HP 8920B is a full-function test set based upon the HP 8920A design but with increased measurement speed, accuracy, and larger user memory (928 kbytes standard). The HP 8920B uses PCMCIA memory cards for data storage and radio test programs. The HP 8920B has the functionality, speed, and accuracy for testing land mobile radios, cellular telephones and other communications systems while improving throughput and quality in manufacturing.

The HP 8920B can be configured to test both analog cellular TDMA dual-mode cellular phones by adding the following options. Option 500 adds the HP 83201B Option 003 TDMA Cellular Adapter to the HP 8920B. Option 001 adds the high-stability reference oscillator for the best frequency accuracy. Option 004 adds the necessary tone and digital signaling for AMPS/TDMA signals, and Option 051 consists of rear panel connectors to combine the two units.

The HP 8920B combines a faster processor, increased user memory, and other new features to gain measurement speed over standard HP-IB instruments and the HP 8920A.

HP 8920B Has High Performance and Accuracy as Standard Features

Along with speed enhancements, the HP 8920B has signal generator level accuracy or ± 1 dB at the duplex port and power measurement accuracy or ± 5% for levels from 1 mW to 60 watts at the RF In/Out port. Residual FM is less than 7 Hz rms, CCITT. For audio tests, the variable frequency notch filter from 300 Hz to 100 kHz is standard. The FM deviation accuracy is 3.5% and FM distortion less than 0.5%. HP-IB, RS-232, and Centronics port are standard.

Spectrum Analyzer with Tracking Generator and Adjacent Channel Power

The optional synthesized spectrum analyzer measures signals from 400 kHz to 1 GHz with variable spans from 5 kHz to 1 GHz (full span). Resolution is selectable with 1, 2, or 10 dB per division. The tunable marker provides readout of frequency, amplitude, or relative frequency and amplitude from a reference. The tracking generator included with the spectrum analyzer allows for swept characterization of devices with sweep spans to 1 GHz. The adjacent channel power measurement capability includes both variable bandwidths and variable frequency offsets. Typical performance is -70 dBc.
