Nice work!
I do have a defective non-locking FE-5680A, but the problems it has
(incorrect serial command replies, way off DDS tuning values, and
absence of 10 MHz once the microcontroller boots up) makes me think
there's a problem with the CPLD or even the firmware in flash. I
don't think it would be a good candidate for a firmware dump.
