The General Radio 1215-C Unit Oscillator was introduced in Catalog T (1968) and remained available through Catalog 1973.
The Type 1208-C is a general purpose frequency source covering 50 to 250 MHz. It finds use as a generator for bridges, admittance and impedance meters. Direct amplitude modulation at audio frequencies is provided by a front panel phone jack and with an accessory crystal-diode modulator 1000-P6, frequencies from 0 to 5 MHz can be used to provide amplitude modulation. As a unit oscillator it requires an external power supply, the types 1203-B is recommended.
