If the Reference trigger is asserted before the required number of pretrigger samples are acquired, it is ignored. This node is valid only for acquisition sessions.
Inputs/Outputs
session in
Instrument session obtained from the Initialize Acquisition Sessionnode, the Initialize Generation Sessionnode, or the Initialize External Calibrationnode.
error in
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Default value: No error
source
The specified trigger source.
You can choose PFI <0..3>, PFI <24..31>, PXI Trigger Line/RTSI <0..7>, PXI STAR Line, or PXIe DStarB.
edge
The specified edge to detect.
| Rising edge | 12 | The trigger asserts on the rising edge of the digital signal. |
| Falling edge | 13 | The trigger asserts on the falling edge of the digital signal. |
Default value: Rising edge
pretrigger samples
The number of pretrigger samples the device must receive before the Reference trigger is acknowledged.
Default value: 500
session out
Handle that identifies the session in all subsequent node calls.
The session out parameter is obtained from the Initialize Acquisition Sessionnode or the Initialize Generation Sessionnode.
