With this version is available the 300MHz BW Option, but i have read that 200MHz BW option give more performance in LF than 300MHz in HW 1. Is the same for HW 2 or i can Install 300MHz BW with no problem in my HW 2?

For HW 2 use 300 MHz.

I search for: 200MHz + All Option (include CAN), 300MHz + All Option.

Use DSHH for HW 2 (300 MHz with all options).

Gentlemen,
I recently purchased a DS2072A from Tequipment and discovered this thread in regards to hacking it (nice work so far!) I've opened it up and I'm trying to get another dump as it seems like that would be useful to people. I would have offered to write those C routines but I guess someone beat me to it. I have two different JTAG interfaces on hand, a Xilinx Platform USB Cable, and an Altera USB Blaster. I first tried the Xilinx cable under Linux with bfin-jtag with no luck even connecting to it, same with the Altera one. I decided to give it a try under windows and first tried to generic urjtag package, which works with the Altera cable and I see the BF526 (see image). Unfortunately bfin-jtag doesn't want to see either interface... (Both cables work fine with their respective proprietary software.)
It looks like the generic urjtag doesn't have the bus support needed, is this correct? I see many more options from "help initbus" under bfin-jtag.
I've tried installing different versions of the drivers etc, with no luck, but it looks like maybe bfin-jtag is looking for a different USB VID/PID based on the message. Anyone have any ideas? I don't mind ordering yet-another JTAG cable, but I assume the sooner I can post another memory dump the better.
My scope came with software 00.02.00 and I haven't updated it.

But it's the old problem: People are only sitting around and waiting for the keygen and don't would like to break her warranty seal on the scope to provide a memory dump... This is bad indeed... ::)

Today I ordered a DS2072A and a Segger J-Link JTAG adapter. I hope I can provide a memory dump next week .

Hi,
Today I received my DS2072A, I had ordered a DS2072 non A from Batronix (Germany) but received a A model. I think non-A model are going to be replaced by A.
I'm really insterested by the possibility to unlock decoding options.
Reading this topic I understood that you need memory dump from A model to help decrypt the protection.
I would like to help and I'm ready to open my oscilloscope to make this dump but I'm not very familiar with JTAG, maybe someone could make a small tutorial to explain how to proceed ?
For now I have only a Bus Pirate that can act as a slow JTAG device, but if needed I could buy a real JTAG programmer.
