The HP 436A Power Meter is a general purpose digital power meter intended for manual and automatic RF and microwave power measurements. It is compatible with the entire series of HP 8480 Power Sensors. Depending on which power sensor is used, the HP 436A can measure power from -70 dBm (100 pW) to +44 dBm (25W) at frequencies up to 50 G Hz. The HP 436A measures either absolute or relative power. It displays absolute power in either watts or dBm, and relative power in dB. Specifications. Frequency range: 100 kHz to 50 GHz, sensor dependent. Power Range: (display calibrated in watts, dBm, and dB relative to reference power level). -70 to +44 dBm (100 pW to 25W), sensor dependent. Instrumentation Accuracy. Watt mode: ± 0.5%. dBm mode: ± 0.02 dB ±0.001 dB/C. Zero: automatic, operated by a front-panel switch. Zero set: ±0.5% of full scale on most sensitive range, typical. Zero carryover: ± 0.2% of full scale when zeroed on the most sensitive range. Power reference: internal 50 MHz oscillator with Type N female connector on front panel (or rear panel , Option 003 only). Power output: 1.0 m W. Factory set to ±0.7% traceable to the U.S. National Institute of Standards and Technology. Accuracy: ± 1.2% worst case (±0.9% rss) for one year. Option 003: Reference oscillator output on rear panel only. Option 004: Delete power sensor cable. Option 022: Digital input/ output, fully compatible with HP Interface Bus (HP-IB).
