Trigger Modes
Post-Trigger Generation
Use post-trigger generation when you want to generate a
waveform right after a trigger signal. The number of patterns to
be updated after the trigger signal is specified by UC_counter*
IC_counter and is illustrated in Figure 4-13.
Figure 4-13: Post-Trigger Generation
Delay-Trigger Generation
Use delay-trigger when you want to delay the waveform
generation after the trigger signal. The delay time is
determined by DLY1_counter, as illustrated in Figure 4-14.
The counter counts down on the rising edges of DLY1_counter
clock source after the start trigger signal. When the count
reaches zero, card will start to generate the waveform. The
DLY1_counter clock source can be selected via software
application using the internal 80 MHz timebase.
