vides, including remote control operation.
General R&S FSW functions
The application-independent functions for general tasks on the R&S FSW are also
available for GSM measurements and are described in the R&S FSW user manual. In
particular, this comprises the following functionality:
●Data management
●General software preferences and information
The latest version is available for download at the product homepage
http://www.rohde-schwarz.com/product/FSW.html.
Installation
You can find detailed installation instructions in the R&S FSW Getting Started manual
or in the Release Notes.
2.1 Starting the GSM Application
GSM measurements are performed in a separate application on the R&S FSW.
Starting the GSM Application

Welcome to the GSM Application
R&S®FSW-K10
10User Manual 1173.9263.02 ─ 25
To activate the GSM application
1. Select the [MODE] key.
A dialog box opens that contains all operating modes and applications currently
available on your R&S FSW.
2. Select the "GSM" item.
The R&S FSW opens a new measurement channel for the GSM application.
The measurement is started immediately with the default settings. It can be configured
in the GSM "Overview" dialog box, which is displayed when you select the "Overview"
softkey from any menu (see Chapter 6.3.1, "Configuration Overview", on page 86).
Remote command:
INSTrument[:SELect] on page 189
Multiple Measurement Channels and Sequencer Function
When you activate an application, a new measurement channel is created which deter-
mines the measurement settings for that application. The same application can be acti-
vated with different measurement settings by creating several channels for the same
application.
The number of channels that can be configured at the same time depends on the avail-
able memory on the instrument.
Only one measurement channel can be active at any time. However, in order to per-
form the configured measurements consecutively, a Sequencer function is provided.
When the Sequencer is activated, the measurements configured in the currently active
channels are performed one after the other in the order of the tabs. The currently
active measurement is indicated by a symbol in the tab label. The result displays of
the individual channels are updated in the tabs as the measurements are performed.
Sequential operation itself is independent of the currently displayed tab.
See also the note on using the Sequencer function in MSRA operating mode in Chap-
ter 5.18, "GSM in MSRA Operating Mode", on page 80.
For details on the Sequencer function see the R&S FSW User Manual.
2.2 Understanding the Display Information

ferent information areas are labeled. They are explained in more detail in the following

About the Measurement
R&S®FSW-K10
14User Manual 1173.9263.02 ─ 25
3 About the Measurement
A basic GSM measurement in the R&S FSW GSM application includes a power vs
time and a spectrum measurement, as well as modulation accuracy (e.g. EVM, phase
error) for a GSM signal as defined by the relevant 3GPP standards. The I/Q data from
the GSM signal applied to the RF input of the R&S FSW is captured for a specified
measurement time. This data is demodulated and synchronized with a reference signal
to identify the individual frames and slots. The slots of interest are then analyzed in
order to display the spectral and power results either graphically or numerically, and to
calculate the modulation parameters.
The standard distinguishes between single-slot and multi-slot measurements. Single-
slot measurements analyze one slot - referred to as the "Slot to measure" - within the
GSM frame (which consists of 8 slots in total). Modulation-specific parameters such as
the phase error, EVM, or spectrum due to modulation are determined on a per-slot
basis. Multi-slot measurements, on the other hand, analyze a slot scope of up to 8 con-
secutive slots, each of which has different burst modulation characteristics. Power vs
time limit checks and the transient spectrum measurements, for example, are deter-
mined for multiple slots.
Statistical evaluation of several measurements is also possible. Finally, the GSM mea-
surement results can be exported to other applications.

15User Manual 1173.9263.02 ─ 25
4 Measurements and Result Displays
The R&S FSW GSM application provides two different measurements in order to deter-
mine the parameters described by the GSM specifications.
The default GSM I/Q measurement captures the I/Q data from the GSM signal. The
I/Q data includes magnitude and phase information, which allows the R&S FSW GSM
application to demodulate signals and determine various characteristic signal parame-
ters such as the modulation accuracy, power vs time, modulation and transient spec-
trum in just one measurement.
For multicarrier measurements, some parameters required by the GSM standard
require a frequency sweep with varying resolution bandwidths. Thus, a new separate
measurement is provided by the R&S FSW GSM application to determine the wide-
band noise in multicarrier measurement setups.
For details on selecting measurements see "Selecting the measurement type"
on page 83.

4.1 GSM I/Q Measurement Results
The I/Q data that was captured by the default GSM (Modulation Accuracy, etc.) mea-
surement can be evaluated using different methods. All evaluation methods available
for the GSM measurements are displayed in the selection bar in SmartGrid mode.

●
Select the "SmartGrid" icon from the toolbar.
●Select the "Display" button in the configuration "Overview".
●Select the "Display Config" softkey from the [MEAS CONFIG] menu.
●Press the [MEAS] key.
For details on working with the SmartGrid see the R&S FSW Getting Started manual.
By default, the GSM measurement results for I/Q measurements are displayed in the
following windows:
●Magnitude Capture
●PvT Full Burst
●Modulation Accuracy
●Power vs Slot
