6.6 Vector Voltmeter (R&S FSH-K45)
With firmware option R&S FSH-K45 (order no. 1304.5658.02) you can use a R&S FSH
with tracking generator and VSWR bridge as a vector voltmeter.
A vector voltmeter performs reflection (S11) and transmission measurements (S21).
The tracking generator provides the signal source that generates an unmodulated
sinewave signal on a single frequency. Typical applications for a vector voltmeter are:
● adjustment of the electrical length of cables with a reflection measurement
● testing of the antenna elements of a phase-controlled antenna-array relative to a
reference antenna with a transmission measurement
► Press the MODE key.
► Press the "Network Analyzer" softkey.
► Press the MEAS key.
► Press the "Meas Mode" softkey.
► Select the "Vector Voltmeter" menu item.
The R&S FSH starts the vector voltmeter mode. It turns on the tracking generator
and the zero span mode.
