[TowerTalk] 4 port network analyzers for balun measurements

You should fixture the balun under test on a ground plane with
4 connectors grounded to that plane.  The 4 analyzer cables go
to these connectors.  You don't connect anything from the DUT
to the ground plane.  Alternately, you can do a 3 port measurement
in which case the unbalanced port goes directly to the analyzer.
Again, the Agilent software walks you through the setup possibilities.

>>>Placing an "open" wound 2.4" toroid BALUN on/near a ground plane will
affect the real performance of that BALUN which is not the case with common
"enclosed" binocular BALUNS used in industry.

 Just my $0.02
