3. Use the lower REF A option button to turn the reference waveform
on or off.
This also shows or hides the reference waveform from the grid
display area. Now, you can make adjustments to your waveform
leaving the REF A trace intact for comparison.
4. Press the middle REF A option button to switch from REF A to REF B.
Both the middle and lower REF A option buttons now show labeled
as REF B and adjustments can be made for the additional reference
waveform.
5. Use the Save option button to save your reference waveform for
comparative analysis at a later time.
Note: Keep in mind that the reference waveforms are stored in
volatile memory. This means that REF A and REF B are temporarily
stored until the next time the oscilloscope is shut down.
