Is there also a fix available for the SDS1102X ?
I'll do some research with an X I have here and ask the factory if a similar fix is needed.
Thank you.
Now I wonder, will they honor warranty on this issue?
I don't know how. It will take longer to do the paperwork, packaging and despatch than the rework.
One might ask the same of other manufacturers that have this same issue......you can see by the replies there are some ........... and how many other members are reluctant to share their 10x compensation mismatch experience.
It could be more common than we think. Good video topic for Dave.
The X-E is quite simple to get apart although you must engage brain so to not damage anything but the soldering is a little tricky as it's inside the shielded input box. The 4pF cap is paralleled alongside an existing cap, the value of which I should've measured when I had my demo unit apart. Grrrr. Will measure it later.
Then the scope must be partially reassembled and powered on to check the waveform and maybe adjust the trimmers. I think the job can be done in ~40 mins providing all tools are ready and at hand. (challenge for Defpom
)
All that's needed to disassemble X-E is #2 Phillips, medium flat blade screwdriver and 16mm or 5/8" AF Ring spanner or deep reach socket or even an adjustable spanner will undo the BNC nuts. (they're not recessed
)
Four connectors need to be unplugged, display flat cable (locking connector and fabric adhesive tape), front panel ribbon cable (locking connector) fan and PSU.
Undo the 3 BNC nuts and then you have the mainboard free to remove the input shielding cover and solder the caps in. The mainboard is covered in fragile components and need be handled with care, some antistatic sheet foam will be good to avoid any damage.
