Automatic amplitude stabilization of r-f test signals, within 1 db over 1,300 to 1 frequency range, is achieved by demodulating r-f output with D1 and feeding demodulated voltage back to grid Y of differential amplifier V4. Permits rapid and accurate response measurements over wide range without resetting signal level to input of device under lest.-A.
