Scanning 'key.txt' failed: No keys
I have attached the key.txt I generated with HxD for reference.

This file contains some invalid chars and is too short. Maybe the *IDN? response was distorted during transmission or UltraSigma doesn't expect such a long string and sometimes fails to show it correctly? I don't know, it's just my speculation. However, the last data block starting at offset 0x44 can be fixed manually, provided the rest of the file is correct. It should contain 64 ASCII-HEX digits, but it doesn't matter what data is there, because it's not used by the keygen for computations.

--- Code: ---$ rigup license your-keyfile.txt NSEH NSER NSEQ
rigup license - Version 0.1
H8LXHB8-QEXAC7W-ZJMN5KH-APD9CVM (NSEH = 0x1C087)
W2LAMX2-DBEFZCT-XSND62C-PG8JJVM (NSER = 0x1C08F)
5CAZKCC-2Z865FH-MQVBXUB-BDV8E8M (NSEQ = 0x1C097)
--- End code ---
NSEH = All options
NSER = All options + 100 MHz
NSEQ = All options + 200 MHz
License-code for 300 MHz is unknown. Thought it could be NSFH but there are reports that it doesn't work.
If you're brave you could play with rigup and license-codes. You could use hex codes, too:
--- Code: ---$ rigup license your-keyfile.txt 0x1C087 0x1C08F 0x1C097 0x1C0A7
rigup license - Version 0.1
H8LXHB8-QEXAC7W-ZJMN5KH-APD9CVM (NSEH = 0x1C087)
W2LAMX2-DBEFZCT-XSND62C-PG8JJVM (NSER = 0x1C08F)
5CAZKCC-2Z865FH-MQVBXUB-BDV8E8M (NSEQ = 0x1C097)
XYJ69WE-SBZABHL-69FYG4N-W6DH2VM (NSFH = 0x1C0A7)
--- End code ---
--- End quote ---
I didn't check it yet, but I think that 300 MHz + all options should be set by value of 0x1C0C7 (NS8H).

Hi,
1. Is the using DS2000 firmware on DS2000A reversable. Can you just replace it with original firmware later? Where do you get the original firmware. Is it possible backup the firmware?
2. Is this firmware altered or it's just the original non-A firmware?
3. Do you loose trial options? Is it possible after restoring original DS2000A firmware to still have the trial options?
4. I guess firmware updates is not an option when using the 00.02.01.00.03 from non-A series

I actually ended up using the rigol command manual before I got the answer in the thread, we use the manuals when we become desperate :D
