Vertical Settings and Channel Controls
When you turn a channel trace ON, the Channel menu opens. The Channel
menu page shown (1/3, 2/3, or 3/3) 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.
NOTE:

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.
