Yeah I'm just trying to get it working with what I have. I ordered a DreamSoucre DSLogic U3Pro32 Friday.

But hey I got it working, it really was that the PCI-E connector was a few tenths of a mm too thick, with the added solder/wires. The contact is still not great, not every time anyways.

Here a picture of some audio channel, and volume control data, that I'm bare-metal coding onto an ATtiny13A, to fix my stereo.

And here's a 3.3V 25MHz square wave from my SDG2142X, either triggered from CH2 or D7, which is the farthest from the data probe GND pin.

And my CH2 scope probe has the big long GND lead, and I'm just clipped on a few cm away from the series 360R resistor I probed, before it enters the scope. So the signal's probably a bit better than it looks.

DIY Logic Analyzer Probe with SDS2204X HD
« Reply #251 on: January 21, 2025, 07:47:15 pm »
I'm about to purchase a SDS2204X HD. Will this DIY probe work with it, or is the software locked? I probably only need low frequency use, so the DIY probe could make sense for now, could buy the SPL2016 later if I need more bandwidth/precision.

MSO licensing for all DSO's that support it has been abolished in recent firmware.

This allows one MSO probe to be used on any scope that supports it.
