Channel Coupling

The undesired signals can be filtered out by setting the coupling mode. 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

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.
