I downloaded your zip file with the various backup and upgrade scripts - loaded afg_HDG2002B_to_HDG2102C.upk on a FAT32 formatted USB and....

...nothing.  |O

I get an error -129 when I try to perform the update (or -4 if I retry).

newb error on my part obviously... But advice appreciated...

I suppose that the script can't find system.inf... What firmware version do you have?
This script should work on a HDB2002B with firmware >= 1.00.2 where system.inf is located in /dso/root. It won't work with firmware 1.00.1 where system.inf is in /etc.
I am not at home at the moment so I can't check further  :-//

I haven't been following this thread at all, and just read the initial posting.
Here are my questions to make a long story short, and jump in the subject area :)

Is the latest HW version of HDG2000B (5MHz) still hackable to HDG2102B (100MHz)?

Where can I buy HDG2000B in Europe? Which distributor?
How much does HDG2000B and HDG2102B cost respectively? What is the price difference?

How does the HDG2000 series perform?
Let's say I want to use it in the 25MHz region. Does it perform as good as the Rigol SDG1025 in the 25MHz range?
Let's say I want to use it in the 100MHz region. Does it perform as good as the Rigol DG4102 in the 100MHz range?

Is there a formal document with all the details for performing the hack? I don't like to scroll through 35 pages of postings :) I am looking for a summary that comprises the details on how to do the "upgrade", what the pros are, what the cons are, which risks there are, impact of future FW upgrades on performed "upgrade", etc.

Your help will be highly appreciated. I jumped straight from the initial entry to the last entry, and want to get up to speed on this "upgrade" :)

The last known version is 1.00.3. It is still hackable.

I got mine there: http://www.rigoloscilloscope.fr/wholesale/Hantek-HDG2002B-2-Channels-16Bits-250MSa-s-Function-Arbitrary-Waveform-Generator-5MHz-695.html
They also have Websites for Uk, Germany... but it comes from china.

Good hardware potential but low software quality. Hopefully a opensource version will be available in the next weeks/months.
alex.forencich worked on the FPGA software and I am currently working on a GUI version.
I don't have other AWG to compare with.

Hack is just done by changing the name of the device in a file.
You can also do it using the "upgrade" functionnality of the HDG with a.upk file. You can download it on my onedrive:
https://onedrive.live.com/?id=C666E0DC0AF0C9E2!124&cid=C666E0DC0AF0C9E2&group=0&authkey=!AMtRrjm2d33uI8QThere is a readme.
pros: 100Mhz limit
cons: you have to perform a complete calibration (I wrote a tool working in Excel to automate the process, available in the previous posts)
no known risk as long as you perform a full backup of your device (scripts on onedrive too).

I can't (yet!) directly compare it to an SDG1025.

I can however compare it to the dual 25MHz signal generators integrated into the DS/MSO1000Z-S scopes, because despite the inevitably more fiddly interface on the scopes, the Rigol is far better just from a software reliability aspect.

This AWG had the prospects of being a really useful piece of test gear, but regretfully out of the box it's little more than a toy I'm afraid. This is almost all down to the quality of the software being really very bad. There isn't much redeeming to say about it other than the hardware itself, which isn't too bad.

The proof is in the pudding, and regrettably this unit doesn't get used that much as the software just is not trustworthy enough: I have to double check what it's outputting before applying it to a DUT for fear it might do some damage!

If you're a tinkerer, with time on your hands, you might just about suffer its limitations, but a serious piece of TE it's not I'm afraid. Looks like it's the result of the software dept going out for a boozy lunch and never coming back.
