The HP 435B RF Power Meter is an analog power meter, compatible with the entire series of 8480 power sensors. Depending on which sensor is used, the 435B can measure power from -65 dBm to +44 dBm, full scale, at frequencies from 100 kHz to 26.5 GHz. This versatile instrument also features < 1 % instrumentation uncertainty, low noise and drift, auto-zero, recorder output, optional battery operation, and long cable options up to 61 m (200 ft). Specifications. Frequency range: 100 kHz to 26.5 GHz (depending on power sensor used). Power Range (calibrated in watts and dB in 5 dB steps) with 8481A, 8482A, 8483A or 8485A: -25 dBm (3 uW) to +20 dBm, (100 mW) full scale. Power Range with 8481B or 8482B: +5 dBm (3 mW) to +44 dBm (25 W) full scale. Power Range with 8481H or 8482H: -5 dBm (0.3 mW) to +35 dBm (3 W) full scale. Power Range with 8484A: -65 dBm (300 pW) to -20 dBm (10 uW) full scale. Accuracy Instrumentation: ± 1 % of full scale on all ranges. Options. 001: Rechargeable battery installed provides up to 16 hours of continuous operation. 002: Input connector placed on rear panel in parallel with front. 003: Parallel sensor inputs front and rear panels, reference oscillator output on rear panel. 004: Delete power sensor cable.
