I will try this week. It's seem to be a good work :)

What options are there to explicitly save the existing calibration file
(the still unchanged original factory calibration) of an SDM3055 ?

Hi,

Since the start of the health crisis in France and around the world, I have put this project on standby.
I currently have to manage 7/7 server clusters (from several websites) so that children can work during confinement.
I will resume the development of this project at the end of confinement or when I have free time again.

Take care of yourself and your loved ones.


Alexia from France.

Nice Work alexvg!  Hope all goes well and that we see you back on this project.

tautech, maybe you could encourage Siglent to hire alexvg or retain alexvg's services.  Sure looks like a lot of creative and capable product management and product development horsepower that could benefit Siglent, their products, and their customers.

"Me Too":  Yes, great work alexvg!  I hope things calm down in the world soon so we can all get back to kewl projects like this one.

7.5 digits : https://www.eevblog.com/forum/testgear/hacking-the-siglent-sdm3055/msg2612406/#msg2612406

I have an SDM3065X-SC and want to try out UI and 7.5 digit FW mods if/when it's possible to do so.  I considered attempting the 7.5 digit hack per the instructions, but since I have a different model, I thought I'd ask first to avoid messing things up.  Is it reasonably "safe" to try out the 7.5 digit mod on a 3065?

I have an sdm3045x and am pretty satisfied with it for the most part but, the resistance measurement 2 and 4 wire only measure to 3 digits beyond the decimal in its lowest 600 range, how hard would it be to hack a fourth digit? I'd be willing to upgrade my voltage reference to the max one used in the 3055 if need be!

Some news :
I'm working on an interface using a HTML/CSS rendering for a more scalable and flexible possibilities/features.
It takes a very long time because the power of the main CPU is very limited: I need to do a high level of optimizations and remove some CSS features (who need too much process time/power).
Why put a full HTML/CSS rendering engine on an embedded device. That's really inefficient. I don't like when people do it on Desktop, but it's just awful on embedded.
You can always use SDL or QT embedded to do the GUI.

I've done my own fair share of aftermarket firmware and SDL usually works quite well.

It's a different main board, i wouldnt normally say this but you got the top of the line model, i'd leave it be since its the flagship less you are out of warranty or the like

You can cross application files across same mainboard revisions safely, beyond that you are on your own, its the reason you can turn the new SSA 3000X Plus into a 3.2Ghz SVA model, same main board, just a different application file

True on the hardware.  Beyond that it depends on how they architected the firmware/software if the UI code is well separated from the underneath bits.  Most of the firmware hacks I've seen posted are reasonably safe and reversible to try but only for a very specific model.  After I posted I finally saw a note from OP of the "thou shalt not" try on other models...   :palm:  Was hoping it might be possible to safely kill normal UI process and try out OP's much better UI.  Odds of that actually working are low, but thought I'd ask.  I'm not up to speed enough to hack around with it myself yet, need to get through a few more learning curves with JTAG and the like.

(*Sarcastic*) And thanks a lot for bringing up the SSA3000X+ "upgrade".  It took months to convince myself to wait until next year before digging into the RF side of things and getting related "field upgradable" SA/VNA toys...  -ER-, I mean essential tools.   >:D
...  SVA?  Sounds like I'm behind on reading.  But I really, really shouldn't catch up.  Bad idea.  Bad, bad idea.  I don't go to TEA meetings.  I don't have a problem.

Hello,
Just a little message to thank you for your support.
I have been sick with Covid-19 since June. Despite all the precautions taken (mask, distance, hand washing ...), that was not enough.
It's very difficult everyday with a lot of symptoms. The healthcare team is great but clueless.
Please protect each other, take care of yourself.

I want to thank you for this awesome work. 3055 is very capable device. Running 6-1/2 digit mod, I checked 4 wire resistance against 10OOhm 0,002% resistance standard. Only last digit was noisy same as my freshly calibrated Keithley 2100.  Also I compensated wire resistance because it was a little 0,0136 Ohm off when 4 wires shorted. After connecting to reference resistor the reading was stable up to last digit. All measurements were dine after 2 hours warm up.

Anyone has news of Alexia ? I just found this thread and the last message is months old, so I am worried now !
