Dc Channel Coupling; Ground Channel Coupling - Agilent Technologies U1602B User's And Service Manual

3 Using the Scope Functions

DC Channel Coupling

In DC coupling mode, both AC and DC components exist in the input
waveform to the instrument. DC coupling is useful for viewing waveforms
as low as 0 Hz that do not have large DC offsets. The
shown at the top left of the status line. See Figure 3- 7 for DC channel
coupling.

Ground channel coupling

In GND coupling mode, the waveform is disconnected from the
oscilloscope input. The
