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..

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?
