Advantest R3765AG/R3765BG/R3765CG – Network analyzer

The Advantest R3765AG/R3765BG/R3765CG are high-performance network analyzers for precise RF component, circuit, and system characterization from 300 kHz to 3.8 GHz. These instruments deliver 100 dB dynamic range and ±0.5 dB output accuracy, enabling fast, reliable measurements in both R&D and production environments. Measurement speed reaches 0.15 ms per point with 2-port full calibration. The 8.4-inch color TFT display supports four-window splitting for simultaneous observation of up to eight parameters across multiple signal paths.
