Delay-trigger
This trigger acquisition is used in applications if you want to
delay the data collecting process after a specified trigger
event. The delay time is controlled by the value, which is
pre- loaded in the Delay_counter (32- bit). The clock source is
the Timebase clock. When the count reaches zero, the
counter stops and the board start to acquire data. When the
internal 48 MHz is set as Timebase clock, the delay time is
in the range of 20.8 ns to 89.47 s. If the Timebase clock is
from external clock (48 MHz to 1 MHz), the delay time can
be varied by user's setting.
