Kaan,

I developed and proposed flow chart - Decision tree for peak detector
measurements, at least six years ago at U.S. National Committee for IEC
TAG for CISPR SC G. I presented the same document later that year in
Berlin to CISPR SC A and SC G on behalf of U.S. National Committees.
Proposal has been approved with minor modifications suggested by Israel
and Japan National Committees. It is published as CISPR Publication
22:1997 Annex B (normative), page 85 and will be propagated as
applicable throughout other CISPR publications.

Intention of that document was to formalize rather common practice to
use peak instead of quasi peak or average detector for conducted
disturbance measurements at 150 kHz to 30 MHz. Use of peak detector
speed up the measurement process. If product fail the test by using peak
detector, there would be still a chance to pass the test by using
prescribed QP or AVG detectors.

Document allows use of peak detector instead of QP and AVG and QP
instead of AVG. It does not mandate it. In a case of dispute, precedence
results are with prescribed QP and AVG detectors. Document did not
affect limits.
