ACSELERATOR QuickSet displays the Event Waveform dialog box and the
event oscillogram (similar to Figure 6.14 and Figure 6.15).
When viewing the event oscillogram, use keyboard function keys to measure
the time of oscillogram occurrences. These function keys and related
functions help in event analysis.
➤ <F2>: go to trigger
➤ <F3>: Cursor 1
➤ <F4>: Cursor 2
The display shows the time difference between Cursor 1 and Cursor 2.
To see high-accuracy time-stamp information on the event oscillogram, click
the Pref button at the bottom of the oscillogram and select Time (under Time
Units, Starting/Ending Row); click OK. Click on any point in a graph to
observe the Event Time in microseconds of that data point at the bottom of
the oscillogram.
