Question

Introduction to the Oscilloscope

PLEASE WRITE THIS IN COMPUTER, NOT BY THE HAND

1. Mention the fundamental parts of an oscilloscope.
2. What is the purpose of the deflection plates in the oscilloscope?
4. Define peak voltage.
5. Define peak to peak voltage.
6. Determine effective voltage (Vrms).

Answer 1

1) The fundamental parts of an oscilloscope are

a) cathode ray tube

b) intensity and focus controls

c) position controls

2) purpose of deflecting plates in oscilloscope is to deflect the beam according to the voltage applied across them.

4) Peak voltage is the voltage waveform which is measured from the horizontal axis to crest.

5) Peak to peak voltage is the voltage waveform which is measured from the top of the waveform, crest to the bottom of the waveform, i.e trough

6) effective voltage of a waveform is the dc equivalent of an AC supply. it is 0.707 times the peak voltage
