Hacking the Siglent SDM3055 Bench DMM

Hi,
I'm just copy-paste last news from my blog :

I've received stuffs to build the compute server needed to analyse all captured data from Siglent SDM3055 A/D converter (AD7190).
I'm also working on network/hosting/servers/emails due to massive increasing of internet attacks.
All these tasks take me long time.

About the new software for the Siglent SDM3055, the resampling implementation (power line sync) is not fully operationnal. But the first tests were very good (around 2 bits improvement over noise free bits).

It's nice to see this project back on track.

As you have root access to the OS and are re-writing the GUI, a really useful feature would be a custom maths option, and the ability to display results in user definable units.

Use case: measuring the mV from a current shunt. Rarely do you see 1mV per A unless you carefully select the shunt design (just read the mV range in A otherwise). For a shunt that outputs 2.25mv/A (say) you could program the meter to divide the mV range by 2.25 and output to the display in A. Saves having to do the mental arithmetic.

We already have this ability for any meter with SCPI and a computer, but there's no reason it couldn't be done on the meter itself. Rigol have this facility on the 2000 series Oscopes, and R&S on their 1000 series Oscopes (and up), but it's hit and miss as to whether it's implemented or not. I guess manufacturers don't want us programming our own options that could be sold.

I ordered a 3055 yesterday........are there any hw revisions over the years that could cause incompatibility?

Initially reading through this page I was skeptical when I saw the poll asking if people would pay for a firmware.  Even responded "no" to the poll  :-DD. But after seeing the youtube videos of what this thing looks like - Yea. Absolutely. On two conditions though....if you release the appropriate linux sources (keep your app layer closed), and if you provide a tool to backup/restore the original calibrations......not sure what the limitations are here, i know you couldnt provide the file but maybe even a tool that accepts an original firmware file to "go back".....Because if im paying for something - I'd be willing to pay a little bit more for it to be the complete package with the things I listed.....

Otherwise open a github and let us join in :D

Hi.
I had a few weeks of break shared between my family and my job.
I've wanted to take this break to provide a better work now.

I've read all your private messages or commentaries.
I'll hope to provide you some answer in a near future.


Bye.

Alexia from France.
