Welcome to
Azur Electronics
The HP 8922A GSM RF Test Set contains a complete set of instrumentation for testing the RF sections of GSM radios. In addition to the frequency agile 0.3 GMSK RF generator, the RF analyzer has an agile local oscillator, coherent data demodulator, pulse demodulator, FM demodulator, global method analyzer for phase and frequency error, synthesised spectrum analyzer, and pulsed power meter.
The 8922A also contains general purpose tools useful for module test, troubleshooting and debugging activities. These tools include a digital oscilloscope, a CW RF frequency counter, a CW RF power meter, an ac & dc voltmeter, a 1kHz distortion/SINAD meter, an audio frequency counter and a synthesised audio source.
The 8922A cost $61,350 plus $1,775 for the Option 001 High Stability Timebase, in 1993.

This was bought on eBay as part of a job lot of equipment together with an original Operating Manual. In good condition, it just needed a superficial clean-up and a few stickers removed. After the usual checks it was powered-up and passed its self tests ok.
March 2016
Although the 8922A is a very useful multi-purpose item of test equipment, it doesn't have full service information available. So the 8922A is for sale together with the Operating Manual. SOLD.
