The General Radio 1214-M Unit Oscillator was introduced in 1959 Catalog P and remained available through Catalog S 1965.
The Type 1214-M is member of the Unit Oscillator family that uses a self contained power supply. The single 117N7 tube contains the power supply Rectifier and Beam PA as the oscillator. The 1 MHz output is used as generator for bridge measurements and is part of the 1610-AH capacitance measurement system. Other members of Type 1214 family are 1214-A, 1214-D, and 1214-E. Unlike others in 1214 family the 1214-M uses a transformerless power supply.
Specifications
- Frequency: 1 MHz.
- Frequency Accuracy: ±1%.
- Maximum Output: 300 mW into 50 Ω.
- Distortion: 3.5% with 50 Ω load.
