Siglent SDS1000(X) / SDS2000(X) or LeCroy WaveAce (Blackfin) hacks?

Okay. If no telnet is possible, how to obtain the memdump? I found the SCDP C# program, which was posted in September 2018, but I don't know which SCPI commands are required for reading the memory.
Any hint where to start?
Thank you
Best regards

There are no SCPI commands to "read memory". If you need it, you'll have to craft your own command to do it.

Another possibility might be the JTAG access.

I see. Since I have no clue about SCPI programming, I will not further investigate.

But I managed to perform the BW hack. The mainboard of my scope has minor differences, but after removing the four caps, it seems that I can measure up to 300 MHz. I do not have a signal generator which is capable of providing such a high frequency. Hence I used my SSA 3021X TG and set the output to 0 dBm. For low frequencys the scope measures 1 Vpp. At 300 MHz configured at TG it still has a reliable reading of 300 MHz and 0.9 Vpp. I tried to increase the frequency, but it becomes unreliable beyond 320 MHz. At 400 MHz Nyquist comes in and the scope shows 332 MHz...

For those who are interested in photos, I attached some here.

Thanks to everybody who contributed to the BW hack and the modified FW.  :-+

Best regards

Hey guys, this thread starts with the options patch already done, anyone have a link to the thread discussing that?

Hello,

I have a SDS2204X. It will be nice to have more BW  8)
I download the last mod firmware from tv84, thanks a lot.
But on reply #10 there is a HW mod ( removing 4 caps ).

My scope is still under waranty so I didn't opened it wet.
I don't understand if all the SDS2000X series had those caps ?

Thank you for your help :)
