NI-5133 won't acknowledge PFI as channel to trigger from

[Wolley]

Hello,

trying to use an NI-5133 Scope to read two channels, triggering off an external signal. Labview 2011, Scope 3.9.4

I figured based on documentation that it would be no reading a trigger in on the PFI line (labelled PFI1 on the hardware, I still don't understand why it wouldn't be PFI0). Anyway, I tried using the niScope Configure Trigger block, and it will only let my choose between channel 0 and channnel 1 returning an error if I try to tell it to use the scope. I tried an alternative approach I found after perusing forums and that didn't work either, also returning an error:

niScope Initiate Acquisition.vi:1<ERR>Source terminal to be routed could not be found on the device.

Make sure the terminal name is valid for the specified device. Refer to Measurement & Automation Explorer for valid terminal names.

Source Device: NI_Scope
Source Terminal: PFI0
Destination Device: NI_Scope
Destination Terminal: StartTrigger

Status Code: -89120

Any advice on how I can get this to work triggering off the PFI line would be much-appreciated.

I've attached my VI, I know it is probably pretty poorly constructed but I am very new to Labview.

Thanks,

Wolley

Hello Wolley,

What I would suggest is that you try running the NI SCOPE Soft Front Panel. This will allow you to verify the functionality of the hardware without adding the software variable. It can be found under Start>All Programs>National Instruments>NI-SCOPE.

You can configure it to run with a trigger off of PFI1 and give it a try. You should be able to acquire from both CH0 and CH1.

Hope this helps.
