Figure 4-14: Delay-Trigger Generation
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
incoming trigger signals. You can set Trig_counter to specify
the number of acceptable trigger signals. Refer to Figure 4-15.
In this example, two waveforms are generated after the first
trigger signal. The card then waits for another trigger
signal.When the next trigger signal is asserted, the card
generates two more waveforms.
After two trigger signals, as specified in Trig_Counter, no more
triggers signals will be accepted unless trigger reset command
is executed. For more information on Iterative Waveform
Generation that is used in this example, refer to the next
section.
