Differential Offset
The differential offset function can compensate a DC voltage applied between the
positive (V
p
) and the negative (V
n
) input terminal at the probe tip. Setting a differ-
ential offset compensation in DM measurement mode is directly visible on the
oscilloscope screen as a voltage offset of the measured waveform.

Common Mode Offset
The common mode offset function can compensate a DC voltage applied to both
input terminals at the probe tip (referenced to ground). Setting a common mode
offset compensation in CM measurement mode is directly visible on the oscillo-
scope screen as a voltage offset of the measured waveform.
