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 unit oscillator of interest are used to create a oscilloscope display for the device under test. | |||
