Agilent-HP 435A Analog Power Meter

Specifications

The 435A Power Meter has a frequency range (dependent on power sensor) of 100 kHz to 18 GHz. The 435A meter is calibrated in watts and dBm. The accuracy is ±1% of full scale on all ranges. This accuracy is ensured by an internal automatic zeroing circuit which removes error due to the ambient temperature output of the power sensing device, and a calibration factor adjustment which compensates for error due to the frequency response of the power sensing device.
