HEREDo you need a picture to go with that?
Try setting the scope to "talk only" if possible to drive a plotter.
I took the plunge and ordered one on Monday - having finally realised that having the time to build something similar was fantasy
Hope that it arrives soon.
Mine arrived last week after a really good attempt by some postal service or other to squash it...
Here is what my HP 54542A sees. I have no way of taking screenshots over GPIB from this scope (and don't feel like spending $59 for software that claims to be able to do it*) so it's a cellphone picture. The scope is set to repetitive with 8 averages.
*no, 7470.exe doesn't work with it.
It should. I don't have one of those but I've had success reports from at least one other user. I have a note from another user with a 54502A that says that the listen-only option needs to be selected in 7470.exe's GPIB menu. Give that a try, maybe, and hit 'w' to make it wait for a plot. What happens if you press the plot button on the 54542A?
Probably not 7470.exe's fault. It's probably some 64bit OS/probably fake 82357B/Keysight libraries 488.2 support problem. 'w' gave an immediate error. I should take the Prologix ethernet adapter home and try it instead.
I think the plot button displayed some message as if it was in progress, then the message went away quietly. I'd set the GPIB settings on the scope to print to a 7470A at that point. Even in this state, 'w' in 7470.exe gave an immediate error.
I have had 7470.exe work before on the same PC with the 8568A SA, but I don't recall which adapter I used.
For now, sneaker-net with the floppy drive is working.

Looks good.
That's a (very) old version of 7470.exe, but given the density and layout of the label text, it might actually look better than the higher-fidelity vector text renderer in the current build.
A question - is it better to look at an equivalent time sample mode or single shot mode for the rise time/fall time measurements?
Maybe I missed it, but which output driver (the one branded AJK BAA) are you using in the latest revision?
I received mine today!
Are all the measurements being done here 10%/90% or 20%/80% ?

I also assumed the pulser supplied trace showing a rise-time of 49.2ps for the unit as correct as I do not know the specs of the measuring instrument. I assume it is much better than my old stuff
