Hi.
I have bought MSO5074 (hw. version 1.00) some time ago, and from the beginning I have overshoot undershoot issues, as well as square signal from arbitral generator has also 20% over and undershoot. After applying newest firmware 01.01.04.08 and lfcal.hex from mable and running self calibration they are still there. After applying mable's lfcal.hex they vanished from 1st channel, almost vanished from second channel, but they are still on 3rd 4th channel. Do You think i should send it to Rigol?
Please look at the screenshots.
