Some reverse engineering of the front end...

Do you want to proceed with a Pspice simulation to estimate the impact of input resistor removal ?
If so you should gently unsolder all SMT capacitors and take precise value measurements ... :D

Dear WIM, I have a favor to ask you : could you gently check how the first three E2PROM pins are connected (A0,A1,A2) ?
If I look at Picoscope board PCB image I can spot a second unpopulated E2PROM footprint (also present in 2000A series) with readable address pins configuration but I wonder at which address is set the mounted E2PROM.

In the mean time i was looking to Picotech webshop for one 3203D ... just to find out that chip shortage incidentally hits only "low cost" SKUs.
The cheapest model is an 3205D (2CH 100MHz 1GS/s) at whopping price of 979 euros plus taxes, that is the same cost of SDS2104X-Plus and I even paid less my Rigol HDO1074 ...

I recommend looking at other vendors. They do not seem to save the best stock for themselves.

Looked everywhere, beyond the attached list, it seems that 3203D, as well as other models with midrange prices, are vaporized or went in another dimension.
Only jewelery pieces are still available, it smells it's not matter of chip shortage ;).
