$'$& $, &RQW 6FDQ FRQ¶W
0:Scaled Return scaled voltage data only (default setting). The binary data array appears
empty.
1:Binary Return binary data only. The scaled data array appears empty.
The VI executes faster if you select this value, because the VI does not perform scaling.
TRIGGER INFO TRIGGER INFO configures the analog input triggering mechanism
on the specified Device Handle.
Trigger Mode (0:disabled) Trigger Mode is a numeric value that sets the
hardware trigger operation mode. The available options are:
0:DISABLED All triggering is disabled.
1:ABOUT_TRIG Collect (N) data points before and (N) data points after a
trigger. Supported by A/D's ABOUT TRIGGER capabilities.
2:POST_TRIG Collect (N) data points after a trigger. supported by A/D's with
DMA, Interrupt or FIFO capabilities.
3:PRE_TRIG Collect (N) data points before a trigger. Supported by A/D's
ABOUT TRIGGER capabilities.
4:SCAN_TRIG Collect 1 data point for each channel after each trigger.
Supported by A/D's SCAN TRIGGER capabilities.
The default Trigger Mode is 0:DISABLED
Trigger Source (0:disabled) Trigger Source is a numeric value that sets the
hardware triggering source. The available options are:
0:DISABLED All triggering sources are disabled.
1:EXTERNAL Trigger the acquisition from an external event. Supported by
A/D's with DMA, Interrupt or FIFO capabilities.
2:CTR1 On-board counter 1 triggers the acquisition. Supported by A/D's with
DMA, Interrupt or FIFO capabilities.
3:CTR2 On-board counter 2 triggers the acquisition. Supported by A/D's with
DMA, Interrupt or FIFO capabilities.
The default Trigger Source is 0:DISABLED
