Abstract
The horizontal output stage of a television receiver is tested by denergizing the receiver so as to remove B+ voltage from the horizontal output stage, and then powering the horizontal output stage from an independent low voltage DC power supply through a switch which is turned on and off at the horizontal sweep frequency to permit making measurements of operating parameters of said horizontal output stage.
