Hi Robert,
I'm afraid I currently have no idea what your actual problem is and I don't see any apparent difference between the two screenshots, what is the problem that you see on the trace? Anyway, I thought I'd write you a line about LOGIC.

Yes, there's a limited amount of samples but surely you can have more than 1M AND higher samplig frequency. On a slow(ish) computer you might not be able to reach 24MHz but you should be able to go WAY up from where you are now. Just select, say 10M samples at 500kHz instead. Or does that not work for you for some reason?

You can give each channel a name in the software, just click on the text Channel 1, Channel 2 etc and punch in your name. That way you don't have to photoshop that in later.

I don't see you have any trigger set up, did you capture it "on the fly"?

/Henrik.
