DG4000 - a firmware investigation
tkarlmann:
I'm new to all this, and I'm seeing 14 pages of notes to this thread. I also noted that the early recommendation of the Amontec JTAGkey seems to be no longer possible, as the company is no longer in business.
https://startingelectronics.org/articles/embedded-tools/amontec-info/ See link at left.
I'm starting virtually from scratch, and will need all the assistance I can get, although I've been an EE for 30+ years. I now have a DS1052E, which also needs to be modded, and I am planning on outfitting a home lab. Is such a procedure available? Thanks. I would like to start with the DG4062, and upgrade it when possible. For now, I'd like to do these mods. Can I make it look like the DG4202? Can I calibrate it to the limits of the DG4202?
Also, I will be buying new equipment with whatever firmware is current. I will get: DS1054Z, DS2072A, DG4062, DM3068, and DP832, with a strong look at Rigol's new DL3031A.
All help Appreciated!

I bought rigol DG4062 with the serial number DG4Exxxxxxxxx. The software version is 00.01.12 with that new boot loader. I want to hack my signal generator to DG4162. Is it possible to hack?
I read the previous messages from the forum. May I downgrade the firmware version to 00.01.07 or below, then to change the model number to DG4162? After that, the re-calibration is performed before I upgrade it to the lastest firmware. Are these correct procedures to hack DG4062? I do not fully understand how to perform the downgrading procedures(including boot loader) . Could anyone give me advice?

Trying to run the online compile on post #104 but first I had to fill in Project>Compile Options (and run options) and. after compiling, there's no file to download. Can anyone help?

Apparently, there's new firmware available for the DG4000 series on http://www.rigol.com/File/ProductSoftWare/20180509/DG4000(DSP)update.rar (01.14.00.01 vs. 01.12.00.02). Has anybody been successful installing this file on his DG4000? I didn't succees as yet, and I don't really believe that all of my thumb drives are incopatible (tested about five of my older ones that run well with an operating DG4000 as a storage device. Just for information, my DG4102 hasn't been tampered with (too new model, the patch isn't working... :( ).
Cheers,
Thomas

Thanks Peter,
I finally managed to dig out a really ancient 512MB thumb drive, and -- surprise, surprise -- with that I was finally able to update the firmware. I tested with many different thumb drives from 4 to 32GB that all were detected and usable during normal operation of the generator, but they all failed at updating the firmware.
Unfortunately, it appears that none of the bugs / annoyances that bugger me most with this generator had been addressed. In pulse mode, the nasty 4µs runt pulse of half selected amplitude is still there when changing the pulse width. The encoder response (even/constant/predictable number of increments per detent) hasn't been improved at all. And Rigol didn't bother to have a go at the menu structure to select built-in arbitrary waveforms.
So my recommendation to all those out there shopping for a middle-range AWG, don't even spend a thought on this one, it's still crap and probably wouldn't receive any substantial improvements anymore. I'ld be happy to be proven wrong, though.
Cheers,
Thomas
