This scope will measure rising edge to rising edge jitter with a noise floor of about 22 ps RMS. That's pretty cool for a scope that's sampling at 2 GHz, every 500 ps.
If I'd used channels 1 and 3, both would sample at 4 GHz. Gotta try that.

How do you know it's not an artifact?

Artifact? It's what the scope is reporting.
I have created known jitter to check the scope's algorithms. Seems right.

-- John Larkin Highland Technology, Inc Hey John, I got a couple of those scopes and the vertical trigger (+ or -) needs at least 2 CM of signal edge to lock. This seems excessively large and drives me metastable. The old Teks would lock on to a little wiggle. What say you? Cheers, Harry
