Snapshot and Reference Waveform	10. Add a reference waveform by clicking the ‘+’ button, just as you would add a Math channel. Click “Reference” and browse for Channel1.csv that was exported earlier. The channels available for import must only be Channel 1. Click import. Do the same to Channel 2.		The loaded waveform must be the same as what had been saved earlier. This is now a reference waveform.

	11. Add another reference waveform; select allchannels.csv. The channels available for import must now be Channel 1, Channel 2, and Math Channel 1. Select only Math Channel 1. Click import.		The waveform must load the same as what has been saved earlier. This is now a reference waveform.

	12. Add another reference waveform using Snapshot. Increase the amplitude of the waveform in Signal Generator’s CH1. Monitor CH1 of the oscilloscope, then click “Snapshot.”		REF 4 must be added. The waveform must correspond to the signal set in signal generator.
Preferences	13. Click “Preferences” at the bottom of the instrument list, got to the “Oscilloscope” section, and check the box for “Enable labels on the plot”.

Probe Attenuation	17. Turn on “Measurement” and turn on “Display All.” Change the probe attenuation to 0.1X, 10X, 100X, respectively.		As the probe attenuation is changed, the measurement must change respectively i.e. 2Vpp with 10X must be shown as 20Vpp. Labels on the plot as well as the Volts/div must also change.
External Trigger	18. Connect the pins as shown in the Steps Resources on the right.
	19. Pattern Generator’s Configuration:		The interface must look like the image in the “Step Resources” picture on the left. Trace is triggered at rising edge.

	d. Trigger Settings: Internal (Analog) – OFF, External Trigger – ON; Digital: Source – Channel 1, Condition – Rising Edge; Set to Auto (?)
	20. Change the condition to “Falling Edge.”		Trace is triggered at falling edge. When changing the condition, the plot must follow accordingly.
	21. Disconnect T1 and replace it with T0. Change channel source to Channel 2. Repeat steps 18 and 16.		The trace must still be triggered the same as with T1.
Autoset	22. Disconnect the connections from the previous steps. Connect Scope CH1+ to W1 and Scope CH1- to GND. Set these on the Signal Generator: to the following: 2V 5MHz sinewave. Run signal generator and oscilloscope. Click Autoset.		After clicking, wait until the signal/waveform is properly displayed. Trigger must be automatically set to (max-min)/2 - at 50%. Vertical and Horizontal values must automatically be adjusted.
	a. For Channel 1: Sine wave, 2Vpp, 5MHz
	b. Run Signal Generator and Oscilloscope. On the Oscilloscope, click “Autoset.”
	23. Change signal to a 5V, 500kHz sinewave. Click “Autoset” again.		After clicking, wait until the signal/waveform is properly displayed. Trigger must be automatically set to (max-min)/2 - at 50%. Vertical and Horizontal values must automatically be adjusted.
	24. Change the signal to a 10V, 500 Hz sinewave. Click “Autoset” again.		After clicking, wait until the signal/waveform is properly displayed. Trigger must be automatically set to (max-min)/2 - at 50%. Vertical and Horizontal values must automatically be adjusted.
	25. Repeat steps with Channel 2.
Print Plot	26. Connect Oscilloscope’s CH1 to Signal Generator’s CH1+. Connect Oscilloscope’s CH2 to Signal Generator’s CH2. Set these on the Signal Generator:		The expected result must be a pdf file: plotscreenshot.pdf

	c. Press the “Print” button in the top left of the Oscilloscope instrument and save the file in pdf format.
Curve Style	27. On the Signal Generator, set Channel 1’s frequency to 2MHz and Channel 2’s to 5MHz. Monitor both channels in the Oscilloscope. Change curve styles of both channels.		The waveform must correspond to the changes set on the curve style.
Gating	28. Signal Generator’s Configurations:		The peak-to-peak reading must be half the set amplitude. Channel 1 peak-peak = ~5V, channel 2 peak-peak = ~2.5V.
	a. For Channel 1: Sine wave, 10Vpp, 10kHz

Histogram	29. Open the General Settings and turn the “Histogram” on. Change the waveform of both channels to square.		A window must be displayed showing the histogram of the waveform. For this case, the histogram must show the high and low value of the square waves.
ADC Digital Filters	30. Refer to the following document for ADC digital Filter calibration.	Compensation using the digital filters
	31. Set these on the Signal Generator:		The interface must look like the image in the “Step Resources” picture on the left side.

	32. Set the Oscilloscope’s Volt/Div to 1V/Div (high gain mode).		The waveform was adjusted in low gain mode and in high gain mode it must look similar to the step resources picture.
	33. Enable the ADC Filters (Filter 1 Filter 2) from channel settings and set the parameters as follows: Filter 1: TC=60, gain=-0.025, Filter2: TC=9, gain=0.047.		The result must be like in the step resources picture where signals are as follows: Initial signal (green),Filter 1 signal(cyan), cascaded filters signal(orange).
	34. Now if you switch between high gain (±2.5V) and low gain (±25V), you must see a Square waveform in both cases.		The filters must be active in the the mode they were enabled.
	35. Repeat steps 31-34 for Signal Generator and Oscilloscope’s Channel.
