Hantek - Tekway - DSO hack - get 200MHz bw for free

<< < (638/645) > >>

Tugo:
And what was procedure for your oscilloscope and what did you do to hack it to 200MHz?
I didn't hack it because I didn't know if it can be done with newer HW.
I believe we have the same HW and SW version.

And how did you test it to know that you really have 200MHz now?
Did you do just software hack or also HW?

Hi Tugo,

For the backup of the 8 elements, you need a key that contains in the root :
- dso5kp_backuptool2.up
- dumpbad.txt (empty file)
- oob.txt (empty file)
The saved files will be in the "dump" directory.
The operation takes a few minutes.

For the hack, I used the software "DSO-BW-Changer.exe" via the USB link (with the rear connector). Note that the oscilloscope does not restart itself as indicated, it must be rebooted.

I tested the hack with a VHF generator (which does not go higher than 160MHz), it works.

I just compared 2 backups (before and after the hack) with WinMerge, there are many differences between the 2 files "mtd5-rootfs.bin". The others are identical.


Tugo:
Did you do any HW mod like removing 2 SMD capacitors?

Bruno02:
No hardware modification, I didn't even open the case.

McJanDK77:
Is it possible to use this DSO BW Changer software for my DSO4104C ?
