Rohde & Schwarz Vector Voltmeter (software license)
The Rohde & Schwarz ZNL-K14 Vector Voltmeter (software license), part number 5603.3666.02, is an optional software feature for the R&S ZNL Vector Network Analyzer. This license enables the vector voltmeter functionality, allowing users to perform precise phase and amplitude measurements of two signals in the frequency range supported by the base instrument. The vector voltmeter mode is particularly useful for applications such as cable and antenna measurements, phase matching, and component characterization. The software provides a graphical user interface for easy operation and supports both magnitude and phase display. It is activated via a license key and does not require additional hardware.
