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]] | The Type 1263-A is a power supply designed to maintain the output level of an the attached oscillator.
