Experiment: 01

Using oscilloscope and Function Generator

Objective:

To familiarize with the use Oscilloscope and Function generator for Measurement and Testing

purposes.

Equipments and Components:

Oscilloscope

Function Generator

Theory:

Oscilloscope is used for voltage measurement. Unlike a voltmeter, an oscilloscope does not display

a single number. An oscilloscope displays signals - voltages that are functions of time. Oscilloscopes

can measure signal parameters - like frequency, peak-to-peak voltages, RMS values of signals



3

A function generator generates defined signals for test roles. These are sinusoidal signals, triangles,

square wave signals and even random signals.

Measuring:

Connect the probe of oscilloscope to voltage measuring point.

Be sure that, the two grounds connected together and selected in the active channel

Press the auto scale button to see the graph, or use manual setting (Change the value of horizontal

and vertical setting)

Generator:

Set the frequency of signal generator output to 5 kHz.

Set the amplitude of signal generator output voltage to 3 V peak – to – peak.

Procedure:

Generate the Square wave for 2 kHz, 3 volt peak to peak and measure the frequency utilizing from

screen.

Generate the Sine wave for 0.05 kHz, 2.5 volt peak to peak and measure the frequency utilizing from

screen.

Generate the Triangular wave for 1500 Hz, 3 volt peak to peak and measure the frequency utilizing from

screen.
