timing measurements of AD data

I would like to take 60Hz low voltage data with a NI 9215 AD - then take timing measurements of a glitch / pulse imposed upon that input 60Hz.

I am unclear as to how to parse the data to accomplish a timing measurement.   I could supply a trigger signal on a second channel of the 

NI9215 if needed. 

Looking for sample code vi or suggestions.

Hello,

Thank you for posting to the NI forums. I think that you should be able to get a good start by looking at some of the LabVIEW examples that incorporate triggering. You can access the examples by opening LabVIEW and going to Help>>Find Examples. From there you can go to Hardware Input/Output>>DAQmx>>Voltage>>Analog Measurments. You can view a description of each example on the right side of the screen by clicking on an example. I would start by looking at the example called Cont Acq&Graph Voltage-Analog SW Trigger.vi. This should at least get you going with the correct logic as far as triggering off a certian voltage level.
