Selecting AC-Coupling
Use AC-coupling when you wish to observe a small AC
signal that rides on a DC signal.
Open the SCOPE INPUTS menu.
Highlight AC.
(4x)
Accept AC-coupling for INPUT A.
Reversing the Polarity of the Displayed
Waveform
To invert the input A waveform, do the following:
Open the SCOPE INPUTS menu.
Select NORMAL (of INPUT A).
Highlight INVERT.
(3x)
Accept inverted waveform
display.
For example, a negative-going waveform is displayed as
positive-going, providing a more meaningful viewing
perspective in some cases. An inverted display is
identified by trace identifier
A
on left of the waveform
area.
