I'm trying to trigger on the rising edge of an analog signal on ai0 of NI9221 and keep getting an invalid source error in the attached VI. I know the source is currently empty, but when I put a string of cDAQ2Mod3 as the source, this error still appears. I've tried other various combinations of other examples, all with no success. Can you even trigger on the same signal being measured and if so, how would I trigger on the rising edge of the signal on ai0. Thanks in advance.

Hello GSO,
Can you post the error message (an screenshot works fine) to check what it is about. If you try using the examples (Help >> Find Examples >> Hardware Input and Output >> DAQmx >> Analog Measurements >> Voltage >> Cont Acq&Graph Volage-Analog SW Trigger.vi) that come with LabVIEW, does that work?
