The General Radio 736-A Wave Analyzer was introduced in Catalog K1 (1939) and remained available through Catalog Q (1961).

The Type 736-A Wave Analyzer is used to measure the amplitude and frequency of components of a complex electrical waveform with 4 Hz bandwith. It performs this by the heterodyne method.

The band of frequencies between 20 Hz and 16 kHz are heterodyned or mixed with the local oscillator producing an intermediate frequency of 50 kHZ along with its sidebands. The frequencies applied to the input of the instrument are rejected by the 50 kHz tuned IF. A ballanced mixer cancels the local oscillator and the three stage crystal filter rejects the lower sideband. The upper sideband is then amplified by the following three stages and applied to the panel meter. The frequency dial is calibrated in the frequency applied to the panel meter. Under a cover at the base of the instrument are the calibration controls.

The Type 736-A can be used to measure harmonic distortion in amplifiers and radio receivers. It also finds use as null detector at audio frequencies, the measurement of hum and as a sharply tuned voltmeter.
