Question

The delay time of CRO is​

Answer 1

Answer:

Delayed time base oscilloscope:

Due to triggering of time base by input signal, sweep starts well in time and when input appears at vertical sections, the sweep is triggered and delayed W(l\ dorm is displayed. The delay ensures that no part of the waveform gets lost.

Answer 2

Answer:

about 80 ns

EXPLANATION

The delay that is caused by the horizontal deflecting circuits is about 80 ns. In order to present the leading edge of the signal under observation, the signal to the vertical deflecting plates must be delayed by the same time atleast. The delay line provides the required delay to the vertical deflecting voltage.
