Advantest R3767A Network Analyzer

The Advantest R3767A is a vector network analyzer that measures transmission and reflection characteristics across RF circuits, antennas, and electronic components from 300 kHz to 8 GHz. It delivers fast, accurate S-parameter and amplitude/phase measurements with 100 dB dynamic range and a noise floor of -100 dBm. The instrument supports single, 3-port, and 4-port configurations with measurement speeds as fast as 0.15 ms per point under normalized calibration.
