Oscilloscopes

Introduction to Oscilloscopes

Purpose: To explore the properties and applications of O-Scopes
Introduction:
      the following is used

an Oscilloscope
a Function Generator set to 5kHz sine wave and 5 Volts
a DMM



     The oscilloscope was adjusted to show about 2 periods and above the x-axis. The period is 200 microseconds. The voltage was adjusted to have a peak-to-peak voltage of 5 volts. The was a measured DC voltage of 0V and an AC voltage of 1.05V.


    The DC offset  was set on the Function Generator measured a DC voltage of 2.517V and an AC voltage of 1.051V. It showed the following: 


    The  function generator was then used display square waves. The square waves gave a DC voltage of 2.516V and and AC voltage of 1.375V. The Oscilloscope displayed the following:

    Lastly, A mystery signal was given in for us to "find".Once the oscilloscope was properly adjusted.we saw the following:
                     

                                              

 From this we identified the signal as a time varying ramp function!


Oscilloscopes can show voltage in a circuit as well as how it varies with time. It can also calculate frequency and allows one to focus on certain parts of a signal.
