Abstract : The monitoring of two specific functions out of a series of twelve sampled functions was accomplished by using a 304H Dumont Scope on the output of the discriminator containing these functions. The sync monitoring pulse is derived from the battery sample, which is the voltage sample with the greatest negative amplitude in the commutated sequence. By use of the grid scale on the face of the oscilloscope and by adjustment of the 'Y' and 'X' amplifier gain controls, a visual scale is provided which gives a proportioned percentage change of the commutated sample under observation.
