5.1 Manual Operation
The front panel of the R&S FPC 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 5-1: 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
19User Manual 1178.4130.02 ─ 07
R&S®FPC
Operation
Manual Operation
that menu item, the R&S FPC 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 5-2: 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 5-3: 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 5-4: 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 5-6: 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").
An empty space or special characters like _ ! @ # $ % ^ & * = ? are available by
pressing the "0" key several times.
●
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.
21User Manual 1178.4130.02 ─ 07
R&S®FPC
Operation
Screen Layout
If you confirm a value that has a unit with the "✓" key, the R&S FPC 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.

5.3 Remote Operation
There are various tools that allow you to operate the R&S FPC remotely from another
computer (for example PC or tablet).
To use the R&S FPC this way, you have to establish a connection between both devices via the LAN, Wi-Fi or USB interfaces of the R&S FPC.
Remote desktop (R&S InstrumentView)
R&S InstrumentView is a software that contains various useful tools, including a
remote desktop application. You can download the software, including a user manual,
from the Rohde & Schwarz website.
1. Install the software on a desktop PC or notebook.
2. Connect the R&S FPC to the computer with a LAN cable or a USB cable.
3. Start the software on the computer (use the desktop icon, or search for "InstrumentView" in the start menu).
4. Establish a connection to the R&S FPC in the "Connection Manager".
a) Select the "LAN" tab to configure the LAN properties.
b)
Select the pencil icon ( ).
c) Enter the IP address of the R&S FPC you want to connect to.

on the front panel.
Everything you do in the remote desktop application is also done on the connected
R&S FPC.
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 FPC 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 FPC.
2. Configure your tablet or phone as a hotspot for an ad-hoc connection (usually in
the phone settings).
3. Connect the R&S FPC 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.
The R&S FPC starts a search for all Wi-Fi networks it can find (mobile 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 FPC establishes the connection.
4. Start the R&S MobileView app on your mobile device.
The app shows a list of all R&S FPC devices that are connected to the hotspot.
5. Select the R&S FPC you want to connect to.
The app shows a live simulation of the R&S FPC, including all keys available on
the front panel.
Everything you do in the app is also done on the connected R&S FPC.

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 FPC 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 FPC 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.
