Hydron:
OK so I wouldn't get too worked up about the NUMBER thing, the bandwidth seems to be an option only thing, unlike the old Tek scope BW hack.

When sending the LIST? command there isn't much of use in the output other than the actual keys used for activating each option (and the activation date) - could be useful if one lost the original info and cleared the list or something. These match the License keys on the document included in the original packaging (and the K36 bode plot key I was emailed).
STATUS doesn't seem to give any output, and no way I'm trying the rest.
Harjit:
@uski - curious how you figured out these commands?

Someone posted a txt file with all the commands earlier.
But otherwise... I am pretty sure you can run "strings" on the decrypted firmware image and get the same result (and possibly find other interesting stuff such as some error messages that can be interesting)

I didn't have time to play around with the firmware (yet?). Another option is to load it in IDA or a similar disassembler, and then things get even more interesting. :)

Some pretty cool content in the firmware...

An error message :


--- Code: ---1GHz Bandwidth extension is not supported
with present hardware configuration.
TXT_ID_LICENCE_OKL_1GHz_BW_UPGRADE_NOT_SUPPORTED
--- End code ---

And a bunch of license numbers and descriptions, including these :


--- Code: ---B1 - MSO 16 Logic Channels
TXT_ID_LICENCE_OKL_DESIG_B1
B200 - Bandwidth ext. 500MHz
TXT_ID_LICENCE_OKL_DESIG_B200
B201 - Bandwidth ext. 350MHz
TXT_ID_LICENCE_OKL_DESIG_B201
B202 - Bandwidth ext. 500MHz
TXT_ID_LICENCE_OKL_DESIG_B202
B203 - Bandwidth ext. 1GHz
TXT_ID_LICENCE_OKL_DESIG_B203
B204 - Bandwidth ext. 1GHz
TXT_ID_LICENCE_OKL_DESIG_B204
B205 - Bandwidth ext. 1GHz
TXT_ID_LICENCE_OKL_DESIG_B205
--- End code ---

Not saying it will work or it is supported... but these strings are there in the firmware  ^-^

Probably just some common stuff between the 2000, 3000 and 4000 series scopes.
