Need help with PXI-5422(programming a sync out to PFI0)

[nagalyen]

I am having trouble programming the PFI0 channel on the PXI-5422 fgen board.  I am trying to execute a simple postive ramp signal, but I also need an sync out.  How do I program the PFI0 channel to be a sync output?

Hi,

First of all this would fit better into the Hardware forums.

You can use the "Export Signal Function" to root your SyncOut to a PFI line, just look at the DAQmx help, or if you ar using LabVIEW (I assume so) just look at the VIs context help for more information.

I believe Christian meant to say the FGen export signal, which is also known as a Marker Event, because the 5422 is not supported by the DAQmx driver but rather by the FGen driver.  There is an example that ships with the driver that demonstrates this under Help»Find Examples»Hardware Input and output»Modular Instruments»NI-FGEN»Arbitrary Waveform Generation»Fgen Arb Waveform marker.vi.

This example allowsyou to specify the marker output terminal as well as when the marker fires.  Hope this helps!

@ Doug:  Thanks, this is what i wanted to say! I'm wondering where this DAQmx stuff was comeing from?
