What is this go-no go function in some oscilloscopes and how can I use it?

Question

I have seen some oscilloscopes with this option (go-no go function), but I don't know what it is.

I couldn't find anything about it in my searches.

What is it?

Capture a signal from a known working system, and [the oscilloscope] will draw a mask around it with your specified tolerance. Connect the system under test, and [the oscilloscope] will highlight any parts of the waveform that fall outside the mask area.

This can be used to check for intermittent problems.

Some scopes have a pass/fail output that can be used in automated testing.

I.e. a "design rule check" for your signal: something the EE can instinctively understand. :) – Kaz Dec 10 '13 at 16:47
anybody can see different with their eyes,so why whant to use this function...?... what is sigma number on top picture – firewhale Dec 10 '13 at 20:19
@firewhale: it's explained in the Agilent literature I linked to. *"Six Sigma mask testing"* – RedGrittyBrick Dec 10 '13 at 21:15
