levels were recorded for reference of the final test.
Procedure of Final Test
EUT and support equipment were set up on the test bench as per the configuration with
highest emission level in the preliminary test. A scan was taken on both power lines,
recording at least the six highest emissions. Emission frequency and amplitude were recorded
into a computer in which correction factors were used to calculate the emission level and
compare reading to the applicable limit. The test data of the worst-case condition(s) was
recorded.
