The Siglent SDG2042X Thread

Another little play with harmonics and phasing with a 2ch AWG is in this old thread:

Gday,

is anyone interested in a web UI for the SDG2000x ?
Here's my work in progress...


All the buttons work, screen refresh is automatic.

Looking good!

Looks very nice.  Are you planning to sell it or make it available for free?  Source code or executable available?

My 2042X  exhibits the same behaviour as RoV's.

Thanks!

Probably free but with a high level of guilt to encourage donations

I should have a build available in a few days.

its basically feature complete with a couple more buttons to implement on the frequency counter view and a smattering of layout issues to kill. I much prefer burning my fingers on a hakko than fighting html, css, js!

It's a handful of files that need to live on a webserver BUT right now it also needs to support a cgi-bin perl script to act as the proxy/gateway cos browsers can't make naked TCP connections.
One upside of this is that the proxy/gateway component could just as easily use serial rather than TCP/IP for the devices that dont do ethernet

Another preview (/tease)

Same HW/SW, same settings, same behaviour.

That was with the SDS1104X-E, but I still have my SDS2504X HD...

I used him to resolve this further.
Interesting:
The sweep ends as expected at 10Mhz - But then there is nothing at first, the first frequency is not the start frequency of 1kHz as expected, but something around 10.8kHz and then with the increased level.
This continues until about 290kHz, then the level drops and remains constant until the sweep ends at 10Mhz.
If you increase the start frequency to 10kHz, there is no longer a "pause", but the increased level remains the same for the time being.

That looks great, I'd love to get a hold of this Would definitely be nicer to use than my macros for SCPI commands in a text terminal.

Then you'll hopefully like my latest work
- scpi command history (cursor up/down), t
- macros can use C?: instead of C1 or C2 and you can use a dropdown to set the channel it gets replaced with
- able view where i split on commas
- both the plaintext and table areas are scrollable
- the height of the scpi are is configurable so if you want standalone use, go nuts and use more screen realestate.



I'm super happy so far with the front end - the backend is a horrible cgi-bin perl script (for now).

got a linux box with a webserver and perl handy?
I've just been using a pi4 but a pi0 or a crappy old laptop would do fine too.

Yep Got a small Optiplex Micro sitting on my desk that is my VM machine.

Finally got it up on github https://github.com/penfold42/SDGRemote/

Documentation very much a work in progress, but would love your early feedback and questions.

If github's actions complete, there should be a "live" demo instance running at
https://penfold42.github.io/SDGRemote/

[penfold42]

Updated version posted today.
- Now uses a python websockets listener that leverages PyVISA to talk to the device.
- It also serves up the html content so you dont need a separate web server
- Much improved README.md and INSTALL.md
- Added [Copy] buttons to the SCPI results

"Live" demo here https://penfold42.github.io/SDGRemote/

Would love to get any and all feedback here or on github.

I've been using the websockets version for a few hours now and it works great. Thanks for this so much!

Just now on my SDG2042X when it turned on I see

DAC:           failed(chip id)
EEPROM:     failed()
FPGA:         failed()

Please press any function key to exit!

Anybody seen this before?

Then does it boot as it should ?

It does, but there is no signal on any of the outputs.
Otherwise everything looks ok and normal.

Thanks, will check what I have in it shortly. I think I was updating it recently....

Yes, that is what I have in there. Have the latest firmware.

[St66666]

All the voltages according to page 68 of the service manual are there, including the 10MHz signal.

FPGA LED is flashing HL1 is flashing. HL2 is on.
HL1 LED beside the flash chip U4 on the other board is flashing in a pattern.

I have a suspicion that it might be the DAC what failed.

[tautech]

Yes, that is what I have in there. Have the latest firmware.

Okay message me via PM with your email address and we'll run a recovery package.

Do you think it will make a difference?
It boots up to a "normal" looking state, so the software should not be an issue. It just has no signal on the output BNCs.
This is going to be a hardware problem
