USB oscilloscopes

[no_one]

I am looking at USB interfaced PC O-scopes and was wondering if anyone has
experience with either PICO or Link in a 100MHz dual scope configuration.
I have access to plenty of equipment at work, so this is to fill my home
and/or hobby wish list.

Look very carefully at the specs if you decide to go with a pc-scope.
For 100 MHz on two channels you would probably want a 1 GHz real-time
sample on each channel. That gives you a 5th harmonic on a 100 MHz
signal that's just at Nyquist. AFAIK, there are no pc-scopes with that
capability (at least, not yet).

Some claim x GHz "equivalent" or "repetitive" sample rates but it's
likely that at least some of the important things you'll want to see
are not repetitive events.
