Abstract
An RF carrier applied to the antenna input of a radio receiver under test is sequentially modulated with an audio signal to provide sequentially at the audio output of the receiver a signal plus noise signal and a noise signal, which audio output signals are compared to provide a ratio voltage which is displayed to permit adjustment of the level of the RF carrier to set said ratio at a predetermined value.
