ABSTRACT:
A network analyzer is coupled to a multi-band sweep oscillator and a display device to provide measurement and plotting of circuit parameters. Bi-directional interface circuits allow phase locking by the network analyzer over broad frequency sweeps and enable smooth and accurate plotting of system parameters despite frequency band switching by the sweep oscillator and relocking on new harmonic numbers by the network analyzer.
