The mess is getting bigger!
I upgraded the scope with the 'SDS2000X Plus_1.3.5R5.ADS' file via the web interface. I saw in the system info that the FPGA version went from 2019-xx-xx to something in 2020 and didn't pay further noticed, the scope worked after the update it was late the first day with the scope and I went to bed. The next day I noticed that the instrument part of the web interface did not work. The other parts did work I could send the SCPI command SCOPEID and it returned a number.
One of the last things I did was the upgrade, so I looked a bit better at the system info and noticed that the software version was 1.3.5R3 while I had uploaded the 1.3.5R5 file. I though perhaps only the FPGA part is upgraded via the web interface upgrade, so I did again an upgrade, but now via the USB stick. After this "upgrade" the instrument control of the web interface did work again. But the version number in the system info still was 1.3.5R3, thus I put here the question, because I also could not find the new "Hide" option that was part of the latest release.
Somebody here made the remark about the "AC 1M" in my screenshot, which should be "A 1M", Thus after the upgrade my version was still 1.3.5R3 and thus there was not a wrong number reported, the upgrade was only partial, the FPGA part was upgraded.
So I thought I just try it again with an USB stick. The R5 file loaded again all went normal and then there was the reboot button and I rebooted the scope. But the scope comes now up with the Siglent logo and then hangs, it does not respond to any key, also not the on/off switch. I removed the power supply and tried it a few times, all in vain.
The strange part is, that some parts of the web interface do work. It does respond to a ping, so some processes are started, but it hangs somewhere. My hardware version is reported as 02.00, is that a common version or do I have a different hardware version that is now giving problems?
