Acquisition
Access the Acquisition preference settings in the following manner:
The Acquisition dialog. Trigger Counter Setting is not available on all models.
Numbers on the image correspond with the following explanations.
1. On the Offset Setting constant in area of the dialog, touch either the
Div or Volts button.
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; whereas, 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.
2. On the Delay Setting constant in area of the dialog, touch either the
Time or Div button.
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; whereas, 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.
