Hi!
I need to change the width of the trigger output of the PXI-2529 switch matrix. Th default value of 2 µs is too short for my application.
I tried to use a DAQmx Export Signal Property Node in LabVIEW (from the property selection Events»Advance Complete Event»Pulse»Width Value).
The DAQmx Export Signal Property Node asks for a taskName Input but I don't know how to create this on Labview. I'm using the NI-Switch functions to configure the PXI-2529 switch matrix.
Could you help?
Thanks,
Tom

Why do you use DAQmx functions to configure a NI-SWITCH device?
You should be using functions from the NI-SWITCH function palette…
Have you tried to use niSwitch_ConfigureScanTrigger yet?
According to the specs the trigger output length should be "software selectable"…

Hi GerdW,
Thanks for your answer.
I tried using DAQmx functions based on a previous response in this forum (https://forums.ni.com/t5/Switch-Hardware-and-Software/output-trigger-pulse-width/m-p/2515838)
I already explored all the NI-SWITCH functions palette and did not find any possiblity to modify output trigger width. The niSwitch_ConfigureScanTrigger does not allow to modify this parameter (only its delay and output destination).
Any idea where this "software selectable" parameters could be modified?
Best,
Tomás
