VTL\VTH Measurement

[Janit]

Hi All,

I want to do VTL\VTH measurement for one of my IO device . In this what I will be doing is superimposing two waveform and will be finding out the crossover points.

I want this value of crossover to be taken by doing it on multiple cycles and then driving the average value out of it.

Can somebody suggest me how to so this.

thanks

Janit

Janit,

There are actually quite a few discussion forums where this issue has been discussed. I've linked a couple here and here to get you started, but I would recommend searching the discussion forums to find more. The bottom line is that there is no one function that you can call in LabVIEW to do this, but you can build one yourself (or use one that has already been posted here in the forums). Also, one bit of new information to add to this topic is that if you are using LabVIEW 8.0, there is MathScript function called "intersect" that can be used to do the trick quite simply. I've included a link to the help documentation on that MathScript function here and a link to the general MathScript page here.

Kind Regards,

[Janit]

Thanks Sulzer for the help
