SJL-Instruments:
As promised, we have released v2.6.0 of the software which adds jitter analysis. Measurement markers have been added, and more measurements are now available in point mode. The manual has been updated to revision H13. Image attached.

We've recently come up with a better algorithm for the dual-comparator version that offers a quadratic speedup. In theory this should reduce the Nmin requirement for eye diagrams by a factor of 300. This would allow capturing a PAM4 eye in 10 seconds, and a two-level eye in <1 second, without any increase in trigger rate. This also lets us avoid the pretrigger requirement. Now to put this into practice...

Tried out the latest software and the first thing I noticed was when I change to color grading, the plots background now turns solid white.   Turning off the readouts, changing the scaling and CDF options has no effect.   With vectors enabled, it appears normal.
SJL-Instruments:
This is due to graphics-card-specific OpenGL implementation details. This prerelease should fix the problem:

Is this the machine you're testing on? We'll build one with the same specs for future QA checks.

Yes.  I suspect the other machine I listed would have the same problem if you would like me to try it.   Updated software does solve it. 

Looking at task manager, does seem to require a bit of processing on this old PC.

If you have the time, this would be helpful information to know. Good that the fix addresses the problem.

We'll improve the caching structure and CPU usage in the next update. We've put just enough time into optimizing the software for it to run smoothly on Windows tablets - but there's always more that can be done.
