Hi Ulrich,
I think the noisy amp was the Max4017, but I have to check.
Great job on the Plotter update! Can't stress how helpfull that tool is.
Thanks,

Hi Said,
may I ask WHICH Maxim amp you tried, just for a new collector's item in
the list od DOs and DONTs of timing?
BTW: A corrected PLOTTER version is availbale with centered main window,
no changes otherwise.

Ulrich

Yes, it works fine.
Be aware that very few designed for video distribution amps are
isolated so you risk groundloop
