Rohde & Schwarz RTO1024 upgrade ??
TRN:
The GB receivers are located on the mainboard and are R&S custom made BGA ASIC's. They are unobtainable, no datasheets available, so if your scope has this defect, then you have only a few options to get this fixed.
1) R&S standard repair, which costs around 5,000 USD.
2) try to obtain a second hand mainboard. I have been looking for one for more than 3 years, but with no luck. Nobody appears to have these spare on the shelf
3) If you are lucky, the problem is not with the ASIC's, but with the BGA soldering, so try to locate a shop, which can x-ray the mainboard to see if there are some suspect solder connections under the BGA's
4) if this is the case, you will need to source a company which can rework / reflow the board.
As far as option 4 is concerned, be careful which company you choose. I had my mainboard reworked, by a company, with as result that the board warped, lost a few 0201 resistors and/or capacitors.
Prior to sending the board for repair, Channel 1 & 2 were working fine, but after the "repair attempt none of the channels work anymore.
So be warned!

Hi myhobo,
I have firmware version 2.50 (Setup_Rto_V25027_x86.exe size 366.043KB)
myhobo:
This is a small problem. I can help you fix it. I can do it remotely until you don't need to mail it.It can't be that the ASIC chip is broken. R&S machine design is very good. The self-protection function is very perfect, so it can't be that there is something wrong with the big chip.
myhobo:
The solder used by R&S is high-temperature lead-free solder. The plate area is small, and the possibility of virtual welding due to deformation is very small, so there is a problem in the direction of analyzing the problem. I have repaired more than a dozen machines of this series, and I know rto very well.
myhobo:
Friends of the forum,I used the service password to enter the background to flash the mainboard program, but after waiting for a long time before the flashing was finished, I restarted my machine. After restarting, my machine fan kept turning wildly, and the startup software reported an error "failed to open driver(RTODrv.sys)". I couldn't enter the normal mode or service mode, and I could only enter the simulation mode. Who can help me? Thank you.
