Used with spectrum analyzer to generate CW signal corresponding to frequency to which analyzer is tuned, for evaluation of filter response.Q1 and Q2 provide gain and isolation between 200-MHz oscillator, Q3 and first IF amplifier of analyzer. R1 provides fine tuning. MX1 mixes 200-MHz output with signal from 200-300 MHz first local oscillator to provide 100-kHz to 100-MHz tracking signal. Optional 130-MHz low-pass filter attenuates 400-500 MHz component generated by mixer in tracking generator-W, Ryder, Spectrum Analyzer Tracking Generator, Ham Radio, April 1978, p 30-32.
