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 to select the desired
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.
