ABSTRACT:
Apparatus utilizing single sideband techniques for generating a local oscator signal of high spectral purity which is offset from a relatively wide-band signal generator frequency f.sub.g = 0.8 - 220MHz by a constant IF frequency difference f.sub.o = 46KHz. The output signal is coupled from one of a plurality of phase locked oscillators having overlapping frequency ranges which act as active filters to obtain improved spectral purity.
