Oscilloscope lab notes

 * Acquire the necessary equipment
 * Plug in the power to the oscilloscope and function generator
 * Next connect the function generator to the oscilloscope's channel 1
 * Turn both pieces of equipment on, the power button on the oscilloscope is found on top, while the power button on the function generator is on the front "power" is labeled in red for easy identification.
 * I set the sweep/function generator range to 100.
 * I "played" with the oscilloscope until a sin function could be seen. Next I took some measurements of the initial sin function, using the grids, the cursors, and the measurement button.  Note that the initial sin wave also had some amount of DC offset (the dial was turned up about halfway.
 * Next I enlarged my power output using the function generator, I used the output dial.
 * Next I took the measurements of a small sin wave. This time I adjusted the wave by shrinking the output level from the sweep/function generator.  (As shown to me by our TA: Pranav).
 * Finally I measured my initial sin wave using DC a high DC offset, unfortunately I forgot to record the measured DC offset(the nob was turned all the way to the right).

Ac coupling

 * Which mode is better for viewing a ripple in DC coupling? AC couple is better for this since Ac coupling doesn't allow DC current to pass through.  The advantage being you can screen for "noise" with AC coupling.
 * Fall Time of wave using measure: 97.5ms
 * Cursor1:103.0ms; cursor2: 204.0ms
 * Fall time of wave using using cursors: 204-103=101ms



measurements
peak-to-peak Amplitude of initial sin wave using grid: 5.80V Peak-to-peak amplitude of initial sin wave using cursors: (cursor1: -3.76V, cursor2: +2.04V), 2.04V-(-3.76V)=5.80V peak-to-peak amplitude of initial sin wave using measure: fluctuated between 5.76V-5.84V

peak-to-peak amplitude of large sin wave using grid:2.2 squares=13.0 peak-to-peak amplitude of large sin wave using cursors: (cursor1:-6.48V, cursor2:6.48V), 6.48V-(-6.48V)=12.96V peak-to-peak amplitude of large sin wave using measure: 13.0V

peak-to-peak amplitude of small sin wave using grid:2.6V peak-to-peak amplitude of small sin wave using cursors:(cursor1:-1.40V, cursor2:1.20V) 1.20-(-1.40)=2.60V peak-to-peak amplitude of small sin wave using measure: 2.60V

peak-to-peak amplitude of sin wave with high DC offset using grid: 4.5V peak-to-peak amplitude of sin wave with high DC offset using cursor: (cursor1: -2.24, cursor2:2.48V), 2.48V-(-2.24V)=4.70V peak-to-peak amplitude of sin wave with high DC offset using measure: 4.72V

Questions
Are their waveforms that cannot measure properly?
