This.

I would much rather have bought a Agilent scope. But I went with the Rigol because I could enable the extra functions. If the hack didnt exsist, I would had saved up for a few more months for the Agilent. They win as far as customer support hands down.

Broke hobbyist like me, can't afford a Agilent $1.2k DSO with another $4k in options. But we can pull of $700~ after several months of saving.

Me too. I bought a scope and a spectrum analyzer precisely because there are option hacks. And then I bought a signal generator (without the hack option) because I like their products now.

The website with this generator is far to easy to use. Maybe Rigol can ignore some source code to compile somewhere in a ee-forum. But a website with a keygen generator for the masses? Seriously?

Tribute to cybernet and the other guys. You all do absolute awesome work!
cybernet:
some progress - there is another hidden key in the bootloader, that will launch arbitrary LDR files from USB sticks (without flashing anything ;-)
i've got now a partly working u-boot that can load from USB stick - and hence transfer a linux image via tftp .. booting that, is another topic, but its coming along ...

Same here I got sucked in on the first DS1052E Hack, now 4 RIGOL products later. ( See Pic )

Rigol, stop worrying about what we do with 'upgrading' your products, and start concentrating on customer support and software bugs.

To be frank, if they close these holes, i'll spend the very small margin extra for Agilent.

On the other side, I wonder what percentage of their customer base realizes these can be 'hacked'

Back on topic.....
Cybernet - Keep up the good work mate.

Wall-E:
Re. DP832 Power Supply

Does the 1.03c Keygen still work on the DP832?  I understand that 1. Firmware 01.06.00 should be installed,  2. Install the keys, and then 3. Upgrade the firmware to 01.08.00.
Does this still work Ok?   I seem to recall that someone said they lost everything including the metering accuracy.
Is there anything to this, and if so, can it be prevented?

Thank you for assistance, Wallie
