So please tell me, if I order the 100 MHz DSO, will it be possible to unlock it to 300 MHz?

No, the A versions has not been hacked yet.

Makes me wonder if "ch" relates to the number of scope channels.

--- Quote ---The LA on MSO4000 looks to be plugged into a connector (not mounted in DS4000) next to the lone (display handling?) FPGA near the Blackfin.
There is a cut out in the PCB with mechanical supports for the probe connector on the front.
Presumably there is a LA board in between with some FPGA on it.

It seems to be the same design strategy to the older DS1002E/DS1002D models line, which share the same exactly PCB that has headers to carry the 'optional' logic analyzer add-on board the D models include. There are two slightly different firmware update versions though, one for the E model and one for the D one, since there are no HW revision selection switches (the populated/unpopulated resistors network) on board.

but according to recent finds, one should think that is matter of minutes if just someone do an jtag dump of an A serie..
I'm definately going for the A(with s), but 100 or 200... that's the question..

Carrington:
Cybernet has done it, again! *ole*  :-+

Now I'm very busy and I can't test anything (check the BW for example).

Anyway. How is the new table?


--- Quote ---Code table: Use DSAx for a official key, and use VSAx for a trial key.

x  200, 100, Mem, Dec, Trig

A   none
B   ==   ==   ==   ==   on
C   ==   ==   ==   on   ==
D   ==   ==   ==   on   on
E   ==   ==   on   ==   ==
F   ==   ==   on   ==   on
G   ==   ==   on   on   ==
H   ==   ==   on   on   on

Note: keys A..H wont change the model, only ADD an option.

2102:

J   ==   on   ==   ==   ==   
K   ==   on   ==   ==   on
L   ==   on   ==   on   ==
M   ==   on   ==   on   on
N   ==   on   on   ==   ==
P   ==   on   on   ==   on
Q   ==   on   on   on   ==
R   ==   on   on   on   on   <-  All 2102

2202:

S   on   ==   ==   ==   ==   
T   on   ==   ==   ==   on
U   on   ==   ==   on   ==
V   on   ==   ==   on   on
W   on   ==   on   ==   ==
X   on   ==   on   ==   on
Y   on   ==   on   on   ==
Z   on   ==   on   on   on   <-  All 2202

DONT USE BELOW Not recommended, as activates 2102 and also 2202:

2   on   on   ==   ==   ==
3   on   on   ==   ==   on
4   on   on   ==   on   ==
5   on   on   ==   on   on
6   on   on   on   ==   ==
7   on   on   on   ==   on
8   on   on   on   on   ==
9   on   on   on   on   on

I guess I'm not following everything here, has a key been generated that works on an A model yet?

Also, does anyone know HOW the keyboard connects to the blackfin, what pins/registers/interface?
