The General Radio 1211-C HF Unit Oscillator introduced in Catalog R (1963) and remained available through Catalog 1978.
The 1211-C is an updated version of 1211 unit oscillator series. Along with updated form factor for rack installations its distortion figure has improved. It features both variable capacitance and inductance for frequency control in two bands. The Type 1211-C like most "Unit" instruments requires an external power supply.
Specifications
- 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.
