Chapter 2 Vertical System Setting

To Specify the Channel Coupling

Set the coupling mode to filter out the undesired signals. For example, the signal
under test is a square waveform with DC offset.
When the coupling mode is "DC", the DC and AC components of the signal under

test can both pass the channel.
When the coupling mode is "AC", the DC components of the signal under test are

blocked.
When the coupling mode is "GND", the DC and AC components of the signal

under test are both blocked.
Press CH1  Coupling and turn the multi-function knob
coupling mode (the default is DC). You can also press Coupling continuously to
switch the current coupling mode. When different coupling mode is selected,
different coupling label is displayed in the channel status label at the bottom of the
screen, as shown in the figure below. When "AC" coupling mode is selected, the
character "AC" below CH1 is illuminated.
