The General Radio 1215-C Unit Oscillator was introduced in Catalog R (1963) 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 meters, and impedance meters.

Direct amplitude modulation at audio frequencies is provided by a front panel phone jack. With a 1000-P6 Crystal Diode Modulator accessory, frequencies from 0 to 5 MHz can be used to provide amplitude modulation.

As a unit oscillator, the 1215-C requires an external power supply, type 1203-B is recommended.

Specifications

  • Frequency Range: 50 to 250 MHz
