View Backplane PXI Trigger Bus?

[jvavra]

I'm working on a project where I need to route a data marker event from a PXI 5402 function generator to a PXI 2521 via te PXI trigger bus on the backplane. I'm having a bit of trouble coding it, and it's tough troubleshooting it as I can't tell where the event marker is/is not getting to. Is it possible to actually view the PXI trigger bus somehow? Can I wire it out so I can throw a scope on it? 

Thanks!

Hi,

Can you please tell which is the chassis you are using, Is it the data marker a trigger? What is it exactly that you are trying to do? 

Regarding your last question you can't wire out the trigger bus, this is internal an internal connection, please read the following documents, it might help one is regarding reserving the PXI trigger bus (1) and this one discuss the PXI trigger functionality (2)

Hope it helps.

Have a wonderful day.

Luis,

I am using a PXI 1033. The data marker is indeed supposed to be a trigger; I'd like to use a PXI 5402 function generator and route a one-shot square wave to some PXI 2521 switches so that I can precisely control some linear actuators wired to the switches by varying the pulse widths. I'm trying to get a data marker to follow the rising and falling edges of the square wave generated by the function generator.
