voltage histograms

[sjl006]

Hi, I am using NI's example of generating a BPSK signal (with some random noise) and demodulating it with the NI example. With the resulting eye diagram (one eye in the middle), I want to create a voltage histogram, but I'm not sure where to start. I tried using the NI-Scope's multi fetch vi and I dont think i got the correct histograms b/c it wasn't using the eye diagrams waveforms. Any advice or direction to any relevant thread is greatly appreciated.

Thank you,

Sammy

Sammy,

I found this tutorial on our website that talks about both time and voltage histograms and gives LabVIEW examples. I think this will give you the information you're looking for. Good luck and have a great day!
