conductor test, insulation resistance
measurement, leakage current
measurement, functional test).

1171.0000.52-01.00 Sheet 2

Safety Instructions

3. As with all industrially manufactured
goods, the use of substances that
induce an allergic reaction
(allergens) such as aluminum
cannot be generally excluded. If you
develop an allergic reaction (such
as a skin rash, frequent sneezing,
red eyes or respiratory difficulties),
consult a physician immediately to
determine the cause.

4. Depending on the function, certain
products such as RF radio
equipment can produce an elevated
level of electromagnetic radiation.
Considering that unborn life requires
increased protection, pregnant
women should be protected by
appropriate measures. Persons with
pacemakers may also be
endangered by electromagnetic
radiation. The employer is required
to assess workplaces where there is
a special risk of exposure to
radiation and, if necessary, take
measures to avert the danger.

5. Operating the products requires
special training and intense
concentration. Disabled persons
should not use the products unless
it is made certain that their disability
has no adverse effects while they
are operating the products.

6. Prior to switching on the product, it
must be ensured that the nominal
voltage setting on the product
matches the nominal voltage of the
AC supply network. If a different
voltage is to be set, the power fuse
of the product may have to be
changed accordingly.

7. In the case of products of safety
class I with movable power cord and
connector, operation is permitted
only on sockets with earthing
contact and protective earth
connection.

8. Intentionally breaking the protective
earth connection 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.

9. If the product has no power switch
for disconnection from the AC
supply, the plug of the connecting
cable is regarded as the
disconnecting device. In such
cases, it must be ensured that the
power plug is easily reachable and
accessible at all times (length of
connecting cable approx. 2 m).
Functional or electronic switches
are not suitable for providing
disconnection from the AC supply. If
products without power switches are
integrated in racks or systems, a
disconnecting device must be
provided at the system level.

10. Never use the product if the power
cable is damaged. 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 e.g. tripping over the cable
or suffering an electric shock.

11. The product may be operated only
from TN/TT supply networks fused
with max. 16 A.

12. Do not insert the plug into sockets
that are dusty or dirty. Insert the
plug firmly and all the way into the
socket. Otherwise this can result in
sparks, fire and/or injuries.

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

1171.0000.52-01.00 Sheet 3

Safety Instructions

14. For measurements in circuits with
voltages V

> 30 V, suitable

rms

measures (e.g. appropriate
measuring equipment, fusing,
current limiting, electrical
separation, insulation) should be
taken to avoid any hazards.

15. Ensure that the connections with
information technology equipment
comply with IEC950/EN60950.

16. Never remove the cover or part of
the housing while you are operating
the product. This will expose circuits
and components and can lead to
injuries, fire or damage to the
product.

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

18. For permanently installed
equipment without built-in fuses,
circuit breakers or similar protective
devices, the supply circuit must be
fused in such a way that suitable
protection is provided for users and
products.

19. Do not insert any objects into the
openings in the housing that are not
designed for this purpose. Never
pour any liquids onto or into the
housing. This can cause short
circuits inside the product and/or
electric shocks, fire or injuries.

20. Use suitable overvoltage protection
to ensure that no overvoltage (such
as that caused by a thunderstorm)
can reach the product. Otherwise
the operating personnel will be
endangered by electric shocks.

21. Rohde & Schwarz products are not
protected against penetration of
water, unless otherwise specified
(see also safety instruction 1.). If
this is not taken into account, there
exists the danger of electric shock
or damage to the product, which
can also lead to personal injury.

22. Never use the product under
conditions in which condensation
has formed or can form in or on the
product, e.g. if the product was
moved from a cold to a warm
environment.

23. Do not close any slots or openings
on the product, since they are
necessary for ventilation and
prevent the product from
overheating. Do not place the
product on soft surfaces such as
sofas or rugs or inside a closed
housing, unless this is well
ventilated.

24. Do not place the product on heat­generating devices such as
radiators or fan heaters. The
temperature of the environment
must not exceed the maximum
temperature specified in the data
sheet.

25. Batteries and storage batteries must
not be exposed to high
temperatures or fire. Keep batteries
and storage batteries away from
children. If batteries or storage
batteries are improperly replaced,
this can cause an explosion
(warning: lithium cells). Replace the
battery or storage battery only with
the matching Rohde & Schwarz
type (see spare parts list). Batteries
and storage batteries are hazardous
waste. Dispose of them only in
specially marked containers.
Observe local regulations regarding
waste disposal. Do not short-circuit
batteries or storage batteries.

Connecting Peripheral Devices R&S FSP

Connecting USB Devices (e.g. a Pow er Meter)

The USB interface on the rear panel of the R&S FSP allows you to connect up to two USB
devices directly to the analyzer. This number can be increased as necessary by inserting
USB hubs.

Due to the large number of available USB devices, there is almost no limit to the
expansions that are possible with the R&S FSP. The following list shows various USB
devices that can be useful for the R&S FSP:

• Power Sensor R&S NRP-Z11 or R&S NRP-Z21
(requires Adapter Cable R&S NRP-Z4)

• Pendrive (memory stick) for easy transfer of data to/from a PC
(e.g. firmware updates)

• CD-ROM drives for easy installation of firmware applications

• PC keyboard for entering comments, file names, etc

• Mouse for easy operation of Windows dialog boxes

• Printer for printing out measurement results

• Modem for remote control of the R&S FSP over large distances

Installing USB devices is easy under Windows XP, because all USB devices are plug&play.
All USB devices can be connected to or disconnected from the R&S FSP during operation.

After a device is connected to the USB interface of the R&S FSP, Windows XP
automatically searches for a suitable device driver.

If Windows XP does not find a suitable driver, it will prompt you to specify a directory that
contains the driver software. If the driver software is on a CD, connect a USB CD-ROM
drive to the R&S FSP before proceeding.

When a USB device is subsequently disconnected from the R&S FSP, Windows XP
immediately detects the change in hardware configuration and deactivates the
corresponding driver.

1164.4556.62 2.8 E-1

R&S FSP Connecting Peripheral Devices

Example:

Connect a pendrive (memory stick) to the R&S FSP:

1. When you connect the pendrive at the USB interface, Windows XP detects the new
hardware:

2. Windows XP installs the corresponding driver.
If installation is successful, Windows XP informs you that the device is ready to use:

3. The pendrive is made available as a new drive and is displayed under Windows Explorer:

The pendrive can be used like a normal drive to load or store data.

4. If you no longer need the pendrive or if you want to transfer files to another computer,
simply disconnect the pendrive. Windows XP will automatically deactivate the driver.
If the drive is still selected in Explorer, an error message will appear indicating that the
drive is no longer available.

Connecting External Generators

The option External Generator Control R&S FSP-B10 allows you to operate a number of
commercially available generators as a tracking generator on the R&S FSP. When suitable
generators are used, the R&S FSP thus allows scalar network analysis to be performed also
outside the freqency range of the internal tracking generator. Appendix C provides a list of
generators supported by the option R&S FSP-B10.

DUT

The generator is controlled via the – optional – second IEC bus interface of the R&S FSP
(= IEC2, supplied together with the option). With some Rohde & Schwarz generators, it is
also controlled via the TTL synchronization interface that is contained in the AUX
CONTROL interface of the R&S FSP.

Notes: 1. Using the TTL interface allows you to attain significantly higher speeds

than possible with a pure IEC bus control, because the frequency
switching mechanism of the R&S FSP is directly coupled to the frequency
switching mechanism of the generator.

2. To increase measurement accuracy, use a shared reference frequency to
operate the R&S FSP and the generator. If no independent 10 MHz
reference frequency is available, connect the reference output of the
generator to the reference input of the R&S FSP and use SETUP –
REFERENCE EXT to configure the R&S FSP to implement the external
reference.

Installing Plug&Play Printers

Plug&play printers can easily be installed under Windows XP:
After you connect and switch on a printer, Windows XP automatically detects the printer and
installs the associated driver, provided that the driver is contained in the Windows XP
installation.

If Windows XP does not find the printer driver, it will prompt you to enter a path for the
associated installation files. In addition to the preinstalled drivers, a number of additional
printer drivers are found in the D:\I386 directory.

Note: When you install printer drivers that are not preinstalled on the instrument, the

installation process will prompt you to sp ecify the path containing the new driver.
This can be a disk in drive A. Alternatively, the driver can also be loaded from a
memory stick or USB C D-R OM driv e (see the section "C onnecting USB Devi ces").

Installing Non-Plug&Play Printers

The procedure for installing non-plug&play printers is described in the appendix.

Configuring the LAN Interface R&S FSP

Configuring the LAN Interface
(only with Option R&S FSP-B16)

The instrument can be connected to an Ethernet LAN (local area network) using the LAN
interface connector on the rear panel. This makes it possible to transfer data over the
network and to use network printers. In addition, the instrument can be remote-controlled
via the network. The network card can be operated with a 10 MHz Ethernet IEEE 802.3 or a
100 MHz Ethernet IEEE 802.3u interface.

Connecting the Instrument to the Network

Caution:

Before connecting the instrument to the network, consult your network
administrator, particularly in the case of large LAN installations. Connection
errors may affect the entire network.

Connect a conventional RJ-45 cable (not supplied) to the rear panel of the instrument and a
network hub of the required LAN segment. Since the RJ-45 involves star configuration
rather than bus cabling, no special measures need to be taken.

Setting up the connection does not cause any problems on the network. Likewise,
disconnecting the instrument from the network does not cause any problems as long as no
data traffic to and from the instrument is in progress.

Configuring the Network Card

Installation von Treibern

Under Windows XP, network card drivers do not need to be installed separately if the option
FSP-B16 has been factory-installed. All you need to do is connect the network cable to the
"LAN-Interface" connector on the instrument rear panel. Windows XP automatically detects
the network connection and activates the required drivers.

5 Introduction

This section provides a brief introduction on operating the Spectrum Analyzer R&S FSP. A
more detailed discussion of the basic operating steps, e.g. selecting menus and setting
parameters, plus measurement examples are provided in chapters 2, 3 and 4 of the
operating manual.

1164.4556.62 5.1 E-1

Measuring a Sinusoidal Signal R&S FSP

Measuring a Sinusoidal Signal

One of the most common measurement tasks that can be handled by using a spectrum
analyzer is determining the level and frequency of a signal. When measuring an unknown
signal, you can usually start with the PRESET setting.

Note: If levels higher than +30 dBm (=1 W) are expected or are possible, a power

attenuator must be inserted before the RF input of the analyzer. If this is not
done, signal levels exceeding 30 dBm can damage the RF attenuator or the
input mixer. The total power of all signals that are present must be taken into
account.

In the following examples, a signal generator is used as a signal source.

Test setup:

Connect the RF output of the signal generator to the RF input of R&S FSP.

Settings on the signal generator:

Frequency: 128 MHz
Level: -30 dBm

Measuring the Level and Frequency with Markers

The level and frequency of a sinusoidal signal can be measured easily by using the marker
function. The R&S FSP always displays its amplitude and frequency at the marker position.
The frequency measurement uncertainty is determined by the reference frequency of the
R&S FSP, the resolution of the marker frequency display and the resolution of the screen.

Procedure

1. Reset the instrument.

Ø Press the PRESET key

2. Connect the signal to be measured to the RF INPUT analyzer input on the
instrument front panel.

3. Set the center frequency to 128 MHz.

Ø Press the FREQ key.

The entry field for the center frequency appears on screen.

Ø Using the numeric keypad in the input field, enter 128 and confirm the entry with the

MHz key.

1164.4556.62 5.2 E-1

R&S FSP Measuring a Sinusoidal Signal

4. Reduce the frequency span (SPAN) to 1 MHz.

Ø Press the SPAN key.
Ø Using the numeric keypad in the input field, enter 1 and confirm the entry with the MHz

key.

Note: When the frequency span is defined, the resolution bandwidth (RES BW), the

video bandwidth (VIDEO BW) and the sweep time (SWEEP TIME) are
automatically reset, because these functions are l inked in the PRESET setti ng.

5. Measure the level and frequency using the marker and read the results from the
screen.

Ø Press the MKR key.

The marker is activated and automatically jumps to the maximum of the trace.

Note: When a marker is initially acti vated, it autom atical ly perfor m s the PEAK SEARCH

function (as shown in the example).
If a marker was already active, you have to press the PEAK key in the M KR->
menu in order to set the currently acti ve mar ker to the m axim um of the displ ayed
signal.

The level and frequency values measured by the marker are displayed in the marker
field at the top edge of the screen. They can be taken as the measurement result.

The field header indicates the number of the marker (MARKER 1) and the trace on
which the marker is located ([T1] = Trace 1).

Increasing the Frequency Resolution

The frequency resolution of the marker is predefined by the the pixel resolution of the trace.
A trace uses 501 pixels, i.e. when the frequency span is 1 MHz, each pixel corresponds to a
span of approx. 2 kHz. This corresponds to a maximum uncertainty of 1 kHz.
You can increase the pixel resolution of the trace by reducing the frequency span.

1. Reduce the frequency span (SPAN) to 10 kHz.

Ø Press the SPAN key.
Ø Using the numeric keypad, enter 10 in the entry field and confirm the entry with the

kHz key.
The generator signal is measured using a span of 10 kHz. The pixel resolution of the

trace is now approx. 20 Hz (10 kHz span / 501 pixels) , i.e. the precision of the marker
frequency display increases to approx. ±10 Hz.

1164.4556.62 5.3 E-1

Measuring a Sinusoidal Signal R&S FSP

Setting the Reference Level

With spectrum analyzers, the reference level (REF LEVEL) is the level at the upper limit of
the diagram. To achieve the widest dynamic range possible for a spectrum measurement,
use the entire level span of the spectrum analyzer. In other words, the highest level that
occurs in the spectrum must be located at the top edge of the diagram (=reference level) or
immediately below it.

Note: If the reference level that is selected is less than the highest signal that occurs

in the spectrum, the signal path in the R&S FSP will be overloaded.
In this case, the message IFOVL will appear on the left-hand edge of the diagram.

In the preset setting, the value of the reference level is -20 dBm. If the input signal is -30 dBm,
the reference level can be reduced by 20 dB w ithout causing the sig nal path to be ov erloaded.

1. Reduce the reference level by 10 dB.

Ø Press the AMPT key.

The AMPT menu will appear in the softkey bar. The REF LEVEL softkey will be
highlighted in red to indicate that it is activated for data entry. The entry field for the
reference level is also opened and displays a value of -20 dBm.

Ø Using the numeric keypad, enter 30 and confirm the entry with the -dBm key.

The reference level is now set to -30 dBm. The maximum of the trace is near the
maximum of the measurement diagram. However, the increase in the displayed noise is
not substantial. Thus, the distance between the signal maximum and the noise display
(=dynamic range) has increased.

2. Setting the marker level equal to the reference level

The marker can also be used to shift the maximum value of the trace directly to the top
edge of the diagram. If the marker is located at the maximum level of the trace (as in this
example), the reference level can be moved to the marker level as follows:

Ø Press the MKRÞ key.
Ø Press the REF LVL = MKR LVL softkey.

The reference level will be set equal to the measured level where the marker is
located.

Thus, setting the reference level is reduced to two keystrokes.

1164.4556.62 5.4 E-1

R&S FSP Measuring a Sinusoidal Signal

Measuring the Signal Frequency using the Frequen cy Counter

The built-in frequency counter makes it possible to measure the frequency more precisely
than measuring it with the marker. The frequency sweep is stopped at the marker, and the
R&S FSP measures the frequency of the signal at the marker position.

In the following example, the frequency of the generator at 128 MHz is shown by using the
marker.

1. Set the spectrum analyzer to the default state.

Ø Press the PRESET key.

The R&S FSP is in the default state.

2. Set the center frequency and the span.

Ø Press the FREQ key and enter 128 MHz.

The center frequency of the R&S FSP is set to 128 MHz.

Ø Press the SPAN softkey and enter 1 MHz.

The frequency span of the R&S FSPs set to 1 MHz.

3. Activate the marker

Ø Press the MKR key.

The marker is activated and set to the signal maximum. The level and the frequency of
the marker are displayed in the marker information field.

4. Activate the frequency counter.

Ø Press the SIGNAL COUNT softkey in the marker menu.

The result of frequency counting is displayed in the selected resolution (1 kHz in the

Measuring a Sinusoidal Signal R&S FSP

Fig. 5-1 Measurement of the frequency with the frequency counter

Note: Obtaining a correct result when measur ing the frequency wi th the internal

frequency counter requires that an RF sinusoidal si gnal or a spectral line be
present. The marker must be l ocated mor e than 25 dB above the noise l evel
to ensure that the specified measurement accur acy is adhered to.

Tip: For bandwidths between 300 kHz and 10 MHz, the time for measuring the

frequency is inversely proportional to the selected resolution, i.e. a
resolution of 1 Hz requires a gate time of 1 second for the counter.
For digital bandwidths of less than 300 kHz, the time for measuring the
frequency is always approx. 30 ms and is not affected by the resolution
that is set.
Thus, when measuring the frequency of a sinusoidal carrier that has high
resolution, set the resolution bandwidth to 100 kHz or less.

R&S FSP Measuring Harmonics of Sinusoidal Signals

Measuring Harmonics of Sinusoidal Signals

Measuring the harmonics of a signal is a very common task that can be optimally perf ormed
by using a spectrum analyzer.

In the following example, the generator signal with 128 MHz and -30 dBm is used again.

Measuring the Suppression of the First and Second Harmonic of an Input Signal

1. Spektrumanalysator in den Grundzustand setzen.

Ø Press the PRESET key.

The R&S FSP is now in the default state.

2. Set the start frequency to 100 MHz and the stop frequency to 400 MHz.

Ø Press the FREQ key.
Ø Press the START softkey drücken and enter 100 MHz eingeben.
Ø Press the STOP softkey and enter 400 MHz.

The R&S FSP displays the fundamental and the first and second harmonics of the
input signal.

3. For maximum sensitivity, set the RF attenuation to 0 dB.

Ø Press the AMPT key.
Ø Press the RF ATTEN MANUAL softkey and enter 0 dB.

4. To average (suppress) the noise, reduce the video bandwidth.

Ø Press the BW key.
Ø Press the COUPLING RATIO softkey.
Ø Using the cursor keys, select RBW/VBW NOISE [10].

The video bandwidth (VBW) will now always be set to less than the resolution bandwidth
(RBW) by a factor of 10.

5. Activate the marker.

Ø Press the MKR key.

Marker 1 will be activated and positioned to the signal maximum (fundamental at 128 MHz).
The level and frequency of the marker will be displayed in the marker information field.

6. Activate the delta marker and measure the harmonic suppression.

Ø Press the MARKER 2 softkey in the marker menu.

Marker 2 will be activated as the delta marker (Delta 2 [T1]). It automatically appears
on the largest harmonic of the signal. The frequency offset and level offset from
marker 1 are displayed in the marker field at the top edge of the screen.

Ø Press the MARKER 3 softkey in the marker menu.

Marker 3 is activated as the delta mar ker (Del ta 3 [T1]). It automatically appears on the nex t
largest harmonic of the signal. The frequency offset and level offset from marker 1 on the
fundamental are displayed in the marker field at the top edg e of the screen. (see Fig. 5- 3)

Fig. 5-3 Measuring the harmonic suppression of the internal reference generator.

Markers delta 2 [T1] and delta 3 [T1] show the offset of the first and second
harmonics from the fundamental.

Reducing Noise

The spectrum analyzer offers three means of effectively differentiating the harmonics of a
signal from the noise:

• Reducing the video bandwidth

• Averaging the trace

• Reducing the resolution bandwidth

Reducing the video bandwidth and averaging the traces cause the noise from the analyzer
or the DUT to be reduced, depending on which component is larger. Both averaging
methods reduce the measurement uncertainty particularly in the case of small signal-to­noise ratios, because the measurement signal is also separated from the noise.

R&S FSP Measuring Harmonics of Sinusoidal Signals

1. Reducing the noise by reducing the video bandwidth.

Ø Press the BW key.
Ø Press the VIDEO BW MANUA L softkey.
Ø Using the rotary knob (turning it counterclockwise), reduce the video bandwidth to 10

kHz (for example), or enter 10 kHz.
This clearly smooths the noise, and the sweep time will increase to 25 ms. In other
words, the measurement will clearly take more time. The video bandwidth that is
shown in the display is marked with an asterisk (*VBW) to indicate that it is no longer
coupled to the resolution bandwidth (see Fig. 5-4).

Fig. 5-4 Suppression of noise during harmonics measurement by reducing video

bandwidth

2. Recouple the video bandwidth to the resolution bandwidth.

Ø Press the BW key.

3. Reduce the noise by averaging the curve.

Ø Press the TRACE key.
Ø Press the AVERAGE softkey.

The noise component of the trace will be smoothed by averaging 10 successive
traces.

4. Switch off trace averaging.

Ø Press the CLEAR/WRITE softkey.

Measuring Harmonics of Sinusoidal Signals R&S FSP

5. Reduce the noise by reducing the measurement bandwidth.

The noise is reduced in proportion to the bandwi dth by r educi ng the r esoluti on bandwidth,
i.e. reducing the resolution bandw idth by a factor of 10 also reduces the noise by a factor
of 10 (which corresponds to 10 dB). The amplitude of sinusoidal sig nal s is not affected by
reducing the resolution bandwi dth.

6. Set the resolution bandwidth to 10 kHz.

Ø Press the BW key.
Ø Press the RES BW MANUAL softkey and enter 10 kHz.

The noise decreases by approx. 25 dB with respect to the previous setting. Since the
video bandwidth is coupled to the resolution bandwidth, it is reduced to 1 kHz in
proportion to the resolution bandwidth. This causes the sweep time to increase to 60
seconds.

7. Reset the resolution bandwidth (couple it to the span)

Ø Press the RES BW AUTO softkey.

R&S FSP Measuring Signal Spectra with Multiple Signals

Measuring Signal Spectra with Multiple Signals

Separating Signals by Selecting the Resolution Bandwidth

A basic feature of a spectrum analyzer is being able to separate the spectral components of
a mixture of signals. The resolution at which the individual components can be separated is
determined by the resolution bandwidth. Selecting a resolution bandwidth that is too large
may make it impossible to distinguish between spectral components, i.e they will appear as
a single component.

An RF sinusoidal signal will be shown on the spectrum analyzer screen by means of the
passband characteristic of the resolution filter (RBW) that has been set. Its specified
bandwidth is the 3 dB bandwidth of the filter.

Two signals with the same amplitiude can be resolved if the resolution bandwidth is smaller
than or equal to the frequency spacing of the signal. If the resolution bandwidth is equal to
the frequency spacing, the spectrum display screen will show a level drop of 3 dB precisely
in the center of the two signals. Decreasing the resolution bandwidth makes the level drop
larger, which thus makes the individual signals clearer.

The tradeoff for higher spectral resolution at a narrower bandwidth is longer sweep times at
the same span. Reducing the resolution bandwidth by a factor of 3 increases the sweep
time by a factor of 9.

Ø The two signals can be clearly distinguished by a 3 dB level drop in the center of the

screen.

Note: The video bandwidth is set to 1 kHz in order to m ake the l evel drop in the center

of the two signals clearly visible. At larger video bandwidths, the video vol tage
that results from envelope detection is not suffici ently suppressed. Thi s produces
additional voltages, which are visible i n the trace, in the tr ansition ar ea between
the two signals.

5. Set the resolution bandwidth to 1 kHz.

Ø Turn the rotary knob counterclockwise until the bandwidth indicates 1 kHz.

The two generator signals are shown with high resolution. However, the sweep time
becomes noticeably longer (600 ms), since it increases at a rate of 1/RBW2. At smaller
bandwidths (10 dB per a bandwidth factor of 10), the noise display decreases
simultaneously.

IF filtering is now performed using the FFT algorithm. The sweep time decreases
significantly from 600 ms to 15 ms (a factor of 40). The display update rate also
increases by almost the same ratio.

R&S FSP Measuring Signal Spectra with Multiple Signals

Measuring the Modulation Depth of an AM-Modulated Carrier in
the Frequency Domain

In the frequency range (scan) displ ay, the AM side bands can be resolved with a narrow bandwidth
and measured separately. The modulation depth of a carrier modulated with a sinusoidal signal
can then be measured. Since the dynamic range of a spectrum analyzer is very large, extremely
small modulation depths can also be measured precisely . For this purpose, the R&S FSP provides
measurement routines that directly output the modulati on depth numericall y in %.

the AM modulation depth from the level differences of the delta markers to the main mar ker
and outputs the numeric value in the marker information field.

Measurements in the Time Domain R&S FSP

Measurements in the Time Domain

In the case of radio transmission systems that use the TDMA method (e.g. GSM or IS136),
transmission quality is determined not only by spectral characteristics but also by
characteristics in the time domain. However, a timeslot is assigned to each user since
several users share the same frequency. Smooth operation is ensured only if all users
adhere exactly to their assigned timeslots.

Both the power during the send phase as well as the timing and duration of the TDMA burst
and rise and fall times of the burst are important.

Measuring the Power Characteristic

For measuring power in the time domain, the R&S FSP offers easy-to-use functions that
measure the power over a predefined time.
