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.
