Hello,
I've a DSA815TG with boot 1.04, to get all licenses i had to solder write pin on Fram.
Does anybody have a way to get private key and generate License ?

* If the source is available that can help with trust issues (but nobody will take the time to compile it, and 80% of those that do will hassle you about where to get missing libraries)

For those, who are afraid of russian hackers, I've updated a zip-archive.  :-DD Now it consist of exe-file and sources. You are free to use or compile it.  ;)

Yeah. But No..

??????: 404

(Error: 404 - will the forum finally allow Cyrillic characters?)

Just an FYI of the bandwidth of the 'unlocked DS2072a - DS2302A' .

With well calibrated leveled sine wave gens, SG503 and SG504 (TEK) using my custom made remote head for flatness <0.1dB I re-evaluated the Rigol bandwidth.

Figures of merit:

150Mhz - Rigol is still accurate  matching the Vpp of the signal.

300Mhz - Rigol is down 2dB in amplitude.

400 Mhz - Rigol is down 3dB in amplitude.

I'd go with using it to 175Mhz max as reasonably accurate. Start factoring in losses past that.

This cross refernce check matches quite well with my VNA test results on the scope.

What's the problem with a flag and with a language?  :wtf:

Mind your Language a bit will you. Your posts with a funny URL look suspicious.
A lot of hackers come from Russia or from that region, so it is not so strange that people start asking questions. If then your language flag is set to German, your profile becomes even more strange.

This guy does not appear to be a "hacker" in a malicious context..  He is a physician from Ukraine who moved to Germany after "the revolution".  He was employed in Crimea at the time of the putsch,  when the newly formed Ukrainian government banned him from continuing work in the occupied territory.  From what I understand he is now a licensed MD in Germany.  I don't think his profile matches a 'script kiddie' who wants to crack your PC.   Just saying...
