Network analyzers

[Daniel Eischen]

So what are all the cool folks now using for network
analyzers.  We'd like to be able to capture and analyze
from all the common media: 10Base2/BNC, 10BaseT/UTP,
100BaseTX, 100BaseFX, 1000BaseTX (copper, SX, LX).
Cost is not much of a concern (your U.S. tax dollars
hard at work!) as capabilities and features.

I was pointed at the Agilent J6800A series by someone
here at work:

Any other recommendations?

Thanks,
