Today I worked on my remote control GUI for the SDG2042X.

This project is now becoming usable for my test bench: Did some bugfixes, added configuration file, path settings (screenshot and pre-saved Settings) and, most important, context-sensitive input fields that depend on the waveform.

But the GUI still in a very early stage, at example, the ARB management isn't really working yet, that's still on my to-do list.

& yes, the GUI is ugly as hell, but at this stage of the project, the functionality is more important to me.

Improving my test bench for future projects, I wrote a small PyQt5 GUI to control my Siglent SDG2042X from a remote Ubuntu desktop.

It handles basic waveform setup, sweeps, bursts, presets (so you can adjust at the generator and than load down for later), ARB upload/download (not fully tested yet), and SCPI commands, also screenshots.

I’m more of a hardware guy than a coder (for sure there will be some bugs), so feedback are welcome. Fork if you like.

If I have any RF tech foo it is of the 1990s sort, so I end up accumulating stuff like this... an early version of the poor ham's scalar network analyzer (PHSNA) that I picked up because it includes a W7ZOI power meter board.

First task: figure out how it works before I apply power and what should happen when I do.

A literal DIY open bench
I am not sure if I'd buy it again, but it will serve its purpose

Would a 25Mhz oscilloscope be enough for testing on modern computers up to say the XPish era? #RetroComputing #TestBench

Yesterday we got the #VHDL #testbench for part of our #opensource #DVB-S2 #fpga amateur #satellite encoder working (and it PASSED!) on the command line, using GHDL. This is great! 🌈

The parallel effort in Xilinx Vivado didn't work, because vunit (a necessary component of the testbench) doesn't support xsim in Vivado.

This word salad boils down to "open source helps advanced digital communications in amateur radio"

The support for vunit working in Vivado has been a filed issue since 2017.
