Thank you CF for your info ...and patience.
As of this post I still haven't got the key gen to work .  :(
I have as attached a
TDS5104 Serial B020296
VM5000(TDS5104B) Serial B022889
Which i would love to fully enable.
Maybe if you get the time you could work your magic on keys for both .
I have no problems fixing these scopes but the python gen eludes me .

Hi nicnac117,

No problem to create Option Keys.

For the TDS5104 it is:

PZPXQ-QZM9F-7KVUD-VFK8A-SRVWR-LNTE

And for the TDS5104B it should be:

P9F7Z-895MU-6J3E3-MKKR2-SRUXR-JQTA

Option Mask: 0444+14 F's.

But when I use validate.py to split out the Option Mask of this particular VM5000/TDS5104B I got the following Mask: 04 00 00 00 00 00 00 04 00 00 00 00 00 00 00 03 00 00. In this case 14 F's seems too little (the 3 on the 28 th position).

Thus with the maximum number of F's (32) it is:

XTZKV-J8CV2-QLNBU-GTG2R-F2MJZ-H2QF2-5JZH2-QF25J-ZH2A
 
Enjoy,

much appreciated, Thank you
Is the option data stored in an eeprom on the acquisition board? Just wonderoing as its not on the hard drive as reloading everything doesnt wipe the installed options .

Hi nicnac117,

I assume the generated TDS5104B Option Key enables all options (including the VM5000 HD and SD Video Option). Nevertheless I noticed a CRC Mismatch when using validate.py on this newly generated Option Key. With 28 F's'and 30 F's there is no CRC Mismatch.

Option Key based on 28 F's:

F3ZPV-28UDS-Q6LLY-CDLWK-PDR6B-MWAPD-96BMW-APD96

Option Key based on 30 F's:

P3H7V-29VDU-N2WS3-VFK9A-SRVWR-LNTWM-C7HJ8-BSRDW-RC

I assume both will also work with shorter lists of App available, but not installed (I have no TDS5104B on hand).
