General Radio 1211-C

unit oscillator General Radio 1211-C HF Unit Oscillator Available from 1963 to 1978+ Manuals General Radio 1211-C HF Unit Oscillator Manual 1211-0100-F 1962 (All manuals in PDF format unless noted otherwise)

The General Radio 1211-C HF Unit Oscillator introduced in 1963 Catalog R and remained available through Catalog 1978.

Frequency Range: 0.5 to 50 MHz in two ranges.
Frequency Calibration Accuracy: ±2 percent at no load.
Warmup Frequency Drift: 0.4% ±0.2%, largest at the high-frequency end of each range.
Output Power: At least 200 milliwatts into 50 Ω load at any frequency. Over the 0.5 to 5 MHz range, average output is approximately 1 watt; over the 5 to 50 MHz range, 0.4 watt.
