8.1 Emissions Test Procedures
The following is a description of the test procedure used by Intertek Testing Services
in the measurements of EUT operating under Part 15, Subpart B rules.
The test set-up and procedures described below are designed to meet the
requirements of ANSI C63.4 - 2003.
The equipment under test (EUT) is placed on a wooden turntable which is four
feet in diameter and approximately one meter in height above the ground
plane. During the radiated emissions test, the turntable is rotated and any
cables leaving the EUT are manipulated to find the configuration resulting in
maximum emissions. The EUT is adjusted through all three orthogonal axes to
obtain maximum emission levels. The antenna height and polarization are
varied during the testing to search for maximum signal levels. The height of the
antenna is varied from one to four meters.
Detector function for radiated emissions from the frequency band 30MHz to
1GHz is in QP mode and RBW setting is 120kHz. Detector function for
radiated emissions for frequency band above 1GHz, both peak and AV
detectors shall be used to measure the emissions and the peak limit is 20dB
above the maximum permitted average emission limit and RBW setting is
1MHz. Detector function for conducted emissions are in QP & AV mode and
IFBW setting is 9kHz from the frequency band 150kHz to 30MHz.
For radiated emission, the frequency range scanned is 30MHz to 2GHz. For
line-conducted emissions, the range scanned is 150kHz to 30MHz.
