Grace,
CISPR 16-1 defines LISNs of 50Ohms||50µH + 5Ohms, 50Ohms||50µH and
50Ohms||5µH +1Ohm.
The 150Ohms V-network and the 150Ohms delta-network are also covered.
CISPR 22 refers in section 9.3 to CISPR 16-1 for LISNs to be used for testing.

I don't have a copy of CISPR 16 to reference and so I am curious about how one
calibrates an AMN? (or an antenna for that matter). I can see characterizing
the AMN so that its transducer factor versus frequency is known and can be then
used to calculate a uV

So I would have to deduce then that ANSI C63.4 is schizophrenic, in that
it doesn't trust the specified LISNs to work as they say they should. If
