Export Signal
Routes signals (clocks, triggers, and events) to the output terminal you specify. Refer to your device documentation for valid signal destinations.
If you export a signal with this node and commit the session, the signal is routed to the output terminal you specify. If you then reconfigure the signal to have a different output terminal, the previous output terminal is tristated after the session is committed. If you change output terminal to Do Not Export when you commit the session, the previous output terminal is tristated.
Inputs/Outputs
session in
Instrument session obtained from the Initialize Acquisition Sessionnode, the Initialize Generation Sessionnode, or the Initialize External Calibrationnode.
signal identifier
The signal being exported.
You can select Script Trigger 0, Script Trigger 1, Script Trigger 2, Script Trigger 3, Marker 0, Marker 1, Marker 2, Marker 3, or None.
signal
The signal you want to export.
| Sample Clock | Device Sample clock. | |
| Reference Clock | Device Reference clock. | |
| Start Trigger | Device Start trigger. | |
| Reference Trigger | Device Reference trigger (dynamic acquisition only). | |
| Advance Trigger | Device Advance trigger (dynamic acquisition only) | |
| Pause Trigger | Device Pause trigger (dynamic generation only). | |
| Script Trigger | Device Script trigger (dynamic generation only-requires signal identifier to describe a particular Script trigger). | |
| Stop Trigger | Device Stop trigger (dynamic generation only). | |
| Data Active Event | Data Active event (dynamic generation only). | |
| Ready for Start Event | Ready for Start event. | |
| Ready for Advance Event | Ready for Advance event (dynamic acquisition only). | |
| Marker Event | Marker event (dynamic generation only-requires signal identifier to describe a particular marker). | |
| End of Record Event | End of Record event (dynamic acquisition only). | |
| Onboard Ref Clock | Device onboard Reference clock (PCI devices only). |
output terminal
The terminal where the signal is exported.
| Do not export signal | The signal is not exported. | |
| PFI 0 | The signal is exported to the PFI 0 front panel connector. | |
| PFI <1..3> | The signal is exported to PFI <1..3> on the DDC front panel connector. | |
| PXI Trigger Line/RTSI <0..7> | The signal is exported to PXI trigger line or RTSI trigger line. | |
| CLK OUT | The signal is exported to the front panel CLK OUT connector. | |
| DDC CLK OUT | The signal is exported to the DDC CLK OUT pin on the DDC front panel connector. |
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
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.
error out
Error information.
The node produces this output according to standard error behavior.
Unconfiguring signal routes
Any routes created within a session persist after the session closes to prevent signal glitching. To unconfigure signal routes created in previous sessions, set the reset instrument parameter in the Init Generation Sessionnode or the Init Acquisition Sessionnode to True or use the Reset Devicenode.
