Rohde and Schwarz ZVH-K45 - Vector Voltmeter Measurement Option for ZVH

The R&S ZVH-K45 vector voltmeter option displays the magnitude and phase of a DUT on a fixed frequency. Therefore, the R&S ZVH can replace a conventional vector voltmeter for many applications. The required signal source and bridge are already available in the R&S ZVH.

Costs are saved and the test setup is significantly simplified, making the R&S ZVH-K45 ideal for field use. For relative measurements, the measurement results of a reference DUT are stored at the press of a button. Comparison measurements, e.g. between different RF cables and a reference cable (golden device), can be quickly and easily performed.

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
