Oscilloscope

Statement of Purpose
To learn the utility of a oscilloscope in electronic circuits.

Procedure

Period: 200 micro seconds

  Peak-to-Peak Amplitude: 11.4V

  zero-to-peak amplitude: 5.8V

 

  expected RMS value: 5.336V

 

So we measure to confirm,

Here a DC offset of 2.5V was set in the function generator.

The following measurements with the DMM were made.
VDC = 2.51 V
VAC = 3.37 V

Next, a squarewave function was generated.

 

 The following measurements with the DMM were made.
 VDC = 10mV
 VAC = 5.33 V

With a mystery signal, adjusting the oscilloscope properly is important to seeing the correct signal.

Conclusion
Oscilloscope allows us to graphically view an electric signal. Without such a device we can only make quantitative measurements which does not always give us a full picture of an electronic circuit.
