Acquisition
Offset Control
As you change the gain, this control 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 remains on the grid as you increase the gain. If Volts
is selected, the waveform could move off the grid.
NOTE: Regardless of whether you select Volts or Div, the Offset shown in the
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.
Touch Utilities  Preferences from the menu bar.
Touch the Acquisition tab.
Under Offset Setting constant in:, touch either the Div or Volts button.
Delay Control
As you change the timebase, this control allows you to either keep the
horizontal offset indicator stationary (when Div is selected) or to have it move
with the trigger point (when Time is selected). The advantage of selecting Div
is that the trigger point remains on the grid as you increase the timebase. If
Time is selected, the trigger point could move off the grid.
NOTE: Regardless of whether you select Time or Div, the Delay shown in the
timebase setup dialog always indicates time. However, when Div is selected
for Delay In, the delay in time is scaled proportional to the change in timebase,
thereby keeping the division on the grid constant.
