ni 5122 export signal

[joohnoon]

Hi, all.

I am developing my own window application and thus using niScope API

My system accepts external digital trigger signal from a function generator 1 (DS345)  through PFI line 0

and needs to import a delayed version of the signal to function generator 2 (also DS345). I tried to do this

by using the function niScope_ExportSignal and setting the parameter signal to NISCOPE_VAL_REF_TRIGGER.

I tried to observe the pulses generated on oscilloscope each time  trigger is detected but I couldn't.  Can anybody help me?

Joohnoon,

If you've configured your NI-Scope acquisition to look for a reference trigger (not a start trigger) on PFI 0, you can then also configure the session to route the reference trigger out to PFI 1.  After the session is initiated and the board is waiting for a reference trigger, any subsequent reference pulse on PFI 0 will cause a "reference trigger" to occur and a pulse will occur on the output PFI 1.  You can also route the trigger signal to your PXI backplane.

I hope that this is helpful.  Please let me know if you have any follow-up questions.
