Advantest R3767CG Network analyzer

The Advantest R3767CG is a vector network analyzer engineered for S-parameter characterization, impedance measurement, and multi-port device testing from 300 kHz to 8 GHz. The instrument delivers sweep times as short as 150 µs/point and supports forward/reverse S-parameter acquisition with a built-in test set. Its 50 Ohm output can be controlled across a +10 dBm to −10 dBm range with 0.01 dB resolution, enabling precision power management for diverse RF and microwave applications.
