Having read the 39 pages of this topic twice I began to understand what was required.
1) Telnet access is required to do anything.
2) There is a basic option to rename replace 2 files: "nsp_data_b", and "NSP_system_info.xml" with custom versions.
- this gives you an options fully loaded SSA3021x (or even SSA3032x) BUT the serial no. is set to SSA_XXXXXXXXX
3) The updated procedure is more complicated and requires switching off the running "ecomb" program on the SSA and running "ecomb8" instead.
You should first replace the "nsp_data_b" with the version from version 1.2.8.1 of the Firmware.
The "ecomb" renamed as "ecomb8" is also obtained from this firmware.
The former has been posted on this forum but the later has never been.
There is an extraction tool to obtain these files from the 1.2.8.1 FW (V01.02.08.01) but this is not reliable and has been withdrawn.
The "NSP_system_info.xml" also needs to be replaced with a customised version containing the users serial number (if they want to keep it).
This method seems to be the best in the long term but seems unavailable unless someone is kind enough to post a tested version of the "ecomb" from 1.2.8.1
There is also something about the RBW being reduced by the simpler hack?
OK. Please correct the above if I have misunderstood.
Now to my attempts.
As my machine arrived with version 1.2.9.3a I was faced with a problem of no Telnet.
I realised there was a risk of using the Telnet.ADS but it seems that it was a risk with later software (hopefully!!). I gave it a go. It was no go. It went to 60% loaded but no telnet. I switched off using the power button and held my breath - rebooted as normal. Phew!
Without this telnet option working my only other thought was to try the 1.3.9.7 (with Telnet / Webserver ) version posted above. This loaded although I had to do a reset before it was shown (even though the machine had power cycled). Seemed to be all ok on the machine.
I found that the webserver was working (very well actually).
The telnet was a different matter. I had got the "Welcome to SCPI instrument Siglent SSA3021X" login with port 5024 before the upgrade and this still worked.
Port 5025 also continued the telnet session but "returns" just produced a blank screen.
I did a port scan and found these ports open 80(http), 111,897,5024,5025. 10101 and 800 were not.
Port 111 opened (and stayed open) but like 5025 produced a blank screen.
Port 897 immediately closed on starting (I was using PUTTY in windows 10).
Well, thats all the info I have I'm afraid. I'm a bit stuck now. If I had got into telnet my plan was to copy all the files, then try and downgrade to 1.2.8.1 and copy all the files there. I was going to compare the two "ecomb" files to see if the downgraded software would give me the desired version for the complex hack?? I may even have been able to do it there and then. But ofcourse this depends on if the downgrade worked.
I would appreciate any thoughts, particularly in relation to the 111 and 897 open ports. Wonder what is going on there?
Thanks.
