Just a quick note, for anyone with a 2000 series scope. I notice that in the 2.0 update, the license keys which existed for serial-decode options, are no longer present.
So far as I know, those keys could not be activated, though perhaps it could be done by some additional trick. However on cursory inspection, it seems that all references to this capability have been removed from the 2k scopes, perhaps also including any dormant code to make the features work (though presumably the bulk is still in there, as it is shared with the 3k).
I'm guessing Agilent are in no hurry to add this to the low end models.
I've not upgraded my scope just yet...
