Overlay (Cl,C2)
wh
t a we have been displaying so far in this section are examples using
just single channels. These examples display a single input channel in
each waveform display.
I---
Suppose you wanted to take the signal from CH 1 and compare it to the
signal from CH 2. The easiest way to do this would be to put both
waveforms on the same waveform display, or overlay the waveforms.
1. Select CH 1,then select Modify waveform. Select Cl,C2, then
touch the RUN key. CH 2 is now overlayed on CH 1 in the top
waveform display.
2. Select the s/Div field and change the sweep speed to 5 ns/div.
This will allow us to see the overlayed waveforms easier. The
display should now look like the figure below.

Note u
To get a better display of the two waveforms overlayed, use an extra
1
ong cable on one of the inputs. This will delay one waveform.
