The Rohde & Schwarz NRVD is a dual-channel RF power meter engineered for precise power measurements from DC to 40 GHz. Operating as two independent measuring instruments within a single unit, it delivers simultaneous measurements across different frequencies—a capability that significantly enhances measurement efficiency in R&D, manufacturing, and service environments. The instrument measures power across a dynamic range spanning 100 pW to the kW range and supports power, level, voltage, attenuation, and reflection measurements.

– Typical Applications
The NRVD addresses demanding measurement requirements in RF and microwave environments. When used with an SWR bridge and appropriate sensors, it directly indicates reflection coefficient, SWR, and return loss—making it suitable for antenna characterization, component testing, and transmission line analysis.
