Abstract
A multiburst test signal generator and a method for using the generator's test signal to determine the frequency response characteristics of television video circuits with a high degree of accuracy is described. One of the burst frequencies is continuously enabled and made variable and the other burst frequencies are disabled. The resulting continuous sine wave is applied to the circuit being tested, its frequency is varied, and the output of the circuit being tested is monitored with a conventional frequency counter.
