What is the function of delay time?
The delay Line retards the arrival of the input waveform at the vertical deflection plates until the trigger and time base circuits start the sweep of the beam. The delay line produces a delay of 0.25 microsecond so that the leading edge of the input waveform can be viewed even though it was used to trigger the sweep.
Define the terms accuracy, Precision, Resolution, Drift and Relative limiting error.
