Attached my notes about the mystery file.
Attached the full list of SCPI commands extracted from the 00.01.06.00.01 firmware image.

Chicken, thanks for the files. I've also done a preliminary look and have a FW parser.
I'll try to check your conclusions with my notes of Rigol FW.
SCPI command list has been here for sometime. Did you crosscheck?
chicken:
I wasn't aware of that thread. The only difference is :SYSTem:PRESet (620, 0x4016cdd8, :SYSTem:PRESet, Programming Guide) which is missing in your list.

So no easy hack, if possible at all...

Does anyone have pictures of the IQ board?
Another, simpler DIY project would be a 10 MHz OCXO. The edge connector looks easy enough to interface with and I didn't see anything that indicates a license key to enable this option. Again, anyone got pictures of the official OXCO?
TurboTom:
A DIY internal OCXO would surely be a nice project but since the DSG has got an input for an external reference supply, the same or better performance can be achieved by just hooking up an external GPSDO which is inexpensively available or an atomic reference oscillator (also once in a while available at a bargain second hand).
