Switch on one of Agilent Technologies’ GSM test
sets and you’ll find your mobile finds service
immediately. Now make a call and you’re up and
running; ready to perform all the key transmitter
and receiver measurements. Built-in to every test
set you’ll find . . .
Transmitter tester
Transmitter measurements such
as power versus time, modulation
phase and frequency error, and
burst timing are made using a
fast DSP analyzer. There’s also
an accurate peak power meter
to perform the GSM average Tx
power measurement, taking samples only during the active part of
the burst.
Receiver tester
Receiver testing is done using an
accurate 0.3 GMSK source. The
wide dynamic range allows for
low-level sensitivity measurements
and high power tests to check for
receiver saturation. Mobile receiver
sensitivity is measured by making
bit-error-rate measurements on
Class Ia, Ib and II bits in either
raw or residual form.
Spectrum analyzer
The optional spectrum analyzer
completes the array of GSM measurements which can be made. It
provides high dynamic range pulse
on/off ratio measurements and
output RF spectrum tests. The
spectrum analyzer also makes an
excellent diagnostic tool for tracing
signals and finding problems.
Toolkit
The full-featured tool-kit includes
a power meter, CW RF synthesizer, audio synthesizer, frequency
vounter, DVM, audio analyzer,
oscilloscope and DSP Analyzer.
These tools can be configured
to measure just about any signal
a GSM phone can produce,
whether on a call or in test-mode.
Base station emulator
The GSM base station emulator
creates a test network to which the
mobile can camp and make calls.
The emulator is capable of causing
a ‘simple camp’ so that receiver
and transmitter functions can be
verified separately. A speech coder
is present to allow functional voice
testing. A variety of basic call processing features test the mobile as
if it were in a real network. These
features include hopped traffic
channels, call origination and
termination (both mobile and base
station), hand-overs, channel
assignments, Tx power control
commands and a choice of control
channel configurations.
Automatic software
The optional automatic test software is easy to use, fast and
simple to configure. With the
flexibility to allow test sequences
to be created and saved in minutes, automatic test software
personalizes the test set for each
part of the incoming inspection
or repair process.

Troubleshoot in test mode
What if the mobile is unable to find service and
make a call and you can’t find the source of the
problem? With a single key press, the test set can
be put into a special test mode, allowing un-synchronized mobile operation. The transmit and
receive portion of the mobile can then be measured separately.
Simplify mobile test
SIM (Subscriber Identity Module) cards are available to simplify mobile test by matching the information on the card (IMSI, MCC, MNC) with that on
the test set. They also enable the mobile to be put
into a special loop-back mode to perform the
receiver bit-error-rate test.
Compatibility
If you already own an 8922F/H test set, these can
be upgraded to 8922S/M. Contact your Agilent
Technologies representative for details. You can
take advantage of the higher performance without
re-writing your production test code. Code written
for the 8922G or 8922H test set is compatible with
the 8922M.
To facilitate traceable testing, the 8922S/M test sets generally follow the procedures as outlined in the associated
GSM recommendations, but do not necessarily meet the
exact requirements or cover all ranges, limits or conditions
required for type testing.

1 The 8922S/M have limited capability for this measurement (< 1 GHz, and limited
resolution bandwidth and spans).
2 The 8922S/M test set use a 3 pole resolution bandwidth filter to make these
measurements.
3 8922M test set only; an additional RF source, such as the 8657 Option 022 0.3
GMSK signal generator, is required to make this measurement.
4 An additional CW RF source (frequency range of 100 kHz to 12.75 GHz, no modu-
lation needed) is required to make this measurement.
