The | The {{Title|General Radio 1215-C Unit Oscillator}} was introduced in {{Catalog R}} 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. | The Type 1208-C is a general purpose frequency source covering 50 to 250 MHz.
