The Keysight / Agilent 8508A vector voltmeter is a fully-automatic tuned receiver that makes RF voltage and phase measurements easy.
The narrowband measuring technique gives a dynamic range of over 90 dB and a sensitivity of 10 µV to trace even the smallest signal.
The vector voltmeter also measures the difference between the two input channels with at least 0.1 degree resolution over a full +180 to –180 degree range, so it can be used for another complete set of measurements—such as electrical length, phase distortion, or impedance.
The standard unit is supplied with the HP 85081B input module, which has two high-impedance probe inputs that operate from 100 kHz to 1 GHz. Its ability to store reference and use it in later measurements means individual circuit sections can be characterized and adjusted independently.
Frequency Range:100 kHz to 1 GHz
Maximum Input:2V peak ac (+16 dBm1 ), ±50 Vdc
B-Channel Noise Level:10 µV (–87 dBm)
