INTRODUCTION TO CRO

Versatile electronic instrument giving visual display of

signals

Used for measurement of frequency , amplitude,

phase etc.

Also used in determining the nature and

characteristics of various components.

Has a high bandwidth range thus making it a sensitive

and accurate device.

Easier to use as the internal routine act as a guide

to the user.

WORKING OF A CRO

THE MAIN PARTS OF

CATHODE RAY TUBE

ARE:

  • Electron Gun Assembly
  • Focusing Anodes
  • Deflection Plates Assembly

Screen for CRT

The most common one is of - TWO INPUTS

.

Although FOUR and EIGHT inputs are

available for special applications

SOME EXAMPLES OF
LISSAJOUS FIGURES……..

 With the help of lissajous figures we

can measure…….

 Frequency

 Phase
