(I believe) I've generated the code for EJ using the Python script, but there is no option to install it (1.3.9R6)
Because there is no eyediagram/jitter analyzis option for the 2000XP in real, this isn´t a hidden easteregg feature..
EJ - SDS-5000X-EJ - SDS_2000XP_EJ - SDS6000Pro-EJ
I think, it´s only "there" because all the three scopetypes are using more or less the same software.
A few months before, we got the same problem on a lecroy if I remember it right.
Installing all "theoretical possible" licenses but won´t work correctly.
I think it was on a WS3000 scope.
