1263-A
The General Radio 1263-A Amplitude-Regulating Power Supply was introduced in Catalog O (1956) and remained available through Catalog P (1959).
The Type 1263-A is a power supply designed to maintain the output level of an the attached oscillator. Although compatible with most unit oscillators, any oscillator with similar power requirements can be used.
The 1263-A performs this by monitoring the RF output, then adjusting the oscillator's plate supply to maintain a constant amplitude. A two-pin Jones modulation connector is provided for unit oscillators requiring it for RF control. A Jones to phone jack adapter cable is required for those unit oscillators.
RF monitoring is accomplished with the Type 874-VR Voltmeter Rectifier connection. Front-panel blanking connections are provided for sweep operation using Type 1750-A.
The 1263-A paired with the 1750-A and a unit oscillator of interest are used to create an oscilloscope display for the device under test.
