PCIe 6321 - Error 200077

[NE_PKT]

At the present state I have tried several examples provided in the forum over the last three days. But I was not able to modify one of them to get it working as desired.

I would like to measure a voltage on (lets say Dev/ai0) while the trigger channel (e.g. Dev/ai1) is above a certain level. Unfortunately the trigger signal is not a digital trigger, so I need to use an analog trigger signal.

Is it possible to use the PCIe 6321 taking one channel as a trigger channel and logging a measured voltage from another channel (Dev/ai1)?

Using the DAQmx functions straight forward causes an 200077 error.

Hi NE_PKT,

as you already see in the Error Message your PCIe-6321 don't support analog triggering.

In my Opinion its no 'easy' way to make this work. You can solve this problem of course programmatically. Read out both channels and make a compare in LabVIEW and just write or save data your interested in.

To find a appropriate Example for your hardware you can select the hardware in the Example Finder to see witch Examples works with your hardware.

Hope I can help
