The Type 1216-A is an high gain amplifier operating at a fixed frequency of 30 MHz with a bandwidth of 0. | The Type 1216-A is an high gain amplifier operating at a fixed frequency of 30 MHz with a bandwidth of 0.7 MHz. | ||
Combined with a unit oscillator and mixer, it forms what General Radio called a DNT detector, which in its simplest form is a radio receiver whose frequency range is determined by the selected unit oscillator. | |||
The 1216-A is equipped with a meter for signal strength measurements using its built in attenuator. | |||
The meter can switched to monitor the input to the amplifier. | |||
An AVC function located on the attenuator switch is advantageous when using the 1216-A in the null detector role. | |||
The 1216-A contains its own power supply and connection for suppling power to an external unit oscillator. | |||
Front-panel binding posts provide an output of the demodulated signal. | |||
The recommended mixer for DNT applications is the [[874-MR]] with an upper frequency limit of 5 GHz. | |||
