The Keysight/Agilent/HP 8920B RF Communications Test Set consolidates the functionality of over 20 individual radio test instruments into a single portable unit. Engineered for service and manufacturing environments, it delivers integrated signal generation, RF analysis, and power measurement capabilities for land mobile radios, cellular phones, and diverse communication systems. The 8920B features a dedicated call processing interface, built-in IBASIC computer with PCMCIA memory card support, and front-panel firmware update capability.
Technical Specifications
Signal Generator: 30 MHz to 1 GHz fundamental frequency range (extendable to 250 kHz–1000 MHz with options), 1 Hz resolution. Output levels span −137 dBm to +3.5 dBm into 50 Ω with ±1.2 dB accuracy (≥−127 dBm) and ±1 dB at duplex port. Modulation support includes AM (20 Hz–25 kHz rate, ±5% reading ±1.5% accuracy at 50 Hz–10 kHz) and FM (20 Hz–25 kHz rate, ±3.5% deviation accuracy, <0.5% distortion, <7 Hz rms residual FM per CCITT).
RF Analyzer: 10 MHz to 1 GHz measurement range (400 kHz–1 GHz with optional spectrum analyzer). Receiver sensitivity at ANT IN typically <1 µV. Spectrum analyzer offers variable frequency span from 5 kHz to 1 GHz full span with selectable display resolution (1, 2, or 10 dB per division).
Power Measurement: Reverse power handling ranges from 1.2 W continuous (Option 007 low-power) to 100 W continuous (standard, Option 016, Option H08). Standard configuration supports 60 W continuous, 100 W for 10 seconds per minute. RF In/Out maximum input power rated at 5 W with input level range from −137 to −20.5 dBm into 50 Ω.
