8.5 Emission maximization and final measurementDuring the final test the emissions are maximized to determine their highest level. After themaximization of the signals, the emission amplitude is measured using quasi-peak detectionand/or average detection, allowing for the appropriate measurement time (at least 15 s if thereading shows fluctuations close to the limit).The type of the radiated emission measurement defines the maximization process yielding thehighest signal amplitudes:
