Delay Trigger Acquisition
Use delay trigger when you want to delay the scan after a trig-
ger signal. The delay time is determined by the Delay_counter,
as shown in Figure 4-3.
The counter counts down on the rising edges of Delay_counter
clock source after the trigger signal. When the count reaches 0,
the DAQ-/DAQe-/PXI-2502/2501 card starts to perform the
scan. The acquired data length is equal to the:
(number_of_channels_enabled_for_scan_acquisition
) * PSC_counter
The Delay_counter clock source can be software selected from
internal 40 MHz Timebase, external input (AFI-1), or General
Purpose Timer/Counter Output 0/1.
