The Sequencer menu includes a Pre-trigger xx% function which lets you
set the percent of data to be captured before and after the triggering event.
This percentage is set by default to 50%. For more details see “Set
Trigger” on page 81
The Sequencer definition dialog box shown Figure 72 displays the programmable
states as follows:
S0 The starting state, displayed always.
S1 - S31 These states can be viewed and programmed two
at a time by using the scroll bar on the right side
of the screen.
Tag and Discard Tag and Discard allows the user to delete a portion of the capture memory.
Setting Tag places a marker in capture memory and setting Discard causes
the deletion of all captured data between Tag and Discard.
Click the ellipses after If [Event_A occurs] ”...” and choose Tag_Event at the point
after which you expect a result. Then click the ellipses after ElseIf [Event_B occurs]
”...” in the state where you expect the result and choose Discard. Data will be
discarded between the last Tag_Event set and the Discard set.
To program the sequencer with a menu form click the Form button in the
