ZNH option
R&S ZNH-K45 (order number 1334.6852.02) option is required to operate the
R&S
ZNH in the vector voltmeter mode.
Equipped with R&S ZNH-K45, you can use a R&S
ZNH 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 sin-
ewave 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
