The R&S®NRVD performs power, level and voltage measurements from DC to 40 GHz. It operates like two independent R&S®NRVS power meters in one instrument performing simultaneous measurements and exchanging data with each other. The two channels can be set separately so that two completely different measurements can be carried out at the same time. The two measured values can also be related to each other for readout of reflection coefficient, SWR or return loss, for instance.
