Post-Trigger or Delay-Trigger with Retrigger
Use post-trigger or delay-trigger with retrigger when you want
to generate multiple waveforms with respect to multiple incom-
ing trigger signals. You can set Trig_counter to specify the
number of acceptable trigger signals.
Figure 4-11 illustrates this example with an Iterative Waveform
Generation. Refer to next section for details. Two waveforms
are generated after the first trigger signal. The board then waits
for another trigger signal. When the next trigger signal is
asserted, the board generates two more waveforms. After
three trigger signals, as specified in Trig_Counter, no more trig-
gers signals are accepted unless software trigger reset com-
mand is executed.
NOTE Start Trigger signals asserted during the waveform gen-
eration process are ignored.
