Taking the Channel 1 for example, the measured signal is a square wave signal
containing the direct current bias. The operation steps are shown as below:

Press the
F1
menu selection button and select the Coupling item as “AC” to
set the channel coupling as ac mode, under which the direct current
component in the signal will be blocked.
Then, press the
F1
menu selection button again and select the Coupling item as
“DC”, setting the channel coupling as dc mode, under which both dc and ac
components in the signal will be unblocked.
