Rohde & Schwarz ZVC 20KHz – 8GHz Vector Network Analyzer

The Rohde & Schwarz ZVC is a 20 kHz to 8 GHz vector network analyzer engineered for precision RF component and system characterization in R&D and production environments. Built with an integral S-parameter test set featuring bidirectional active couplers and active SWR bridges, the four-channel analyzer delivers normalized measurement speeds under 125 µs/point and fully calibrated performance in under 240 µs/point. Dynamic range reaches 60–120 dB standard, extending beyond 130 dB at 10 Hz IF bandwidth, enabling detailed analysis of transmission and reflection characteristics across demanding frequency spans.
