Does anyone have a link to download the DS/MSO1000Z firmware v00.04.03 ?

Are you sure that that Firmware is valid for the MSO series too? I was under the impression that the firmware differed between the MSO and DSO.

I installed that one on my MSO1104Z.

And how were the results? Hacks still there? Any noticable improvements?

Yes, it was hacked previously(trigger, decode, segmented memory, memory), and they are still there after flashing to 00.4.03.  I haven't noticed any differences, but I haven't used it extensively yet.

Recently purchased a DSA815-TG. UPS claims it will arrive tomorrow.
Just wondering if anyone has put any effort into enabling the options on the newer units with the updated bootloader. I'd really like to know if Rigol updated the public/private keys and/or did they change the option codes themselves.
I can probably do a jtag dump at some point if that is what is needed.

Also can anyone confirm if the hardware has been updated in the newer production units, I have read mention of a lower noise floor.


PS to Rigol - I bought the DSA815-TG because I am pleased with my DS1054Z that is now fully optioned out. If you remove the ability to enable features on all products people like myself will buy from another company. :)

Get ready to buy from another company. The only current hack for the DSA815 involves opening the device up and bridging the write protect pin on the FRAM chip to Vdd, pulling it high. This seems to persist the trial options indefinitely. No 10hz RBW though.

I am holding out on opening up my unit, hoping someone finds a soft-hack. I still have option time left and turn the DSA off when not on use. If I get low on option time, I will reconsider.

Considering I am willing to open it to JTAG it I have no problem shorting pins 7 and 8 of the FRAM for now - I'll verify it works first!
