When all lab work is completed, you will be asked by a tutor to:
Set up a 3 V p-p sinusoid at 3 kHz, with 3 V DC offset. Display the entire waveform on the DSO with the 0 V reference set to the middle of the display on Channel 1. Show only the AC component of the waveform on Channel 2. Use the DSO Quick Measure feature to measure the average, peak-to-peak and RMS values of the waveform on Channel 1.

Change the sinusoid amplitude to 10 mV p-p. Set up the DSO to get a stable, noise-free (averaged) display.

Change the sinusoid amplitude back to 3 V p-p, remove the DC offset and set the frequency to 3 Hz. Apply the FG signal to Channel 1 of the DSO with DC coupling, and to Channel 2 of the DSO with AC coupling. Measure the phase difference.

Set up a triple power supply to provide +5 V, +10 V and +15 V with respect to earth. Use the DSO to observe and measure each voltage.
