The pre-owned R&S ZNB40 delivers metrology-grade S-parameter measurement from 9 kHz to 40 GHz, pairing a class-leading 140 dB dynamic range with trace noise below 0.004 dB to resolve deep filter notches and tiny mismatches.
Fast 4 ms, 401-point sweeps accelerate tuner and production throughput, while wide IF-bandwidth choices and a 98 dB power-sweep span accommodate both ultra-low-noise devices and high-power components. Available in two- or four-port form factors—with independent dual generators on the latter—the analyzer supports LAN/GPIB automation and advanced calibration kits.
Supplied fully tested, freshly calibrated and running current firmware, it offers immediate deployment and substantial CAPEX relief without compromising Rohde & Schwarz precision.
