@ oz2cpu,
PM sent
oz2cpu:
thanks FransisM all done, packed and send..
To any one else. mail via this system dont seem to be working at the moment, nothing show up, and no notifications too,

Good Morning OZ2CPU,
yesterday the PCBs arrived! Looks very good! I'm impressed by your SMD soldering capabilities, I tried some 8050 yesterday and two jumped into Nirwana .... :palm:
I need much more practice.... |O
Unfortunately my 3D printer isn't working anymore. Last part I have finished was your SDS2000x+ blind plug, fits perfect!
After long investigations and part changing it seem to be the thermistor on the hot end. Now I'm awaiting a DuPont crimp tool from Aliexpress
for final repair. I keep you informed when I got the probes running, the tips are still on their way.
Thank you very much for this great piece of engineering! Keep you informed about my progress.

Haven't had time to do much with the LA since another project has taken over our available time, but hope to get back on this soon.
However, we can verify that Thomas (oz2cpu) LA Probe works well with standard 10 line ribbon cable (8 active, 2 ground), the twisted pair cable we have is a little too wide so used ribbon cable instead. Don't have a high speed pulse generator, but did verify that using a sine wave input from a AWG the Probe works to ~100MHz with ribbon. You do "see" a small amount of crosstalk, but that's expected, with twisted pair the crosstalk should be eliminated. Also can verify the 3D files print nicely.
Still waiting for a proper crimp tool and doublewide 16 connector "shells" for Dupont connector pins, so just used a single wide 8 "shell" and soldered the connector pins. As shown this supports the 8 active lines, and the ground lines are just a single Dupont connector.
Anyway, hat's off to Thomas (oz2cpu) for developing this DIY PA Probe for the Siglent Scope and making it available to others :clap: :-+
Best,
Mike

I acquired my 2104x+ three months ago and was surprised to discover that all the active parts for the LA were already inside the scope. Being a hobbyist and newly retired, I found it interesting as I never used myself such a piece of gear. Too expensive at the time.
I asked Thomas (oz2cpu) for the pcbs and all the parts he could provide.
In the mean time, I had to activate the needed option. I spent some time to dig into a thread about it and found all I had need for.
It was way more easy than expected and I ended up with a fully liberated scope !!!
I also built a test jig MCU based to have something to play with. I started with the PIC16F84 at it's beginning and now, mostly use PIC18F series wich satisfy my needs. Just a single pulse on each bit of two IO ports in a loop, to be sure I haven't mixed things up.
A smart guy made the soldering job of the tiny parts for me. I just had to solder the wires and close the boxes.
It worked like a charm at start.
The nice thing is I can see both digital and analog level of the same pulse.
I had some fun playing with the trigger and the options available.
Next step will be troubleshooting of a Z80 cpu board from the eighties. It fails to control water temperature in a coffee machine.
Thomas, without your offer wich was a bargain, the LA would have never been used on my scope. Some tens of MHz and half a meter length is all I have need for. It won't have an every day use so the official probe wasn't an option.
Thanks for all your effort, :-+
Francis
