Portable Equipment for Observing Transient Response of Television Apparatus

An apparatus which supplies a perfect transient, either directly or as the modulation of an ultra-high-frequency carrier, to a television amplifier or receiver and records its transient response on the screen of a synchronized oscilloscope is described. Performance requirements are discussed and some design details described, among these a carbon-disk attenuator suitable for ultra-high frequencies, also a single-lever position control and a scale projection for the oscilloscope.
