3. If the option is available on your oscilloscope, you can set up the
oscilloscope to optimize either Analysis (acquisition and calculation
speed) or Display (update rate/speed) using the buttons provided on
the Optimize For section of the dialog.
Available choices are presented as a spectrum with highest values at
Analysis and Display extremes.
Select one of the buttons for the desired performance optimization.
Example reasoning for Analysis optimization would be its persistence
or averaging usefulness. In such a case, giving higher priority to
waveform acquisition at the expense of display update rate makes
practical sense.
Acquisition
Access the Acquisition preference settings in the following manner:
The Acquisition dialog (Trigger Counter Setting not available on all models).
Numbered sections on this dialog 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.
