Oscilloscope Lab Summary
- Basic Waveform Measurement:
To begin with, my initial frequency is about 200hZ.
1)My amplitude is 5.0V * 3.2 div = 16V
2)Cursor 1= 8.20V; Cursor 2=-8.20V
Vpk-pk= 8.20V - (-8.20V) = 16.4V
3)According to my O-scope the amp is 16.4V pk-pk.
- Erron C. Gleicher 18:08, 27 August 2007 (EDT):This is an example of a note I added later
The o-scope chops off the top or bottom of waveform if DC offset is too high.
A rising edge trigger means that the o-scope waits for a certain voltage on the rising edge of a waveform before it triggers a sweep.
- AC Coupling
AC coupling is better for viewing ripple voltage because it subtracts the DC signal.
Fall Time of AC coupling: Square Wave - 57.08 mS
What RC constant does this imply?
The cursor is reporting a frequency of 202.138 hZ in FFT mode. The function generator is at roughly 200 hZ.
My O-scope agrees well with the Fourier Series applet. The sine wave has one Delta while the sawtooth has succesive deltas that decrease to zero quickly and the square wave has succesive deltas that do not decrease to zero.
