Brief Introduction A cathode-ray oscilloscope is essentially an electrostatic instrument. It is an extremely versatile equipment, used to display variations of physical qualities in time. The CRO shows electrical oscillations as lines on a glass surface (screen). It works on the principle of displaying a luminescent “spot” on a zinc-sulphate coated screen that is caused by impinging electron beam. For an applied voltage, the beam is deflected proportionally. The CRO is also the only type of indicator that can provide continuous information for fast changing electrical parameters. It can also function as a voltmeter measuring peak voltage for a.c. source and e.m.f for
