Hello All

FCC part 18 requires the use of an Average detector.  For measurements above
1GHz on a HP8593E  EMC (Spectrum) analyser,  would using a Video Average of
100 or more be equivalent to taking a measurement with an Average detector?


It has been suggested to me by a test house that this is the case,  but I
have not managed to find any rationale for this.

The setup for the Analyser in question during the measurent was as follows
if this helps:
SPAN = 2GHz,  RBW =1MHz, VBW = 3MHz, SWEEP =40ms

Many thanks.
