1209-C

The General Radio 1209-C Unit Oscillator was introduced in Catalog R (1963) and remained available through Catalog S (1965).

The Type 1208-C is a general purpose frequency source covering 250 to 960 MHz. Direct amplitude modulation at audio frequencies is provided by a front panel phone jack and with an accessory crystal-diode modulator (1000-P6 or 1000-P7), frequencies from 0 to 5 MHz can be used to provide amplitude modulation.

Specifications

• Frequency Range: 250 to 960 MHz
• Frequency Calibration Accuracy: 1%
• Warmup Frequency Drift (Typical): 0.2%
• Output Power: 150 mW into 50 Ω with Type 1269-A Supply
