I seem to remember the caps were specified in an earlier version of the
standard, and are no longer required (issue 2, rev 1 February 1999). My
understanding is that the LISN is that used for CISPR measurements.

Subject: Bellcore GP-1089 emissions testing: LISN
test setup
I'm looking through Bellcore GR-1089 Issue 2 Revision 1 for
details on the test
setup for conducted emissions testing.
I was under the impression that some of the measurements
involved use of large
RF bypass caps to ground, and the interference currents
through the capacitor
were measured.
While I found spec limits and test setups for current
probe-style measurements,
all the figures simply display a power input network marked
'LISN', which I
assume to be the standard 50 ohm network. I can't find a
reference that
explicitly discusses the use of an RF bypass cap.
Could someone point me to the appropriate section?
