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
