Advantest R3767C Network Analyzer

The Advantest R3767C is a 2-channel vector network analyzer designed for RF and microwave component characterization from 40 MHz to 8 GHz. It delivers precise S-parameter, impedance, and time-domain measurements with 1 Hz frequency resolution and 0.002% accuracy. The instrument features a built-in S-parameter test set with dual SWR bridges, power splitter, and electronic switching for forward and reverse S-parameter acquisition.

A TFT color LCD supports simultaneous display of up to four diagrams and eight traces across four windows, enabling real-time multi-parameter monitoring during production and design validation.
