Oscilloscope 101

In this lab we are going to analyze an oscilloscope.So the first thing we do is connect a function generator to the oscilloscope. Set the FG to produce a sinusoid with a frequency of 5.00 Khz. Then set it to have a peak-to-peak amplitude of 5 Volts. After moving the FG to the appropriate settings we are going to adjust the oscilloscope to correctly display the settings of the FG onto a graph. So our values were:

Period: 200 Microseconds
Peak-to-Peak Amplitude: 5 Volts
Zero-to-Peak Amplitude: 2.5 Volts
Anticipated Rms Value: 1.77 Vrms

Measurement by DMM
VDC= 0V
VAC= 1.66Volts

With the 2.5V offset on, the graph now shifts up 2.5Volts. When we switch the oscilloscope from ac to DC we now get the original graph.
We now set the graph to display the square wave. Our new unreliable DMM now measures.

VDC= 2.6V
VAC=7.6V

When we calculate the the square wave by hand we have a value of 3.43V. This value should be the same as the VDC measured by the DMM.

Now that we know how to measure the oscilloscope we are given two mystery signals.

For our first mystery signal
VDC of about .3 Volts
Frequency of about 0.1 khz
Pk-Pk amp of about .6 Volts

For our second mystery signal
VDC of about .8 Volts
Frequency of about 6.06 khz
Pk-Pk amp of about 1.6 Volts
