The 8922M is a powerful GSM RF Test Set designed for high volume manufacturing. Flexible, but easy to use, its extensive feature set makes it the ideal choice when speed, accuracy and repeatability are key to minimizing production costs. When used in conjunction with a Keysight 83220A/E, the frequency range of the 8922M is extended to cover the DCS1800 and PCS1900 bands. The 8922P, based on the 8922M and 83220E, enhances the 8922M by adding Dual-band assignment capability.
The first choice for GSM mobile service and repair. Troubleshoot and find faults fast with the 8922M GSM MS service test set. Use it to reduce false failures with a test set that combines versatility with ease-of-use. Serving the needs of the GSM mobile manufacturer Maximize production throughput and minimize the cost per test with the 8922M GSM MS test set. It offers the highest speed of test in its class while guaranteeing accurate and repeatable measurements. Expand to DCS1800 or PCS1900 Add the 83220A/E test set to test DCS1800 and PCS1900 mobiles.
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 a 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 892SM. 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.
Testing Features
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 counter, 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.
