The short answer is - quasi-peak. The long answer is contained in 15.35(a) below.
Ghery S. Pettit Intel Corporation ยง15.35 Measurement detector functions and bandwidths. - The conducted and radiated emission limits shown in this part are based on the following, unless otherwise specified elsewhere in this part: (a) On any frequency or frequencies below or equal to 1000 MHz, the limits shown are based on measuring equipment employing a CISPR quasi-peak detector function and related measurement bandwidths, unless otherwise specified. The specifications for the measuring instrument using the CISPR quasi-peak detector can be found in Publication 16 of the International Special Committee on Radio Interference (CISPR) of the International Electrotechnical Commission. As an alternative to CISPR quasi-peak measurements, the responsible party, at its option, may demonstrate compliance with the emission limits using measuring equipment employing a peak detector function, properly adjusted for such factors as pulse desensitization, as long as the same bandwidths as indicated for CISPR quasi-peak measurements are employed.

Bagdons Sent: Wednesday, August 24, 2005 8:04 AM To: [email protected] Subject: EMC Question re post Can anyone comment on the FCC Part 15.107 Clause (c). The limit is stated at 1000 uV. Is this measured in Peak, Quasi Peak or Average and is there both an Quasi Peak and an Average limit necessary? Thank you Duane -- Duane R.
