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:
(1). Press the CH1 MENU button and call out the CH1 SETUP menu.
(2). 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.
The waveforms are shown as Fig.15 and Fig.16.
