worked like a charm!!!
Now it shows all official Version and only one line with 300m bandwidth

I cant belive it has the same hardware as the 2500 usd with 300mhz... and i paid only 788 USD and you guys from this thread made it happen !
Thanks!
So.. if we need warranty, all need to do is to uninstall the serial and update to stock firmware right ?
And probably those options will work even on future firmware updates ? since its a serial number ?( maybe isnt worthy updating..... the team is winning... why risk , right ?)

My question:

does your DS 2302A work stable as there it is mentioned in this forum not to be. So what is actually right?

I have a DS2072A, not 2302.... its hacked to 300 mhz..
Well... i have tested and not any problem what so ever until now.... And i believe it wont have any problem right ? its just a serial number freeing the functions, not any jailbreak on software really... you can even uninstall everything, update to stock firmware and use the serial that now you have, and it will give you all the options... so, probably just one serial wont give you any instability on the device right ?

As for the DS2072A being the same HW, please remember that no one with a DS2302A (to my knowledge) has posted test results on performance, so there is nothing to compare against just yet.

Hi there..
how can we test high frequencies close to 300 ? I dont have any generator.... do you know if i can probe on a computer mainbord something that would be close to those speeds ? like USB port in use, ram memory bus.. i dont know.... what the easiest way to test it at close to 300mhz ?
Thanks

Hi,

i tried to do the 300MZ option, but it failed.
I can only do the upgrade till DS2202A not DS2302A.
After sending the string: rigup ds2072a dump.txt there you receive after the NSFH:xxxxxxx-xxxxxxxx-xxxxxxx-xxxxxx
the question mark *=  untested,unconfirmed.

If i put the NFSH keys into the rigol2072a all options are installed but if stays by DS2072A.
What is wrong?

The NSFH option code turned out to be wrong (read a few pages back). Uninstall all options in your scope and then use NS8H code.

Thank you ,

simply question, how do i practice the NS8H ?
Where must i put it in?
