1209-C
The General Radio 1209-C Unit Oscillator was introduced in 1963 Catalog R 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): .2%.
- Output Power: 150 mW into 50 Ω with Type 1269-A Supply.
