Solution
Natively the NI-SCOPE driver does not support a timestamp type trigger (such as NI-DAQmx). It can be implemented using a timing card such as the PXI-6682H.
The idea is to generate a hardware trigger on the PXI backplane, such as on the
PXI_Trig0, and use it to trigger the fetch/acquisition on the NI-SCOPE board.
You can use the example found in Help >> Example Finder >> Hardware Input and Output >> Timing and Synchronization >> Time-based >> Generate Event VI to generate a trigger at certain time, selecting the proper Start Time Delay (Seconds). Select as Output Terminal PXI_Trig0. This value must be the same of the digital trigger input in the NI-SCOPE task.
In the acquisition task with the NI-SCOPE you must insert the
niScope Configure Trigger VI block and insert the same value that has been inserted in
Output terminal (in this case
PXI_Trig0)
