Advantest R3765BH 40MHz – 8.0GHz, Built-in SWR Bridge Network Analyzer

The Advantest R3765BH is a network analyzer engineered for precision impedance matching and high-frequency reflection measurements across 40 MHz to 8.0 GHz. A built-in SWR bridge enables efficient characterization of RF and microwave components, while simultaneous 8-trace capability on a full-color TFT display accelerates design validation and production testing. The instrument measures amplitude, phase, group delay, and impedance with 100 dB dynamic range and 0.5 dB output accuracy.

Sweep speeds reach 0.15 ms/point with normalized calibration or 0.25 ms/point under 2-port full calibration, supporting rapid data acquisition in laboratory and manufacturing environments.
