Advantest R3765B Network Analyzer

The Advantest R3765B is a benchtop vector network analyzer engineered for precise S-parameter and impedance characterization of RF and microwave components across 40 MHz to 3.8 GHz. It delivers complex transmission and reflection measurements on two-port devices with 100 dB dynamic range and -100 dBm minimum displayed average noise level. The instrument combines a built-in signal source with integral receiver, 1 Hz frequency resolution, and 0.15 ms sweep speed per test point to enable rapid, accurate network parameter assessment.
