Maybe I am blind but I don't see any candidates for a Lattice PLD (except maybe the small clock generation device next to the ADC and sample FPGA).
When in the teardown was this? and was he talking about the DS2k?

keyboard/leds on the frontpanel

Duh... That makes sense yes.
Not so interested in that I guess, must have been absent minded watching that part.

Carrington:
Is this correct?
IMHO would be interesting know the entire table, and thus activate the desired options with a single key.


--- Code: ---Code table: Use DSYX for a official key, and use VSYX for a trial key.

I have not found what * dose yet.
The "*" unknown option dose not turn on 50ohm for my DS2072 HW 2. 
-------------------------------------------------------------------------------------
Also tried DSI9 through DSZ9. Got license unavailability.  I'm guessing its not a good idea to use DS*9 option same as before.

New firmware is out for DS1000Z, version 00.02.01.SP1

It has quite a lot of bug fixes and seems to have faster GUI as well.  :-+

Now its possible to export the full memory of points as wfm files, but I have not found any software that supports these files, either to open or convert them... Does Rigol have any software for this?
