Hello,
First of all let me thank for supplying the options unlocking site/software. I successfully unlocked may new oscilloscope (DS1054z) with this unlocking key generator. It is a great addon and a magnificant help working with the oscilloscope.
Now I bought at ebay a used DSA 815 spectrum analyzer. Of course before I bought it I verified, if I could unlock this aswell. Firmware is: 1.07.
Everything went fine until I reached the point where I need to enter the "-" sign in the code. It seems not to be possible to enter this. Without the "-" it does not work.
Is it no longer possible to unlock the DSA 815?
If so may I kindly ask the programmers to look on the code if it is possible to modify it to the new firmware?
Would it help to downgrade the firmware, enter the codes and upgrade to the newest? If so is there an FTP site where I can download the FW?
Does anybody know what happens if I update an unlocked device with new firmware?
Thank you very much in advance
Alex
