When measuring emissions using a Quasi Peak detector are there any
regulations or guidance concerning the amount of time one should dwell
on a single frequency for a measurement?
This is a 'spirit and letter' matter. Emission limits are there to
protect other services. So, in the spirit of the requirements, it is
necessary to measure the 'worst case' (not the worst-worst-worst case,
as some 'EMC crusaders' advocate). For your product, that is clearly
during the 'burst' phase, even though the letter of the requirements may
not cover this situation.
