The Anritsu ME7838D VectorStar Broadband Vector Network Analyzer delivers high-performance S-parameter measurement from 70 kHz to 145 GHz in a single sweep. This coaxial-port instrument characterizes passive and active components across near-DC through W and F bands, supporting on-wafer device testing and high-frequency subsystem validation. Dynamic range exceeds 120 dB at 10 MHz, declining to 94 dB at 145 GHz. Measurement speed reaches 110 ms for 401-point sweeps at 10 kHz IF bandwidth. The system maintains 0.1 dB gain and 0.05° phase stability over 24-hour periods, delivering the repeatability required for production-grade RF characterization.
