Sweep generator produces time-varying constant-amplitude frequency signal for network under test, with out-put of network converted to logarithmic DC voltage for display of amplitude or gain on decibel scale of CRO or recorder. Sawtooth voltage for sweep, generated by first Optical Electronics 3329 IC, drives another 3329 that converts sawtooth into logarithmic signal for log-frequency output. Detector uses 9004 absolute-value module as linear detector, with 2357 logamp converting output to decibel scale. Resulting display is Bode plot of frequency response.- A Simple Sweep Generator, Optical Electronics, Tucson, AZ, Application Tip 10201.
