Here is the official .CFG file of Atten CAL scopes. This will place back all Atten settings, including the splash screen.
Let's try this one.
I'm back, luckily nothing serious.
I've installed your .cfg file and, as you said, almost all the ATTEN settings have been restored. In my opinion, there is a digital signature somewhere: in fact, the scope is viewed as "SDS110X" from the pc, as you can see.
After updating to the ATTEN .cfg file, the bug in trace update in slow time/base settings is not resolved. I'm wondering: is this bug related to the SIGLENT version of fw or not? I'm thinking that also other scope models (rebranding) with only 40k memory have this bug, but i can't know their hw version: have they old CYCLONE III / SAT7.820.681H board?
Can the actually installed SIGLENT fw check this (supposed) digital signature of the old ATTEN fw and block the update?
Thanks.
