CURSOR
OFFSET_CONSTANT, OFCT
Command/Query
DESCRIPTION As you change the gain, this command allows you to either keep the
vertical offset level indicator stationary (when Div is selected) or to
have it move with the actual voltage level (when Volts is selected).
The advantage of selecting Div is that the waveform will remain on
the grid as you increase the gain; whereas, if Volts is selected, the
waveform could move off the grid.
Regardless of whether you select Volts or Div, however, the "Offset"
shown in the scope's channel setup dialog always indicates volts.
However, when Div is selected for the Offset Control, the offset in
volts is scaled proportional to the change in gain, thereby keeping the
division on the grid constant.
