Oscilloscope LabSJK 00:37, 17 September 2008 (EDT)
For this lab, I became familiar with a digital oscilloscope. I plugged in the BNC cable from the oscilloscope to the function generator. Then, I created a sine graph on the screen. I then took some measurements:
Measuring DataSJK 00:33, 17 September 2008 (EDT)
My first sine graph
1.) Increased the volts:
2.) Decreased volts (lowest voltage on the F.G.):
Note: The function generator could be set at any voltage (voltage only determines amplitude). The frequency at which it's set is very essential. If the frequency is too low, you'll get a condensed off scale sine graph. If the frequency is too high, you will just see a line, or half a sine graph. So I adjusted the frequency according, not too high or too low.
1.) Measure Button - Gives data automatically.
2.) The Grid - Using the boxes on the grid, you can determine voltages and times.
3.) Cursor Button - Set cursors, determine measurements.
Triggering enables the user to move along back and forth in the times of the wave.
I applied a large DC voltage of 12V (as instructed),and I decreased the frequency on the function generator substantially down to about 1 X 2.0 Hz. Instead of a round graph, I changed it to square. I adjusted the screen. Then, I measured the fall and rise times by using the measure button, an equation on Wikipedia, and with the cursor button:
