An oscillator apparatus and method for use in determining the linearity of output of a single sideband radio transmitter in which first and second oscillators are provided for generating respective audio tone signals having first and second frequencies. Each oscillator has a tone amplitude control for adjusting the amplitude of the signal produced. The signals are added, combined, and delivered to a transmitter in such a manner as to permit adjustment of oscillator and transmitter performance to a selected fraction of rated output power on each signal alone. Such adjustment makes possible a determination of linearity as described in the specification.
