The General Radio 1216-A Unit IF Amplifier and DNT Detector was introduced in 1954 Catalog N and remained available through Catalog T 1968.
Specifications
- Center Frequency: 30 MHz
- Bandwidth: 0.7 MHz at 3 dB down; 9.5 MHz at 60 dB down
- Attenuator Range: 0 to 70 dB in 10 dB steps, a single 3 dB step is also provided
- Sensitivity: Less than 2 μV input from a 400 Ω source required for a 1% meter deflection (above noise). Less than 50 μV input from a 400 Ω source required for full-scale meter deflection. Input voltages referred to are open circuit source voltages.
