Hi,
I am playing around with the DSA 602A and I am rather confused by histograms. I could create them, but I cannot imagine a way to make them useful (the manual does not say what they are for).
Surely this is a limit of my limited knowledge... would someone help me ?

Thanks

Gianni

If we're talking about the same thing, it's an overlay of multiple waveforms. What it shows is how long the transition takes and how uncertain it is (in time), and where the stable part of the waveform is.

One use is in communications where you measure the jitter of the channel (it's called an eye diagram there, IIRC). It is a good predictor of how well you can extract stable data from the stream. If there's no stable eye, forget the data.

so you get an indication that shows:

UNSTABLE...... STABLE....... UNSTABLE...... STABLE.......

and you want to sample the data in the middle of the "stable" area.
