emission level in the preliminary test. The Analyzer / Receiver scanned from 30MHz to 
300MHz. Emissions were scanned and measured rotating the EUT to 360 degrees, varying 
cable placement and positioning the antenna 1 to 4 meters above the ground plane, in both the 
vertical and the horizontal polarization, to maximize the emission reading level. Record at 
least six highest emissions. Emission frequency, amplitude, antenna position, polarization 
and turntable position were recorded into a computer in which correction factors were used to 
calculate the emission level and compare reading to the applicable limit and only QP reading 
is presented. The test data of the worst-case condition(s) was recorded.
