HP 8508A Option 001
HP 8508A Vector Voltmeter
The HP8508A 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
5
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. Any CW source can be used as a
stimulus—even a source that is part of the device being tested—so measurements can be made under normal operating conditions. To adapt the
probe inputs for measurements in a 50 Ω environment, the HP 11570A
accessory kit provides two HP 11536A probe tees, an HP 11549A power
splitter, and two HP 908A 50 Ωterminations. Option 050 is supplied with
the HP 85082A input module. Its 50 Ω inputs operate from 300 kHz to
2 GHz, and provide the accuracy and dynamic range to make measurements on active and passive components.
