The 8920B is a full-function RF test set with accuracy, speed, and flexibility for testing land mobile radios, cellular telephones, and other communications systems while improving throughput and quality in manufacturing.
The 8920B RF Communications Test Set is a full‑function instrument for testing land‑mobile radios, cellular phones and other communications systems. It offers high‑level GPIB commands, PCS and TDMA cellular adapters, and a variety of built‑in signal generators, analyzers and measurement modules to improve test throughput and quality.
The document provides detailed performance data, including RF frequency coverage, power output ranges, reference oscillator stability, switching speed and optional configurations such as high‑stability timebase, low‑level power measurement and additional audio filters. Options modify attenuation, power handling and measurement capabilities to suit specific test requirements.
| RF Frequency Range | 30 MHz to 1 GHz |
|---|---|
| Standard Output Level Range | –137 to –20.5 dBm into 50 W |
| Reverse Power (Standard) | 60 W continuous, 100 W for 10 s/min |
| Reference Oscillator Temperature Stability | +1 ppm (0 °C to +55 °C) |
| Switching Speed | <150 ms to be within 100 Hz of carrier |
The instrument covers a frequency range from 30 MHz up to 1 GHz.
The standard output level ranges from –137 dBm to –20.5 dBm into a 50 W load.
The TCXO reference oscillator has a temperature stability of +1 ppm over 0 °C to +55 °C.
Options such as 006 (6 dB), 007 (0 dB), 016 (16 dB) and 055 (mechanical variable) provide different fixed or variable attenuation and power handling levels.
