Vertical Settings and Channel
Controls
When you turn a channel trace ON, the Channel flyout menu opens. The
Channel menu page shown (1/2 or 2/2) is always based on the most recent
trace activated.
Choosing Coupling
You can choose one of these input coupling modes:

DC - Passes both AC and DC components of the input signal.

AC - Blocks the DC component of the input signal and attenuates
signals below 10 Hz.

GND - Disconnects the input signal. Use GND coupling to display a
zero-volt waveform. Internally, the channel input is connected to a
zero-volt reference level.
PLEASE NOTE THE FOLLOWING:

If the channel is set to DC coupling, you can quickly measure the DC
component of the signal by simply noting its distance from the
ground symbol.

If the channel is set to AC coupling, the DC component of the signal
is blocked allowing you to use greater sensitivity to display the AC
component of the symbol.
