Rigol just released a version of the 1.03.02.02 on the US website. When you do the actual download, the file name is MSO5_FW_V1_1_4_4, the upgrade instruction.txt file is still gibberish, likely in a different language. For the actual GEL file, the checksum was exactly the same as the one in the Chinese site which disappeared earlier. They never had a professional discipline in managing firmware update when the MSO5000 came out, sadly this trend continues years later.
Here is the change log, also the same as before:
v00.01.03.02.02 2023/01/04
- Add shortcut button and VNC remote function
- Waveform, cursor movement, gesture operation vertical and horizontal gear switching speed optimization
- Cursor optimization: cursor jump optimization, ZOOM area and main time base cursor linkage, etc
- The color of the CH4 waveform is modified, and the brightness of the waveform is improved
- ZOOM mode optimization: mask color adjustment, switching speed, area movement optimization
- SCPI instruction response speed optimization: reset, measurement, waveform read instruction response optimization
While the file is the same as before, at least now you are downloading this patch from the official firmware download site. So hopefully we will get some support from Rigol in case the upgrade fails.
Until someone come up with a new patch file, you will lose the "enhancements" if you apply this firmware. Let's hope this wonderful community can come up with a new patch file soon to share with everyone.
