The Rohde & Schwarz ZNB40 is a high-performance vector network analyzer engineered for RF component and system characterization to 40 GHz. It delivers exceptional dynamic range up to 140 dB, trace noise below 0.004 dB RMS, and measurement speeds better than 5 µs per point. The instrument combines rapid sweep capability with outstanding temperature stability and extended calibration intervals, supporting both 2-port and 4-port configurations for standard and advanced measurement applications including differential and frequency-converting tests.
