If memory serves me this is buried in 15.35(b) as the peak emission
maximum allowed over the average value when using DCCF.
(b) Unless otherwise specified, on any frequency or frequencies above 1000
MHz, the radiated emission limits are based on the use of measurement
instrumentation employing an average detector function. Unless otherwise
specified, measurements above 1000 MHz shall be performed using a
minimum
resolution bandwidth of 1 MHz. When average radiated emission
measurements
are specified in this part, including average emission measurements
below
1000 MHz, there also is a limit on the peak level of the radio frequency
emissions. Unless otherwise specified, e.g., see § § 15.250, 15.252,
15.253(d), 15.255, 15.256, and 15.509 through 15.519 of this part,
the limit
on peak radio frequency emissions is 20 dB above the maximum permitted
average emission limit applicable to the equipment under test. This peak
limit applies to the total peak emission level radiated by the
device, e.g.,
the total peak power level. Note that the use of a pulse desensitization
correction factor may be needed to determine the total peak emission
level.
The instruction manual or application note for the measurement
instrument
should be consulted for determining pulse desensitization factors, as
necessary.
