For testing phase detector, one output gives reference cosine function and other gives waveform that can be varied in phase from sine to cosine function, with choke of high or low output impedance. Q1 is modified Colpitts. Frequency stability is 1% from 1 kc to 100 kc with regulated power supply.－J.G. Peddie, Oscillator Generates Sine, Cosine Waves Simultaneously, Electronics,37:22, p 74.
