- The technique of adding a precise amount of time between the trigger point and the beginning of the scope sweep in a CRO is known as the delayed sweep.
- The input signal is not directly applied to the vertical plates because the part of the signal gets lost when the delay time is not used.
- Therefore, a delay line is placed between output of vertical amplifier and y input of cathode ray tube, to delay incoming unknown signal.
