Abstract :
A homodyne network analyzer (NWA) is presented that applies a novel SSB-modulator for modulating the test path. The unwanted or image sideband is suppressed more then 40 dB over the 8-12 GHz frequency range using a microcomputer to adjust the modulator to its optimal operating points. Measurements have been made with various test objects, confirming the applicability of the measurement procedure. Very fast measurement speed is possible.
