/TT supply networks fuse-protected with max. 16 A (higher
fuse only after consulting with the Rohde & Schwarz group of companies).

7. Do not insert the plug into sockets that are dusty or dirty. Insert the plug firmly and all the way into the
socket provided for this purpose. Otherwise, sparks that result in fire and/or injuries may occur.

8. Do not overload any sockets, extension cords or connector strips; doing so can cause fire or electric
shocks.

9. For measurements in circuits with voltages V

> 30 V, suitable measures (e.g. appropriate

rms

measuring equipment, fuse protection, current limiting, electrical separation, insulation) should be
taken to avoid any hazards.

10. Ensure that the connections with information technology equipment, e.g. PCs or other industrial
computers, comply with the IEC 60950-1 / EN 60950-1 or IEC 61010-1 / EN 61010-1 standards that
apply in each case.

11. Unless expressly permitted, never remove the cover or any part of the housing while the product is in
operation. Doing so will expose circuits and components and can lead to injuries, fire or damage to the
product.

12. If a product is to be permanently installed, the connection between the protective conductor terminal
on site and the product's protective conductor must be made first before any other connection is
made. The product may be installed and connected only by a licensed electrician.

13. For permanently installed equipment without built-in fuses, circuit breakers or similar protective
devices, the supply circuit must be fuse-protected in such a way that anyone who has access to the
product, as well as the product itself, is adequately protected from injury or damage.

14. Use suitable overvoltage protection to ensure that no overvoltage (such as that caused by a bolt of
lightning) can reach the product. Otherwise, the person operating the product will be exposed to the
danger of an electric shock.

15. Any object that is not designed to be placed in the openings of the housing must not be used for this
purpose. Doing so can cause short circuits inside the product and/or electric shocks, fire or injuries.

16. Unless specified otherwise, products are not liquid-proof (see also section "Operating states and
operating positions", item 1). Therefore, the equipment must be protected against penetration by
liquids. If the necessary precautions are not taken, the user may suffer electric shock or the product
itself may be damaged, which can also lead to personal injury.

17. Never use the product under conditions in which condensation has formed or can form in or on the
product, e.g. if the product has been moved from a cold to a warm environment. Penetration by water
increases the risk of electric shock.

18. Prior to cleaning the product, disconnect it completely from the power supply (e.g. AC supply network
or battery). Use a soft, non-linting cloth to clean the product. Never use chemical cleaning agents such
as alcohol, acetone or diluents for cellulose lacquers.

Operation

1. Operating the products requires special training and intense concentration. Make sure that persons
who use the products are physically, mentally and emotionally fit enough to do so; otherwise, injuries
or material damage may occur. It is the responsibility of the employer/operator to select suitable
personnel for operating the products.

1171.0000.42 - 09 Page 4

Basic Safety Instructions

2. Before you move or transport the product, read and observe the section titled "Transport".

3. As with all industrially manufactured goods, the use of substances that induce an allergic reaction
(allergens) such as nickel cannot be generally excluded. If you develop an allergic reaction (such as a
skin rash, frequent sneezing, red eyes or respiratory difficulties) when using a Rohde & Schwarz
product, consult a physician immediately to determine the cause and to prevent health problems or
stress.

4. Before you start processing the product mechanically and/or thermally, or before you take it apart, be
sure to read and pay special attention to the section titled "Waste disposal/Environmental protection",
item 1.

5. Depending on the function, certain products such as RF radio equipment can produce an elevated
level of electromagnetic radiation. Considering that unborn babies require increased protection,
pregnant women must be protected by appropriate measures. Persons with pacemakers may also be
exposed to risks from electromagnetic radiation. The employer/operator must evaluate workplaces
where there is a special risk of exposure to radiation and, if necessary, take measures to avert the
potential danger.

6. Should a fire occur, the product may release hazardous substances (gases, fluids, etc.) that can
cause health problems. Therefore, suitable measures must be taken, e.g. protective masks and
protective clothing must be worn.

7. Laser products are given warning labels that are standardized according to their laser class. Lasers
can cause biological harm due to the properties of their radiation and due to their extremely
concentrated electromagnetic power. If a laser product (e.g. a CD/DVD drive) is integrated into a
Rohde & Schwarz product, absolutely no other settings or functions may be used as described in the
product documentation. The objective is to prevent personal injury (e.g. due to laser beams).

8. EMC classes (in line with EN 55011/CISPR 11, and analogously with EN 55022/CISPR 22,
EN 55032/CISPR 32)

4.1 Manual Operation

The front panel of the R&S FPC1000 provides various types of buttons (or keys) on its
front panel that allow you operate it manually.

Using function keys

Function keys are the group of keys with a light grey background.

Figure 4-1: Function keys

Pressing one of the function keys opens a list of parameters on the display that con­tains settings that thematically belong together. This list of parameters is also referred
to as a menu.

For example, pressing the "Freq" key opens the "Frequency" menu that contains
parameters to configure the frequency characteristics of the measurement.

The contents of the menu depend on the measurement application that you are using.

For example, the "Frequency" menu in the spectrum application looks different than
the "Frequency" menu of the analog demodulation application.

Exceptions are the "Preset" key and the camera key. These do not open a menu, but
initiate an action (performing a preset and taking a screenshot, respectively).

You can modify a specific parameter (menu item) with one of the softkeys.

Using softkeys

Softkeys are the group of keys to the right of the display.

Pressing one of the softkeys allows you to modify the properties of the parameter that
is displayed next to it. The parameter assigned to each softkey is variable and depends
on the function key that you pressed last.

For example, when you press the "Freq" function key in the spectrum application, the
first item in the menu is the "Center Frequency". When you press the softkey next to

18User Manual 1178.4130.02 ─ 02

R&S®FPC1000

Operation

Manual Operation

that menu item, the R&S FPC1000 opens an input field that allows you to change the
center frequency.

Depending on the parameter, pressing a softkey has one of the following effects.

●

It opens an input field that allows you to modify a parameter by entering a specific
value. When an input field is open, the corresponding menu item turns orange.
Example: Pressing the "Freq" key and selecting the "Center Frequency" menu item
opens an input field.

Figure 4-2: Softkey turns orange when an input field is open

Pressing the softkey again, closes the input field. If you have changed the value in
the input field, the new value is adopted.

Figure 4-3: Softkey turns grey when the input field is closed

●

It opens a submenu which contains another list of parameters that thematically
belong together.
A softkey that opens a submenu shows an arrow (">") in its label.
Example: Pressing the "Freq" key opens the "Frequency" menu. The second soft­key in the list ("Center Freq Step Size") opens a submenu.

Figure 4-4: Softkey with an arrow opens a submenu

●

It initiates some kind of action.
Example: Pressing the "Span" key and selecting the "Full Span" menu item
restores the full frequency span.

●

It changes the state of something (like a toggle button).
The corresponding menu item turns light blue when its state is "on".
Example: Pressing the "BW" key and selecting the "RBW: Auto" menu item turns
automatic selection of the resolution bandwidth on and off.

Figure 4-5: Softkey in the "on" (left) and "off" (right) state

●

It opens a dialog box that contains additional settings.
Example: Pressing the "Setup" key and selecting the "Instrument Setup" menu item
opens a dialog box to configure general instrument properties like date and time.

R&S®FPC1000

Operation

Manual Operation

Figure 4-6: Input keys

The input keys only have an effect when any kind of input field is active on the display.

There are several types of input keys.

●

Alphanumeric keys
The alphanumeric keys allow you to enter numeric values or characters: the num­bers from 0 to 9, the alphabet, a minus and plus sign and a dot. Pressing the num­ber 0 repeatedly allows you to enter an empty space and an underscore.
Press the corresponding key to enter a numeric value. In case of numeric values,
each key covers just the number that is printed on it. You can enter negative val­ues with the minus sign key and enter values that contain decimal places with the
dot key.
Example: Press the "Freq" key and select the "Center Frequency" menu item.
Enter a number with the alphanumeric keys.
If you need to enter a character (for example for file names), the key assignment
changes. Each key covers one number and more than one character with the first
choice being a lower case character. If you need to enter a character, press the
key several times until the character you require is selected.
Example: Press the "Freq" key and select the "User Preference" menu item. In the
dialog box, select the "Site Name" menu item and enter some characters (for
"Home", for example, press 6x"4", 3x"6", 1x"6" and 2x"9").

●

Unit keys
The unit keys confirm entries of values that have a unit. The units assigned to each
key are indicated on the key itself or next to the key.
Example: Press the "Freq" key and select the "Center Frequency" menu item. To
define a center frequency of 100 MHz, enter "100" and confirm with the MHZ key.

●

Escape key
The "Esc" key cancels entries and closes the input field. The firmware does not
adopt the entry you have made.

●

Backspace key
The "Backspace" key (

) moves the cursor one position backwards and deletes
the character / number that was in that place.
Tip: If an input field is visible, the backspace key toggles between the last two
entries. Using this feature, you can, for example, quickly toggle between two center
frequencies.

●

"Enter" key ("✓")
The "✓" key confirms an entry you have made.
If you confirm a value that has a unit with the "✓" key, the R&S FPC1000 always
uses the highest possible unit (for example GHz or s).

In addition, the group of input keys also contains cursor keys and the rotary knob.

Using the cursor keys

The cursor keys do several things, depending on the situation when you use them.

●

The cursor keys navigate through dialog boxes.

●

The up and down keys increase or decrease any kind of numeric value if an input
field is active.
The cursor keys change numeric values with a fix step size.

●

The up and down keys move markers around.
The step size is fix.

●

The left and right keys move the cursor in an input field in the corresponding direc­tion.

Using the rotary knob

The rotary knob does several things, depending on the situation when you use it.

●

The rotary knob works like a cursor key in dialog boxes. In that case, you can navi­gate to one of the items with the rotary knob. If the dialog box covers more than
one screen page, it also scrolls through the dialog box.
Turning it to the right corresponds to a downward movement. Moving it to the left to
an upward movement.

●

The rotary knob increases or decreases any kind of numeric value if an input field
is active.
Turning it to the right corresponds to an increase, turning it to the left to a decrease
of a numeric value.
The rotary knob changes numeric values with a fix step size.

●

The rotary knob moves markers around in the diagram area.
To do so, you have to select a marker first. The step size is fix.

●

Pressing the rotary knob has the same effect as pressing the "✓" key and confirms
an entry or selection.

4.2 Screen Layout

The following image shows the screen layout in the spectrum application. It shows all
elements that are the same in all applications of the R&S FPC1000. If an application or
measurement has a completely different layout or elements, the differences are noted

For a comprehensive description of the R&S InstrumentView software, refer to its
user manual.

Tip: Lab display. The lab display allows you to access several instruments at the
same time via the remote desktop. For more information, refer to the documenta­tion of the R&S InstrumentView software.

Remote desktop (R&S MobileView)

R&S MobileView is an app that allows you to remote control the R&S FPC1000 from a
tablet or smartphone. It basically works like the remote desktop application built into
the R&S InstrumentView software.

You can download the app from the Google Play Store (Android based devices) or the
AppStore (iOS devices). A search for "Rohde Schwarz MobileView" should find the
app.

1. Start the R&S FPC1000.

2. Configure your tablet or phone as a hotspot for an ad-hoc connection (usually in
the phone settings).

3. Connect the R&S FPC1000 to the mobile device.

a) Press the "Setup" key to open the instrument setup menu.
b) Select "WiFi": "On" to turn on the Wi-Fi functionality.
c) Select the "Connect" menu item to start a search for Wi-Fi networks in the

area.

devices, routers etc.).
d) Select the network you want to connect to.
e) Enter the password of the network with the alphanumeric keys. The network

password should be displayed in the hotspot settings of the mobile device.

The R&S FPC1000 establishes the connection.

4. Start the R&S MobileView app on your mobile device.

The app shows a list of all R&S FPC1000 devices that are connected to the hot­spot.

5. Select the R&S FPC1000 you want to connect to.

The app shows a live simulation of the R&S FPC1000, including all keys available
on the front panel.

Everything you do in the app is also done on the connected R&S FPC1000.

25User Manual 1178.4130.02 ─ 02

R&S®FPC1000

Operation

Remote Operation

Note: If you have a device that does not support ad-hoc connections, you have to
connect both devices to an existing wireless infrastructure (for example through a
router). When you connect both the mobile device and the R&S FPC1000 to the
infrastructure, you can use the app just like with an ad-hoc connection.

Remote operation (SCPI commands)

Remote operation with SCPI commands is a method to automate measurements by
writing scripts or programs that contain all instructions required for the measurement.
When you start the program, the measurement is done automatically from start to fin­ish. Manual configuration of a measurement with function keys, softkeys or apps is no
longer necessary.

Remote operation is thus a useful tool for measurements that you perform repeatedly
and for which you know the configuration and for which the configuration is always the
same. Testing devices during production is an example for such measurement tasks.
Each device needs to be tested under the same conditions.

You can operate an instrument remotely using SCPI commands (Standard Commands
for Programmable Instruments). Sending a SCPI command initiates one or more
actions on the instrument, for example change the state of a parameter or start a mea­surement. Usually, each parameter available in the firmware has a corresponding
SCPI command.

Example: The SCPI command to change the center frequency is
[SENSe:]FREQuency:CENTer.

When you send a succession of these commands, you can configure and perform
complete measurements.

There are several tools that allow you to connect to an instrument, send an individual
(or more) command(s) and compile automated test sequences.

One of these tools is delivered with the R&S VISA library that is available for download
on the Rohde & Schwarz website (search term: "r&s visa"). The VISA library itself pro­vides input and output functions that are required to communicate with the instrument.

Another tool with more complex scripting functions is R&S Forum, also available for
download on the Rohde & Schwarz website (search term: "forum"). It allows you to run
and edit example script sequences and to write your own script files, as well as on-the­fly remote control of instruments. Script files can range from simple command sequen­ces (Winbatch syntax) to complex programs using the programming language Python.

User documentation and background information is available for both tools. If you want
to learn more about their features, refer to the corresponding user manuals and appli­cation notes.

The following basic introduction to remote control is based on the tool that is delivered
with the R&S VISA.

1. Install R&S VISA on a desktop PC or notebook.

2. Connect the R&S FPC1000 to the computer with a LAN cable or a USB cable.

3. Start the RsVisaTester software (search for "tester" in the start menu). Use the 32­bit or 64-bit version, depending on your operating system.

The user interface of the RsVisaTester opens.

4. Establish a connection to the R&S FPC1000.

a) In the "Resource" field, enter the IP address of the R&S FPC1000 you want to

connect to.
The form is tcpip::<ipaddress>[::protocol][::instrument], you
can leave out the parts in brackets for now. Just enter tcpip::<ipaddress>.

b) Confirm the entry with the "Connect" button.

After a successful connection, you can see in the left pane that the software
already sent the commands necessary to open the connection.

5. Enter a command in the input field in the "Basics" tab, for example *idn? (make
sure to add the question mark). Then select the "Query" button.

The *IDN? (identity) command queries information about the connected product.
In this case, it should return a string similar to this:
Rohde&Schwarz,FPC1000,1328.6660K02/111111,1.00.

"Query" button: whenever you want to retrieve information from the instrument
(query), use this button.

Tip: See Chapter 13.1, "Remote Control Basics", on page 143 for a comprehen-
sive description about the remote command syntax and the ways you can send a
command.

6. For the following command sequence, make sure that the spectrum application is
the active one.
Enter the command instrument:select spec. Then select the "Write" button.

The command selects the spectrum application.

7. At the beginning of a command sequence, you should always preset the instru­ment settings to their default values. You can do a preset with the *RST command.
Enter the command in the input field and select the "Write" button.

button.

8. Enter another command, one that changes an instrument setting, for example
sense:frequency:center 100mhz or the short form freq:cent 100MHZ.
Then select the "Write" button.
The new state of the setting you want to change is defined by a parameter that you
add behind the command.

The SENSe:FREQuency:CENTer command changes the center frequency of the
R&S FPC1000.
After a preset, the center frequency is half of the supported frequency range
(500 MHz for 1 GHz instruments).

When you send the command, the center frequency changes to 100 MHz. You can
observe this change on the instrument display.

9. Send the command again, this time as a query. To query the state of a setting, add
a question mark instead of a parameter (sense:frequency:center?). Then
select the "Query" button.

The command returns the current state of the parameter you have queried (in this
example the return value should be 100 MHz as you have just changed it to that
value).

Remote Operation

Note that unless stated otherwise, a query always returns a numeric value in the SI
derived unit (Hz in case of a frequency, not in kHz, MHz or GHz) and with several
decimal places (usually six).
Commands like SENSe:FREQuency:CENTer work a setting and a query. Other
commands do not work both ways. *IDN, for example, is only allowed as a query
(setting anything is not possible). *RST, for example, is only allowed as a setting (a
query is not possible). Information about how you can use command is included in
the command description.

10. Send a succession of commands to measure the spectrum around the center fre­quency of 100 MHz.

initiate:continuous off

a)

This command selects single sweep mode, recommended for remote measure­ments.

initiate:immediate;*wai

b)

You can write two commands into one command line, but have to separate
them with a semicolon (;). The first command (INITiate:IMMediate) ini­tiates the measurement. The second command (*wai) instructs the program to
wait until the preceding command (INITiate:IMMediate) has been execu­ted before any subsequent commands are sent. This synchronization to the
end of the measurement is important, because it makes sure that the measure­ment is done before taking another action.

11. When the measurement is done, you can query the measurement results (trace
data).
Send the query trace:data? trace1 to do so.

29User Manual 1178.4130.02 ─ 02

R&S®FPC1000

TRACe:DATA is a query, but you have to state a parameter in that case. The
parameter defines which data is returned (in this case, the data of trace 1; you
could also display a second trace whose data you could query with TRACe:DATA
TRACE2).

The trace data contains 1183 level values (one value for each pixel of the display).
The unit of the values is dBm. The values are shown in the message box of the
user interface.

You can copy the trace data from the message box and paste it into a text file,
spreadsheet etc. for further evaluation. (There are also SCPI commands that auto­matically copy that data into a file, so you do not have to do that manually.)

Tip: Logging commands with the . You can save all commands you have sent with
RsVisaTester into a log file (.txt file type) and reuse it later on.
To do so, turn on the "Write Log" feature and select a folder to save the file in
("Change Log File" menu item).

Figure 4-8: Logging feature in the VISA tester application

This was a short example of how to use SCPI commands to measure a signal.
Depending on your measurement task you can expand the succession of com­mands as you like, write it into a script and automate a measurement.

●

Chapter 13.8, "Data Management", on page 170

The R&S FPC1000 provides several tools to manage data related to your measure­ment tasks. Data related to measurements can come in different forms and formats,
like limit lines, channel tables, specific measurement setups, measurement results or
screenshots. All this data is usually stored in a file whose characteristics and file exten­sion depend on the data type. Channel tables, for example, are stored in files with the
extension .chntab while measurement configurations are stored in files with the
extension .set.

Some data types like limit lines, transducer factors or channel tables, should already
be available before you perform a measurement (for example limit lines, transducers or
channel tables). This data is also referred to as templates. Other data types like mea­surement setups or screenshots are only created during the measurement or when the
measurement is done. This data is also referred to as datasets.

Templates and datasets

Templates are measurement or analysis tools that you usually apply to measurement
and that have an effect on the measurement results. A typical template that you might
use regularly is a limit line or transducer factor. The R&S FPC1000 already provides
several predefined templates. If you need to create custom templates, you have to use
the R&S InstrumentView software package.

Templates come in different forms and formats. Each type of template thus has a dif­ferent file extension. Examples: .chntab (channel table), rellim, abslim (relative
and absolute limit lines) or pritrd and sectrd (primary and secondary transducer
factors).

You can load templates into a measurement in the corresponding context menus.

●

Loading limit lines: see Chapter 9.12, "Limit Lines", on page 107.

●

Loading channel tables: see Chapter 9.3.3, "Channel Tables", on page 76.

●

Loading transducer factors: see Chapter 9.4.4, "Transducers", on page 83.

For more information about creating and editing templates, refer to the user manual of
the R&S InstrumentView software package.

Datasets on the other hand are an image of the measurement configuration and result.
Typically, you will only create them during or after the measurement and they include
information if a template is used in the measurement. They are useful, for example, to
recreate the context of the measurement, for documentation purposes or a more
detailed analysis with another tool later on. You can also use a dataset to create a cus-

tom preset state.

R&S®FPC1000

Data Management

Storage devices

You can store all this data on the internal memory of the R&S FPC1000 or on external
storage devices like memory sticks that you can connect to one of the USB ports of the
R&S FPC1000.

The default storage device depends on which devices are connected.

●

If a memory stick is connected, datasets are always stored there first.

●

The internal memory is used only if no memory stick is connected.

Note that the internal memory of the R&S FPC1000 is limited to several Mbytes.
Therefore it is recommended that you use an external memory device like a USB stick
to save measurement data or screenshots and only keep templates and datasets that
you require regularly on the internal memory.

If you use an external storage device, the available disk space is limited only by the
size of the storage device.

Free space of the internal memory

You can find out the disk space that is left on the internal memory of the
R&S FPC1000 in the file manager.

Open the file manager ("Save Recall" > "File Manager"). The free disk space is indica­ted at the top of the dialog box.

Folder structure of the internal memory

The internal memory has a given folder structure. Basically, each data type has its own
designated folder.

For example, there is a folder labeled \Channel Tables that contains all channel
tables that are delivered with the firmware. Another folder is labeled \Datasets that is
the default folder for saving a dataset.

Of course, you can save a dataset in the \Limit Lines folder, but for a good file
organization, it is recommended not to mix up file types.

Using in the file manager

The file manager is a tool that provides functionality to manage the files in the internal
memory or on external storage devices.

1. Press the "Save Recall" key to open the file menu.

2. Select the "File Manager" menu item to open the file manager.

8 Measurement Wizard

Measurement Wizard

The measurement wizard is a tool that allows you to combine several individual mea­surement configurations to a sequence of measurements (or measurement set). Each
individual measurement configuration is based on a dataset that you have previously
saved. Because all relevant parameters have been defined before the actual measure­ment and cannot be changed once the measurement procedure has begun, the wizard
is a good way to avoid mistakes and save time when setting up measurements.

This topic describes the functionality of the measurement wizard. For details on the
individual measurements you can perform with the wizard, refer to the corresponding
chapters.

●

Chapter 10, "The Receiver Application", on page 111

●

Chapter 11, "Analog Demodulation", on page 122

●

Chapter 12, "Digital Demodulation", on page 133

You can use the wizard for measurements in all available applications.

Note that it is necessary to install and use the R&S InstrumentView software package if
you want to access and use the measurement wizard.

Before you can use the measurement wizard, you have to define a measurement set
with the R&S InstrumentView software package and transfer it to the R&S FPC1000.

The R&S InstrumentView software package is available for download on the
R&S FPC1000 website at http://www.rohde-schwarz.com/product/fpc1000.

Creating a measurement set

A measurement set consists of several datasets. A dataset is a file that contains the
settings of a specific R&S FPC1000 configuration, for example frequency, scaling etc.
To get hold of a dataset, set up the R&S FPC1000 as you need and save the configu­ration or use one of the predefined datasets.

For more information about how to create measurement sets, see "Saving datasets"
on page 41.

1. Start the R&S InstrumentView software on your PC.

2. Open the "Wizard Set" editor in the software ("Preparation" > "Wizard Sets").

6. Start the measurement sequence with the "Start Measurement" menu item.

The R&S FPC1000 starts to go through the measurements that are part of the
measurement set. The sequence of the measurement is as defined with the
R&S InstrumentView software.
Note that it is not possible to change any measurement parameters while using the
measurement wizard. Marker functionality and scaling parameters are, however,
available.
Before each measurement, the wizard shows a message box that contains the

instructions for that measurement.

Figure 8-5: Prepare the measurement as described when this message shows up

7. Prepare the measurements as instructed. When you are done, you can start the
measurement.

8. You have several options before you start a measurement.

● "Continue"

Finishes the current measurement and begins with the next measurement by
showing the necessary preparations.

● "Repeat Measurement"

Repeats the current measurement. Repeating a measurement can be useful,
for example, if the results do not match your expectations and you want to vali­date the results.

● "Interrupt"

Interrupts the sequence of measurements. Interrupting a measurement can
become necessary if the measurement does not yield the expected results (for
example violated limit lines).
In that case, you can interrupt the measurement sequence and try to find the
origin of the problem by using different settings or measurements than those
defined in the wizard.
When you interrupt the wizard sequence, the complete functionality is available
as if you would not use the wizard. Results of finished measurements remain in
the memory.
When you are finished reconfiguring the measurement, enter the measurement
wizard and resume the measurement sequence with the "Resume Sequence"
menu item.

● "Skip"

Skips a single measurement and initiates the subsequent measurement.
Skipping individual measurements is possible when you turn on "Allow to skip
measurements and finish wizard sequence" in the "Wizard Set" editor of the
R&S InstrumentView software.

● "Finish Wizard"

Ends the measurement sequence. The results of finished measurements
remain in the memory.

Ending a measurement sequence is possible when you turn on "Allow to skip
measurements and finish wizard sequence" in the "Wizard Set" editor of the
R&S InstrumentView software.

● "Cancel"

Aborts the measurement sequence. The results of finished measurements are
lost.

When all measurements of the sequence are done, the R&S FPC1000 shows a
corresponding message.

Figure 8-6: On screen information that all measurements are done

When you have finished all measurements that are part of the measurement
sequence, the R&S FPC1000 asks you if you want to save the measurement
results.

9. Select the "Save Result" menu item to save the results.
If you do not want to keep the results, you can discard the results with the "Discard
Result" menu item.

Tip: Limited internal memory. If you have to store the results on the internal mem­ory, make sure that it has enough space left to store them. Else the results might
get lost. If the space is not enough, you can delete old data with the file manager.
For more information, see "Using in the file manager" on page 40.

The results for a measurement set consist of several files, each file corresponding
to one of the measurements. For easy evaluation, the R&S FPC1000 includes the
name of the measurement as defined in the wizard dialog or R&S InstrumentView
in the file name.
All result files that belong to a measurement set are stored in the same directory.
The directory is named after the measurement name and site. The syntax is 'site­name_measurement_#'
The R&S FPC1000 adds numbers in ascending order to files as well as directories
if you perform a measurement or measurement set more than once.

Evaluating results

The R&S InstrumentView software provides functionality to evaluate results and com­pile measurement reports. However, before you can start to evaluate the results you
have to download the results to your computer.

1. Open the "File Transfer" dialog box in the R&S InstrumentView software ("Instru­ment" > "File Transfer").

2. Select the "Wizard Sets" folder on both the R&S FPC1000 (left pane) and the PC
(right pane).

3. Select the measurement set you would like to transfer.

4. Transfer the file to the R&S FPC1000 with the ">>" button.

9.2 Measurements and Result Displays

The R&S FPC1000 allows you to measure a signal in the frequency domain or the time
domain.

You can also equip the R&S FPC1000 with optional extended measurement functions
like ACLR or OBW measurements. These measurements provide settings and tools for
special measurement tasks.

Measuring basic spectrum characteristics

Basic spectrum measurements require no optional equipment on the R&S FPC1000.

1. Connect a DUT to the RF input of the R&S FPC1000.

2. Turn on the R&S FPC1000.

The R&S FPC1000 measures the characteristics of the DUT in the frequency
domain with the default configuration. It shows the results as a line trace in the dia­gram shown on the display.

Frequency domain measurements

In the frequency domain, the R&S FPC1000 analyzes the input signal characteristics
over a certain frequency span. You can use it, for example, to obtain basic measure­ment results like peak levels and the shape of the spectrum.

The horizontal axis shows the frequency, the vertical axis shows the signal levels.

The measurement in the frequency domain is the default measurement mode.

Time domain measurements

In the time domain, the R&S FPC1000 analyzes the characteristics of a signal at a par­ticular frequency over time. The span during time domain measurements is 0 (zero

span mode). You can use time domain measurements, for example to monitor the

characteristics of a signal and its behavior over time.

The horizontal axis shows the time, the vertical axis shows the signal levels.

You have to select the zero span mode deliberately to measure signal characteristics
in the time domain.

Chapter 13.10.1, "Measurements and Result Displays", on page 179

Available with the optional "Advanced Measurements" application.

The channel power measurement selectively measures the power of modulated sig­nals. Unlike a power meter that performs measurements over its entire frequency
range, the channel power measurement measures the power of a specific transmission
channel. Other signals in the frequency spectrum don't show in the results.

When measuring the spectrum within a channel, the R&S FPC1000 uses a resolution
bandwidth that is small compared to the channel bandwidth. It then determines the
total power of the channel by integrating the results on the trace.

That means that you can compare the result to the result that would have been
obtained from a thermal power meter. The small resolution bandwidth acts like a nar­row channel filter and so prevents out-of-channel emissions from affecting the result.

Selecting the channel power measurement

1. Press the "Meas" key to open the measurement menu.

2. Select the "Measurement Mode" menu item to select the measurement.

3. Select the "Channel Power" menu item.

Define a sufficient span.

The span is always coupled to the channel bandwidth (span = 1.2 to 5 x channel band­width, depending on the channel bandwidth). When you change the channel band­width, the R&S FPC1000 automatically adjusts the span, but not the other way around.

9.2.1.2 Configuration

Access: "Meas"

The channel bandwidth measurement supports several settings exclusive to that mea­surement. These are available in the measurement menu.

Defining the channel bandwidth

The channel bandwidth is the bandwidth of the signal that you are measuring.

Note that the channel bandwidth and frequency span are coupled. When you select a
channel bandwidth, the R&S FPC1000 automatically defines an appropriate span for
the channel bandwidth you have defined (span = 1.2 x channel bandwidth). This mech­anism ensures correct channel power measurements.

1. Press the "Meas" key to open the measurement menu.

2. Select the "Chan Bandwidth" menu item.

The R&S FPC1000 opens an input field to define the channel bandwidth.

3. Enter the channel bandwidth you need.

Note: The minimum channel bandwidth that you can set is 833 Hz at a span of
1 kHz.

Measuring the maximum channel power

If signal levels fluctuate significantly, you can measure the maximum channel power
with the max hold function.

1. Press the "Meas" key to open the measurement menu.

2. Select the "Power Display" menu item.

3. Select the "Max Hold" menu item.

The displayed result shows the highest channel power that has been measured
(indicated by the "Max Power" result in the diagram header.

4. You can return to the normal power display by selecting the "Clear / Write" menu
item instead.

Measuring the channel power density

By default, the R&S FPC1000 the channel power result corresponds to the complete
channel bandwidth you have selected. You can also display the channel power that
corresponds to a bandwidth of 1 Hz. In that case, the results are no longer displayed in
dBm, but in dBm/Hz.

The displayed result shows the channel power measured in a bandwidth of 1 Hz
(indicated by the different unit in the channel power result in the diagram header).

4. You can return to the normal power display by selecting the "Channel Power / Hz"
menu item again.

Selecting the unit for power display

The R&S FPC1000 can apply different units to the power output.

1. Press the "Meas" key to open the measurement menu.

2. Select the "Power Unit" menu item to open the power unit menu.

3. Select the unit you want.

The R&S FPC1000 displays the signal level in the selected unit.

Note: The default unit is dBm.

Selecting a standard

You can store the main measurement settings as a standard file. When you load such
a standard file, the R&S FPC1000 automatically configures the measurement regard­ing channel and general measurement settings.

Standard files for common telecommunications standards are already provided with
the R&S FPC1000 firmware.

If you want to measure a different standard, you can also create custom standard defi­nition files with the R&S InstrumentView software and transfer them to the
R&S FPC1000. For more information, refer to the documentation of the R&S Instru­mentView.

1. Press the "Meas" key to open the measurement menu.

2. Select the "Standard" menu item.

The R&S FPC1000 opens a dialog box to select the standard.

3. Select one of the available standards.

The R&S FPC1000 loads the configuration of the selected standard. It automati­cally sets the span, resolution bandwidth, video bandwidth, sweep time and detec­tor required by the standard.
If the measurement is not according to the selected standard anymore (for exam­ple if you change a parameter), the R&S FPC1000 shows a blue dot in front of the
standard display.

Defining the reference level

The reference level is the power level that the R&S FPC1000 expects at the RF input.
When you select the reference level, make sure that you do not overload the
R&S FPC1000 by applying a signal whose power exceeds the maximum reference
level.

As the power is measured with a small resolution bandwidth compared to the signal
bandwidth, it is still possible to overload the R&S FPC1000, even if the trace is within
the measurement diagram. To prevent an overload, measure the occupied bandwidth
with the largest resolution bandwidth possible using the peak detector. If you set these
parameters, it is not possible for the trace to exceed the reference level.

To simplify operation and to prevent incorrect measurements, the R&S FPC1000 has
an automatic routine for setting the reference level.

1. Press the "Meas" key to open the measurement menu.

2. Select the "Level Adjust" menu item.

The R&S FPC1000 performs a measurement to determine the optimal reference
level.
It uses a resolution bandwidth of 1 MHz, a video bandwidth of 1 MHz and the peak
detector. After finishing the automatic measurement, the R&S FPC1000 sets the
optimal reference level.

Changing the span

Usually, the span that the R&S FPC1000 selects yields optimal results. But sometimes
you also need to see the spectrum outside the current span to detect other signal com­ponents that you need to include in the measurement. Therefore, you can adjust the
span to up to ten times the channel bandwidth and hence still be able to see the spec­trum outside the measurement channel.

1. Press the "Span" key to open the span menu.

2. Select the "Manual Span" menu item.

The R&S FPC1000 opens an input field to define the span.

3. Enter the span you need.

Note: The largest possible span for the channel power measurement is ten times
the channel bandwidth. At larger spans, the result of the channel power measure­ment would be increasingly imprecise, because too few points of the trace would
be in the channel you are measuring.

Measurements and Result Displays

An important characteristic of a modulated signal is its occupied bandwidth (OBW). In
a radio communications system, for example, the occupied bandwidth must be limited
to enable distortion-free transmission in adjacent channels. The occupied bandwidth is
defined as the bandwidth containing a defined percentage of the total transmitted
power.

You can define a percentage between 10 % and 99 %. Numerous standards require an
occupied bandwidth of 99 %.

After entering the channel bandwidth, the R&S FPC1000 automatically selects the
measurement parameters so that you can attain the best result.

occupied bandwidth.

●

Define the correct channel bandwidth.
Only the signal to be measured should be visible in the diagram. An additional sig­nal would falsify the measurement.

●

Define a sufficient resolution bandwidth.
The resolution bandwidth should be between 1 % and 4 % of the channel band­width. This ensures that the occupied bandwidth is measured with high accuracy.

●

Define a sufficient video bandwidth.

The video bandwidth must be at least three times the resolution bandwidth. This
prevents incorrect results due to the compression of signal peaks by the video fil­ter.

●

Select the RMS detector.This ensures that the power measurement is always cor­rect irrespective of the waveform being investigated.
Some of the measurement specifications (for example PDC, RCR STD-27B)
require measurement of the occupied bandwidth with a peak detector. The detector
setting has to be changed accordingly in those cases.

●

Select a sufficient sweep time.

9.2.2.2 Configuration

Access: "Meas"

The occupied bandwidth measurement supports several settings exclusive to that
measurement. These are available in the measurement menu.

Defining the percentage of the occupied bandwidth

The default power percentage to be evaluated inside the occupied bandwidth is 99 %,
a value most standards require. If your measurement requires a different power per­centage, you can change that value.

1. Press the "Meas" key to open the measurement menu.

2. Select the "% Power Bandwidth" menu item.

The R&S FPC1000 opens an input field to define the power percentage.

3. Enter the power percentage the measurement requires.

The R&S FPC1000 now displays the occupied bandwidth graphically in the trace
window and numerically above the trace window.

Note: The value you enter here is the power percentage that has to be inside the
channel bandwidth relative to the power over the total span (the percentage of the
total power).

Defining the channel bandwidth

The channel bandwidth is the bandwidth of the signal that you are measuring.

Note that the R&S FPC1000 always selects a frequency span that equals the channel
bandwidth

Available with the optional "Advanced Measurements" application.

The spectrogram result display shows the spectral density of a signal in the frequency
domain and over time simultaneously.

Like other result displays, the x-axis represents the frequency span. The y-axis repre­sents time. Time in the spectrogram runs chronologically from top to bottom. There­fore, the top of the diagram is the present. A third dimension shows the amplitude for
each frequency by mapping different colors to every power level.

The color the R&S FPC1000 assigns to a power level that was measured depends on:

●

The color table you have selected.

●

The spectrogram reference level.

●

The spectrogram level range.

The spectrogram consists of horizontal lines, each one pixel high, that are called
frames. In the default state, a frame is added to the spectrogram after each sweep.
This means that the amount of data in a frame depends on the sweep time. Because
the spectrogram in the R&S FPC1000 runs from top to bottom, the outdated time
line(s) move down one position, so that the present frame is always on top of the dia­gram. Therefore, the sequence of frames is chronological.

frames are deleted. As the height of the display is smaller than 1024 pixels, some of
the data becomes invisible after a time (but remains in the memory).

display is still updated continuously. If you want to stop the measurement com­pletely, you have to stop it by selecting single sweep mode. In that case, the
R&S FPC1000 finishes the current sweep and stops the measurement. It keeps
the spectrogram data that has already been recorded.

3. Select the "Hold" menu item again.

The R&S FPC1000 resumes updating the spectrogram.
The spectrogram result display is filled with new lines until you change a measure­ment setting.

When you change a setting (for example the center frequency), the spectrogram
clears and starts to fill again.

4. You can also clear the spectrogram manually. Press the "Meas" key.

5. Select the "Clear" menu item.

Resetting the spectrogram

The R&S FPC1000 clears the spectrogram result display when you change a mea­surement setting, for example one of the frequency settings or the resolution band­width.

You can also clear it deliberately.

1. Press the "Meas" key to open the measurement menu.

2. Select the "Clear" menu item.

The R&S FPC1000 deletes the current spectrogram data and starts a new record­ing.

Displaying the spectrogram in full screen

By default, the spectrogram takes half of the diagram area, with the upper part showing
the results of the current sweep as a line trace. You can view more of the signal history
by displaying the spectrogram in full screen mode.

1. Press the "Meas" key to open the measurement menu.

2. Select the "Full Screen" menu item.

The R&S FPC1000 now uses the full diagram area of the screen for the spectro­gram. The number of lines in the spectrogram and therefore the displayed time
period more than doubles.

Note: It can, however, be necessary that the spectrum result display is still visible
to evaluate measurement results. For this purpose, the spectrogram has an (invisi­ble) scrollbar that you can use to scroll up and down the spectrogram to the frame
that you would like to see.

Scrolling through the spectrogram

As more and more lines are added to the spectrogram, older data is moved down until
it disappears from the visible spectrogram. The data itself is still available, but you
have to scroll through the spectrogram to see those parts of the spectrogram.

Arrows on the right side of the spectrogram indicate that more data than is visible on
the screen is available.

► Press the "Up" or "Down" cursor keys.

The R&S FPC1000 scrolls through the spectrogram history.

The symbols on the right side of the spectrogram indicate the position of the spec­trogram part currently displayed on the screen.

● A single down arrow in the right lower corner of the spectrogram indicates that

the uppermost frame still represents the most recently recorded trace.

9.2.3.2 Color Definition

Colors are an important element of the spectrogram. The R&S FPC1000 provides vari­ous features to customize the display for the best viewing results.

Selecting a color scheme

The first and most obvious way to adjust colors is to select a different color scheme.

1. Press the "Meas" key to open the measurement menu.

2. Select the "Settings" menu item to open the spectrogram settings menu.

3. Select the "Color Table" menu item to open the color table menu.

4. Select the color scheme you are most comfortable with.
The R&S FPC1000 adjusts the screen colors according to your selection.

The following color schemes are available.

● Default

● Green-Yellow

● Green-Blue

● Black-White

● Red-Purple

● Blue-Black

Adjusting the color distribution

It is possible that the color distribution is not ideal in the default configuration. The
R&S FPC1000 provides several settings to further enhance the color display in the
spectrogram.

The following examples are based on the red-purple color scheme.

The first method is to cut the reference level. It eliminates amplitudes from the color
map that are not part of the signal.

Example: By default, the spectrogram reference level is -20 dBm.

That means that signal parts with an amplitude of -20 dBm would be red in the spectro­gram, and signal parts with a very small amplitude would be purple. Everything in
between is a shade of the colors between. As the colors are distributed over a very
large range (about a 100 dBm or more), it is likely that you cannot distinguish details in
the signal.

66User Manual 1178.4130.02 ─ 02

R&S®FPC1000

The Spectrum Application

Measurements and Result Displays

Therefore you can adjust the color map to the overall shape of the signal you are mea­suring. Let us say, for example, that the signal has an amplitude range of about 30 dB
with the maximum amplitude at about -80 dBm and the minimum amplitude at about

-120 dBm. With the default settings, the spectrogram is made up exclusively of red col-

ors and it is not easy to distinguish amplitude levels. That is because the purple color
shades are completely out of range.

To get a better result, change the spectrogram reference level to a level near the maxi­mum power level that has been measured first.

1. Press the "Meas" key to open the measurement menu.

2. Select the "Level Range" menu item to open the level range menu.

3. Select the "Reference Level" menu item.

The R&S FPC1000 opens an input field to enter the spectrogram reference level.
The reference level should be near the maximum level that has been measured
while the spectrogram was running. In the example, the reference level should be
at about -80 dBm.

4. Enter the reference level you need.

The R&S FPC1000 now shifts the reference level of the spectrogram to the value
you have entered.
Note that the spectrogram reference level does not affect the reference level of the
spectrum analyzer itself. In the same way, the reference level of the spectrum ana­lyzer does not affect the spectrogram. The spectrum trace therefore remains
exactly the same.

67User Manual 1178.4130.02 ─ 02

R&S®FPC1000

The Spectrum Application

Measurements and Result Displays

The changes however, still do not show signal differences in detail. The only thing
that happened is that the colors have shifted, in the example to purple, because
the color that corresponds to the reference level has shifted from red to purple. All
other colors that are part of the color scheme are still unused, because the spectro­gram level range is still the same (100 dB).

5. Select the "Level Range" menu item.

The R&S FPC1000 opens an input field to enter the spectrogram level range.
In the example, the level range of the signal is from about -80 dBm to about

-120 dBm.

6. Therefore, set the level range to 40 dB to cover the complete level range of the sig­nal.

As the level range is now adjusted, the R&S FPC1000 is able to map its complete
color range to the level range of the signal.
This means that signal parts with a low amplitude are in a shade of red while signal
parts with a high amplitude are purple.

68User Manual 1178.4130.02 ─ 02

R&S®FPC1000

The Spectrum Application

Measurements and Result Displays

The best way to display a spectrogram is therefore to reduce the level range until
the lowest signal part is mapped to the lower end of the color map and the highest
signal part to the upper end of the color map.
Note: You can also use the "Auto Range" menu item to adjust the displayed level
range. In that case, the R&S FPC1000 selects a level range that best suits the cur­rently measured signal.
In a last step, you can configure the spectrogram in a way that it only shows signal
peaks in color and the noise floor in black. To get a result like that you have to
reduce the level range, until the noise floor is outside the displayed range.

7. Instead of entering a level range of 40 dB, enter a level range of 30 dB or even
25 dB.

This provides a high contrast between signal parts that are above the noise floor,
and the noise floor, which is drawn in black.
To show details of the noise floor, and exclude the peak levels you have to lower
the spectrogram reference level, until it is just above the noise floor.
The R&S FPC1000 then displays the signal parts that are above the reference
level in only one color, which is the color at the upper border of the color map.

9.2.3.3 Spectrogram Playback

Saving spectrogram data

You can save the data of the spectrogram for documentation or for further analysis of
the recorded data.

1. Press the "Meas" key to open the measurement menu.

2. Select the "Save" menu item to open the file manager.

3. Enter the name of the spectrogram with the alphanumeric keys.

By default, the R&S FPC1000 saves the spectrogram as Spectrogram### with
ascending numbers. The file extension for spectrogram data is *.spm.

4. Select the "Save" softkey to store the spectrogram.

Now that you have saved the spectrogram, you can replay it any time you want.
The number of spectrograms that you can store on the R&S FPC1000 internal
memory depends on the other datasets that are currently on the R&S FPC1000.

Playback of a spectrogram

If you have recorded a spectrogram and have saved it in internal memory or a memory
stick, you can view the results of that measurement later.

1. Press the "Meas" key to open the measurement menu.

2. Select the "Measurement Mode" menu item.

3. Select the "Spectrogram Playback" menu item.

The R&S FPC1000 enters the spectrogram playback mode. In playback mode, it
no longer records any data. Only the data that has been recorded already is dis­played.

Restoring a spectrogram

You can restore a spectrogram that you recorded some other time and saved in the
internal memory of the R&S FPC1000 or on a memory stick.

1. Press the "Meas" key to open the measurement menu.

2. Select the "Recall" menu item.

The R&S FPC1000 opens the file manager.

3. Select the file you need. The file extension for spectrogram data is *.spm.

The R&S FPC1000 loads the spectrogram and shows the data in the display.
Basically, you can do the same things in spectrogram playback mode as in the
spectrogram recording mode, for example customize the display to your needs.

In addition to that functionality, it is possible to view not only the spectrum that
belongs to the currently selected spectrogram frame, but also the spectrums of all
frames that have been recorded.

Working with time lines in playback mode

To find a particular point in time and display the corresponding spectrum, you can use
two time lines.

When you enter the playback mode, the R&S FPC1000 displays two time lines in the
spectrogram.

Both time lines (T1 and T2) correspond to an absolute time value, whose position
refers to the most recent time frame (top of the diagram). Both time lines are positioned
on the most recent spectrogram line at the top of the result display.

You can now select a specific spectrogram frame that is in the memory of the
R&S FPC1000.

1. Press the "Meas" key to open the measurement menu.

2. Select the "Time Line <x>" menu item.

The R&S FPC1000 opens an input field to define the position of the corresponding
time line (T1 or T2).

3. Position the time line by entering a number or moving it with the rotary knob.

Entering 0 sets the time line marker on the most recent frame. The maximum value
that you can enter is 1024 (the maximum number of frames the R&S FPC1000 can
store in its memory).

Figure 9-4: Time lines in the spectrogram

Note that not all frames are visible on the screen. If a frame is part of the history
outside the visible area, the time line is also not visible and you have to scroll
through the spectrogram to be able to see it again.
The upper window displays the spectrum of the frame at the time line position. By
moving the time line, you can thus browse through the history of spectra stored in
memory.
In the marker information field, the R&S FPC1000 shows the time stamp of the
time line.
The time stamp of the first time line T1 is always referred to the top-most frame. A
time stamp of 00:00:50:000, for example, means that the data was measured
50 seconds prior to the topmost frame).
In addition to the time line (horizontal marker), you can also use (vertical) markers
in the spectrogram.
With the help of the marker and the time line, you are able to find the exact
moment when a specific event has occurred in the spectrum.

4. Press the "Marker" key.

The R&S FPC1000 activates a marker and sets it on the peak level of the currently
displayed spectrum.

5. Use the rotary knob or the cursor keys to move the marker on the x-axis to the fre­quency you want to analyze, or enter the frequency directly with the number keys.

6. Select the "Time Line" softkey and browse through the spectrums using the rotary
knob or the cursor keys until the spectrum of interest is displayed in the upper win­dow.

The time stamp of the selected time line (displayed in a field above the diagram
area) gives you a precise indication on when the event shown in the spectrum
occurred.

Chapter 13.10.2, "Frequency", on page 185

The main application of a spectrum analyzer is to measure the frequency and the
power level of a signal and show these signal characteristics in a diagram. The x-axis
of the diagram usually contains the frequency information of the signal, while the y-axis
usually contains the level information.

Regarding the frequency information, a typical measurement task does not require you
to measure the characteristics of the complete frequency range supported by the
R&S FPC1000. Instead, it is usually sufficient to measure the characteristics of a limi­ted frequency range only.

The R&S FPC1000 provides several settings to control the frequency range it actually
measures.

You can define the frequency range in various ways.

●

In terms of a center frequency and the span around it.

9.3.1 Measurement Frequency

The measurement frequency (or center frequency) is the frequency that the spectrum
analyzer tunes to. It is represented by the frequency at the center of the x-axis in the
diagram area.

If you know the (approximate) frequency of the signal you are measuring, you can sim­ply match the frequency of the DUT to the center frequency and define an appropriate

span.

If you are measuring unknown signals within a greater frequency range, for example
harmonics, it is better to define the frequency range based on start and stop frequen-

cies.

Defining a center frequency

1. Press the "Freq" key to open the frequency menu.

2. Select the "Center Freq" menu item.

The R&S FPC1000 opens an input field to define the center frequency.

Tip: When you press the "Freq" key, the R&S FPC1000 automatically opens an
input field to define the center frequency. If the input field is inactive, you can open
it with the "Center Freq" menu item.

3. Enter the required frequency.

The frequency you have entered becomes the new center frequency.

While adjusting the center frequency, you can obtain a value that is outside the
R&S FPC1000 maximum span. If this happens, the R&S FPC1000 automatically
reduces the span.
You can also define the frequency by selecting a specific transmission channel. In
that case, the frequency is defined in a channel table. For more information, see

"Working with channel tables" on page 76.

Defining a frequency step size

You can change the center frequency in fixed steps easily with the rotary knob or the
cursor keys.

73User Manual 1178.4130.02 ─ 02

R&S®FPC1000

The Spectrum Application

Frequency Configuration

When you select the center frequency with the rotary knob or the cursor keys, the dis­tance of each step that you take depends on the span. With the rotary knob, the small­est possible step is a pixel. With the cursor keys, the step is 10 % of the span or one
division of the grid.

1. Press the "Freq" key to open the frequency menu.

2. Select the "CF Step Size" menu item to open the frequency step size menu.

3. Select one of step size options.

● "0.1 x Span"

The step size equals 10 % of the span or 1 division of the horizontal axis.

● "= Center"

The step size equals the center frequency.
This step size is ideal for measurements on harmonics. When you increase or
decrease the center frequency, the center frequency automatically moves to
the next harmonic.

● "Manual <x> Hz"

Define any step size you want.
This step size makes it easy to investigate a spectrum with frequencies at con­stant intervals.

The R&S FPC1000 adjusts the step size accordingly.

If you set the step size to 10 % of the span or to the center frequency, the
R&S FPC1000 sets the step size internally. Manually defining the step size opens
an input field to define the step size.

Defining a frequency offset

A frequency offset allows you to shift the displayed frequency values by a certain
amount to a higher or lower frequency. This shift is an arithmetical operation only - the
measured frequency really remains the same.

Shifting the frequency to another value can be useful, for example, on frequency con­verting DUTs such as satellite downconverters. You are then able to display the origi­nal, unconverted input frequency of the DUT in the measurement results.

1. Press the "Freq" key to open the frequency menu.

2. Select the "Freq Offset" menu item.

The R&S FPC1000 opens an input field to define the frequency offset.

3. Enter the required frequency offset.

TheR&S FPC1000 adds the frequency offset to the center frequency you have
defined.
A blue dot at the center frequency label indicates that a frequency offset is active.

You can define positive frequency offsets in the range from 1 Hz to 100 GHz in
steps of 1 Hz. The maximum negative frequency offset depends on the start fre­quency you have defined. The start frequency, taking the frequency offset into
account, is always ≥ 0 Hz.

9.3.2 Frequency Span

The span is the frequency range that the measurement covers. You can measure the
full frequency range of the R&S FPC1000, or a smaller part of it. The span also defines
which frequency information is displayed in the measurement diagram - the span is the
frequency range around the center frequency that you have defined.

The available span for frequency domain measurements depends on the instrument
model.

The span you should select depends on the bandwidth of the signal you are measuring
and the type of measurement that you perform. A rule of thumb is to select a span that
is at least twice as large as the bandwidth occupied by the measured signal.

You can define the span directly or in terms of a start and stop frequency.

Defining the frequency span

1. Press the "Freq" key to open the frequency menu.

2. Select the "Manual Span" menu item.

The R&S FPC1000 opens an input field to define the span.

Tip: When you press the "Span" key, the R&S FPC1000 automatically opens an
input field to define the span. If the input field is inactive, you can open it with the
"Manual Span" menu item.

3. Enter a span.

The R&S FPC1000 adjusts the span of the horizontal axis to the value you have
entered.

Tip: If you define a span of 0 Hz (zero span), the R&S FPC1000 measures in the
time domain.
In that state, the R&S FPC1000 measures the signal at the current center fre­quency only. Instead of displaying the spectrum, the R&S FPC1000 shows the sig­nal power over a certain time period (like an oscilloscope). The horizontal axis
becomes the time axis. The display always starts at 0 s and stops after the current
sweep time.

You can select time domain measurements without having to enter the value man­ually. Instead, select the "Zero Span" menu item to get a span of 0 Hz.

Full span measurements

You can restore the span that covers the complete frequency range supported by the
R&S FPC1000 quickly and without having to enter the value manually with the "Full
Span" menu item.

If you need to switch back to a smaller span, you can restore the span that was last
selected with the "Last Span" menu item.

Defining a start and stop frequency

Defining a start a stop frequency is best suited for example for measurements on har­monics or signals whose exact frequency is unknown. When you define a start and
stop frequency, the center frequency is automatically adjusted to be in the center of
start and stop frequency.

1. Press the "Freq" key to open the frequency menu.

2. Select the "Start Freq" menu item.

The R&S FPC1000 opens an input field to define the start frequency.

3. Enter a start frequency.

4. Select the "Stop Freq" menu item.

The R&S FPC1000 opens an input field to define the stop frequency.

5. Enter a stop frequency.

Tip: If you have entered a stop frequency that is outside the maximum frequency
range, the R&S FPC1000 sets the stop frequency to the possible maximum.

The R&S FPC1000 adjusts the horizontal axis according to your input, beginning
with the start frequency and ending with the stop frequency.
The label of the horizontal axis changes from "Center" and "Span" to "Start" and
"Stop".

9.3.3 Channel Tables

Working with channel tables

Almost all transmission systems divide their assigned frequency ranges into channels.
Each channel corresponds to a specific frequency. To keep the handling of such sys­tems simple, you can use channel tables instead of entering frequencies manually.

The R&S FPC1000 already comes with an assortment of channel tables that you can
use without doing anything. If you want to test transmission standards that are not lis­ted, you can also create your own channel tables with the "Channel Table Editor" of
the R&S InstrumentView software package. To use one of those, you just have to copy
the channel table to the R&S FPC1000.

For more information, refer to the R&S InstrumentView user manual.

1. Press the "Freq" key to open the frequency menu.

2. Select the "Frequency Mode" menu item to open the frequency mode.

3. Select the "Channel Downlink" or "Channel Uplink" menu item.

The R&S FPC1000 opens a dialog to select a channel table.

4. Select one of the available channel tables.

After activating the channel table, the R&S FPC1000 is configured according to the
information contained in the channel table. Instead of a center frequency, the
R&S FPC1000 shows the currently active channel number including the name of
the channel. The center frequency of a channel is defined in the channel table and
is the frequency corresponding to the selected channel.

Selecting a channel instead of a center frequency

When you have selected frequency input in terms of channels, entering a center fre­quency, start or stop frequency is not possible anymore.

Instead you select a channel. The R&S FPC1000 then adjusts the center, start and
stop frequency according to the channel table.

1. Press the "Freq" key to open the frequency menu.

2. Select the "Center Frequency" menu item.

The R&S FPC1000 opens an input field to select a specific channel.

3. Enter the channel you would like to analyze.

The R&S FPC1000 changes the frequency according to the channel table and the
channel you have selected.
Channel numbers are assigned to frequencies as follows.

• The first channel is assigned a channel number and a frequency.

• All subsequent channels have ascending numbers.

• The frequency spacing between channels is fixed. It can also be negative. In that

case, the center frequency of the R&S FPC1000 decreases with ascending chan­nel numbers.

• In transmission systems containing gaps in the frequency range (as in the case of
television, for example), a channel table can comprise multiple ranges.

9.4 Amplitude Configuration

Access: "Ampt"

Access: "Setup" > "Config Overview" > "Amplitude" (selected settings)

In addition to measuring the frequency of a signal, the other main function of a spec­trum analyzer is to measure level characteristics of the signal.

9.4.1 Reference Level

The reference level is the signal level that the analyzer expects at the RF input. In fact,
it should be slightly higher than the expected level of the signal you are measuring. If
necessary, the analyzer also attenuates or amplifies the signal to yield the best possi­ble dynamic range.

When you define a low reference level (meaning that a weak signal is expected), the
analyzer amplifies the signal internally to display even weak signals clearly. On the
other hand, when you apply a strong signal (or an unknown signal), you have to make
sure to define a reference level high enough for that signal to prevent an overload sit­uation in the signal path. A high reference level also keeps the displayed signal within
the display range.

If you are measuring the spectrum of a composite signal, make sure that the reference
level is high enough to cover all signals and that all signals are within the display

range.

In the measurement diagram, the reference level is represented by the topmost grid
line.

Defining a reference level

1. Press the "Ampt" key to open the amplitude menu.

2. Select the "Reference Level" menu item.

3. Enter the reference level.

When you change the reference level while a trace is already displayed, the
R&S FPC1000 adjusts the position of the trace.

The current reference level is indicated in the status bar. A blue dot in front of the
"Ref:" label indicates a reference level offset is active.

Defining a reference offset

The reference level offset is an arithmetic level offset. It shifts the measured levels by a
certain amount and changes the scale of the y-axis accordingly.

Such an offset is useful, for example, if you insert an external attenuator or amplifier
between DUT and RF input. The R&S FPC1000 automatically takes the loss or gain
into account when the level is displayed - no manual calculations are necessary. A loss
introduced at the RF input must be entered as a positive number, a gain as a negative
number.

Note, however, that the internal reference level (used to adjust the hardware to the
expected signal) ignores the reference offset. Thus, it is important to keep in mind the
actual power level that the R&S FPC1000 must handle. Do not rely on the displayed
reference level (internal reference level = displayed reference level - offset).

1. Press the "Ampt" key to open the amplitude menu.

2. Select the "Range / Ref Position" menu item to open the display range menu.

3. Select the "Reference Offset" menu item.

9.4.2 Measurement Sensitivity

The R&S FPC1000 provides several ways to improve (control) the sensitivity of a mea­surement.

RF attenuator

The internal RF attenuator is a hardware component to control measurement sensitiv­ity.

It is coupled directly to the reference level and has the following effects.

●

High attenuation protects the input mixer. Protecting the input mixer is the main
purpose of the attenuator.

●

High attenuation makes sure that the measurement results are reliable. Signals
that are stronger than allowed might distort the results.

●

High attenuation increases inherent noise (i.e. the noise floor) and thus decreases
measurement sensitivity: if you increase attenuation by 10 dB, the sensitivity is
reduced by 10 dB (in other words: the displayed noise increases by 10 dB).

●

High attenuation helps to avoid intermodulation.

Depending on the required test setup, a compromise must be found between a high
sensitivity, low intermodulation and input mixer protection. This is best done by letting
the R&S FPC1000 determine the ideal attenuation automatically. Determining the
attenuation automatically might not necessarily utilize the maximum dynamic range,
but still yields valid and reliable results.

When you select the attenuation manually and are measuring unknown signals, espe­cially DUTs with a high RFI voltage, always select the highest possible attenuation
level before you apply the signal.

If you need a better sensitivity or signal-to-noise ratio, make sure that the applied sig­nal does not exceed the specified limits, before you lower the attenuation.

2. Select the "Attenuator" menu item to open the attenuator menu.

3. The R&S FPC1000 provides several attenuation modes.

● "Manual Att <x> dB"

Defines the attenuation manually in 5 dB steps. The range is from 0 dB to
40 dB.
Manual attenuation is indicated by a blue dot in front of the "Att:" display in the
status bar.

Figure 9-8: Indicator of manual attenuation

● "Auto Low Distortion"

Selects an attenuation and gain that results in a good signal-to-noise ratio.
Thus, it reduces the display of spurious products. It also leads to an increased
display of the inherent noise (because of a higher attenuation).
See Table 9-1 for the dependencies between reference level and applied
attenuation.

● "Auto Low Noise"

Selects an attenuation and gain that increases the sensitivity of the
R&S FPC1000.
This mode gives a better impression of spurious products and is thus useful to
analyze signals whose level is near the noise level. However, the signal-to­noise ratio in general can deteriorate.
See Table 9-1 for the dependencies between reference level and applied
attenuation.

The current attenuation is indicated in the measurement settings.

Preamplifier

The internal 20 dB preamplifier is another hardware component to control measure­ment sensitivity.

When you turn on the preamplifier, all signals are amplified by 20 dB.

It has the following effects on measurements.

●

The preamplifier allows you to detect even weak signals.

●

The preamplifier reduces the noise figure of the R&S FPC1000 and thus increases
its sensitivity. Thus, it is recommended to use the preamplifier for measurements
that require a high sensitivity.

●

The preamplifier reduces the dynamic range. If you want to measure with the maxi­mum dynamic range, you should turn off the preamplifier.

The gain of the preamplifier is automatically considered in the level display.

Turning the preamplifier on and off

1. Press the "Ampt" key to open the amplitude menu.

2. Select the "Preamplifier" menu item.

The R&S FPC1000 turns the preamplifier on and off.

The status of the preamplifier is indicated in the status bar.

9.4.3 Scale of the Y-Axis

The scale of the y-axis depends on the unit you have selected for the measurement
and the display range.

Selecting the display unit

A spectrum analyzer usually shows signal levels in the unit dBm.

If necessary, you can also select other units. In that case, the analyzer automatically
converts the results into the selected unit.

1. Press the "Ampt" key to open the amplitude menu.

2. Select the "Unit" menu item to open the unit menu.

3. Select the one of the available display units.

The R&S FPC1000 adjusts the labels of the vertical axis accordingly.

Defining a display range

The display range determines the scale or resolution of the y-axis.

In the default state, the display range is a logarithmic scale over a 100 dB. This scale
corresponds to a resolution of 10 dB per grid division. The R&S FPC1000 provides
other display ranges that either increase or decrease the resolution of the y-axis.

Note that increasing the resolution of the y-axis does not increase the accuracy of
measurement results. It merely makes it easier to read the values of the trace.

You can also select a linear scale for the vertical axis. In that case, the power levels
are expressed as a percentage of the reference level. A linear scale is useful, for
example, to display AM modulated carriers in the time domain.

1. Press the "Ampt" key to open the amplitude menu.

2. Select the "Range / Ref Position" menu item to open the display range menu.

3. Select the display range you need.

● "Auto Range"

Automatically scales the y-axis for an ideal display of the measured signal.

● "Range <x> dB"

Opens an input field to define a custom display range.

● "Linear 0 - 100 %"

Changes the scale into a linear scale.
Note that "Auto Range" is not supported for a linear y-axis scale.

The R&S FPC1000 adjusts the vertical axis accordingly.

9.4.4 Transducers

The results of measurements with transducers or antennas usually need to be correc­ted by their frequency characteristics. These correction values are defined in trans­ducer factors. When you use a transducer factor, these correction values can be
directly considered in the measurement results.

A transducer factor consists of several data points, with each data point being defined
by a frequency and the corresponding correction value for that frequency. The unit of
the correction value depends on the transducer you are using. Field-strength measure­ments with an antenna, for example, indicate the electrical field strength in dBµV, so
the transducer factor has to define its level values in dBµ, too.

You can also use a transducer factor to correct a frequency-dependent attenuation,
e.g. of a cable between DUT and RF input of the R&S FPC1000.

You can create and edit transducer factor with the R&S InstrumentView software pack­age and then transfer them into the internal memory of the R&S FPC1000. Each trans­ducer factor can consist of up to 1000 reference values.

Interpolation between the values is performed with the aid of a modified spline algo­rithm. Even if only relatively few values such as maxima, minima and turning points are
available, this algorithm can easily simulate the correction factors of common transduc­ers. Two transducers can be switched on at a time. The second transducer must be

R&S®FPC1000

assigned the unit dB. The R&S FPC1000 adds the two transducers to a total trans­ducer.

Units supported for transducer factors:

●

dB

●

dBμV/m

●

dBμA/m

●

W/m2

The unit dB does not change the unit set on the R&S FPC1000. It can be used, for
example, to compensate for frequency-dependent loss and gain at the input of the
R&S FPC1000. The units dBμV/m and dBμA/m convert the output power of an
antenna into electric or magnetic field strength. The unit W/m2 is used to calculate and
display the power flux density.

For example, to compensate for the cable loss between the transducer and the RF
input, the R&S FPC1000 can use two transducers at the same time. One of them must
have the unit dB, however, i.e. it must correspond to one loss or gain value.

Selecting transducer factors

1. Press the "Ampt" key to open the amplitude menu.

2. Select the "Transducer" menu item to open the transducer menu.

Note: You can select two transducer factors, a primary transducer and a secon­dary transducer.

3. Select the "Select Primary" menu item.

The R&S FPC1000 opens a submenu where you can select the transducer factor
you need.

4. Select the transducer factor you need and confirm the selection with the "Load"
menu item.

The R&S FPC1000 applies the correction values to the measurement results.

An example would be the transducer factor of the R&S HL223 antenna that is defined
between 200 MHz and 1300 MHz. The R&S FPC1000 therefore displays the noise in
this frequency range as a function of frequency incremented by the transducer factor.
Outside the transducer range, the R&S FPC1000 sets the transducer factor at zero, i.e.
measurements in this range do not yield conclusive results.

You can select a second transducer factor with the "Select Secondary" menu item. The
secondary transducer factor in that case is added to the first. The unit of the second
transducer factor must always be the relative unit dB as otherwise an addition would
not be useful. When you select a secondary transducer factor, the dialog box shows
only those transducer factors that have dB as their unit.

Setting the unit for measurements with transducers

If the unit of the transducer is dB, the units dBm, dBmV or dBμV remain unchanged.
The linear units volt and watt are not allowed. They are deactivated in the units menu.

R&S®FPC1000

The Spectrum Application

Bandwidth Configuration

If the unit of the transducer is dBμV/m or dBμA/m, this unit is also used for the
R&S FPC1000 level display. This means that both the level axis of the diagram and the
level at the marker position are assigned the unit of the transducer. If dBμV/m is
selected as the transducer unit, a switch to absolute level indication in V/m is possible.

1. Press the "Ampt" key to open the amplitude menu.

2. Select the "Unit" menu item to open the unit menu.

3. Select the unit you need (note that you can select only units compatible to the
transducer factor).

The R&S FPC1000 applies the selected unit.

Tip: If you are using a transducer with the unit dBμA/m, it is not possible to select
another unit. Level indication is entirely in dBμA/m.

Defining the reference level

The transducer shifts the trace by its value as a function of frequency. Positive trans­ducer values increase the level, negative values reduce it. To ensure that the trace is
always within the diagram, the R&S FPC1000 adjusts the reference level accordingly.
The reference level is shifted by the maximum transducer value in the positive or nega­tive direction.

Frequency range of transducer

If the set frequency range is wider than the span in which a transducer is defined, the
R&S FPC1000 assumes the transducer values outside the defined range to be zero.

Data sets containing transducer factors

The R&S FPC1000 stores data sets together with any transducer factors that may
have been active for the measurement in question. When such a dataset is recalled,
the associated transducer factor(s) are switched on as well. Transducer factors recal­led as part of a data set do however not appear in the list of transducer factors.
