How does it compare to my OWON ?       



Thanks, F_E for sharing, about the pulser,
probably I missed some posts, what is the
final measurement you obtained from the
beast?

From the last post of the Jim Williams pulser thread

And the results are in! They range from 170pS to 210pS for a 8 vpp pulse measured at 20 to 80% into 50 ohm.

So the JW pulser is faster than Jim ever was able to measure. We are talking in the 30pS per volt range... Given that agilents calibrator does 15...

I'm wondering how they managed to pump 80GB/sec (assuming 8 bits per sample) through only 8 lanes. That would lead to 80Gbit/sec on each lane, effectively 80GHz?? Or do they employ PAM to get the Frequency down?
