Extract the delta x value of a signal in Labview

[dadest100]

Hi guys, 

I recording a signal using the "Write labview measurement file" tool. When it the file gets saved it has a delta x (time) and a value. I need to be able to use this delta x in real time to monitor the quality of my signal. If this interval between datapoints is to high then I will classify the signal as a poor signal. 

How can I extract this delta x from my signal in real time??

If you read the data as an wfrm datatype you can get the dx property.

Or you use the actual samplerate property of DAQmx and use 1/x 😉

or ...
