4.6.4 Delay-trigger Acquisition
Use delay-trigger acquisition to delay the data collection after the
trigger event, as illustrated in Figure 4-14. The delay time is speci-
fied by a 32-bit counter value so that the maximum delay time is
the period of TIMEBASE X (232 - 1), while the minimum delay is
the period of timebase.
