do, is to use a VBW
John,
You are correct in noting that the current proposal for limits above 1 GHz
in CISPR 22 uses a peak detector, rather than the average detector called
out in the FCC Rules. This has been a major issue in the US CISPR G TAG.
While we have gotten other items fixed, we have been unable to get

John,
Characteristics of average measuring receivers for
measuring disturbance levels in the range from
9 kHz to 1 GHz are given in CISPR Publication 16-1.
Limits for radiated disturbances above 1 GHz
are peak detector levels, the only detector to be
used for determining compliance above 1
John,
MY HP 8591EM will in fact perform average measurements. The manual makes
specific reference to CISPR 11 and CISPR 16 for compliances. The analyzer
is rated to 1.8 GHz. The HP 8593 series goes even higher.
