However in C63.4 : 2000, Section 5.4.6.5 (NSA for alternative test sites) a
groundplane is called out. Section 5.4.6.5 is referenced from Section
5.4.2. The very last sentence of Section 5.4.6.5 states, "The alternative
test site is considered suitable for performing radiated emissions testing
if all NSA measurements prescribed above meet the requirements of 5.4.6.1
and the reference groundplane requirements of 5.4.3...."

Please respond to "KC
CHAN [PDD]"
Just want to share with you all what I found.
For alternative test sites of radiated emission testing,
C63.4 : 2001
In Section 5.4.2, it only requires volumetric NSA requirements, no
requirement for ground plane.
C63.4 : 1992
In section 5.4.2, it requires volumetric NSA requirements(5.4.6) and ground
plane requirements( 5.4.3)
CISPR 16-1 : 1998
In section 16.7.3, it requires both volumetric NSA and ground plane
requirements.
Any charge of the latest CISPR 16-1: 1999 ?
