1 2) Sequence of testing 30 to 1 GHz Setup: --- The equipment was set up to simulate a typical usage like described in the user manual or described by manufacturer. --- If the EUT is a tabletop system, a table with 0.8 m height is used, which is placed on the ground plane. --- If the EUT is a floor standing device, it is placed on the ground plane with insulation between both. --- Auxiliary equipment and cables were positioned to simulate normal operation conditions --- The AC power port of the EUT (if available) is connected to a power outlet below the turntable. --- The measurement distance is 3 meter. --- The EUT was set into operation. Premeasurement: --- The turntable rotates from 0 to 315 using 45 steps. --- The antenna is polarized vertical and horizontal. --- The antenna height changes from 1 to 3 meter. --- At each turntable position, antenna polarization and height the analyzer sweeps three times in peak to find the maximum of all emissions. Final measurement: --- The final measurement will be performed with minimum the six highest peaks. --- According to the maximum antenna and turntable positions of premeasurement the software maximize the peaks by changing turntable position (± 45 ) and antenna movement between 1 and 4 meter. --- The final measurement will be done with QP detector with an EMI receiver. --- The final levels, frequency, measuring time, bandwidth, antenna height, antenna polarization, turntable angle, correction factor, margin to the limit and limit will be recorded. Also a plot with the graph of the premeasurement with marked maximum final measurements and the limit will be stored. Page 41 of 74

If the transmitter complies with the conducted power limits based on the use of RMS averaging over a time interval, as permitted under paragraph (b)(3) of this section, the attenuation required under this paragraph shall be 30 instead of 20. Attenuation below the general limits specified in (a) is not required.

The use of a permanently attached antenna or of an antenna that uses a unique coupling to the intentional radiator shall be considered sufficient to comply with the provisions of this Section. The manufacturer may design the unit so that a broken antenna can be re-placed by the user, but the use of a standard antenna jack or electrical connector is prohibited. This requirement does not apply to carrier current devices or to devices operated under the provisions of Sections , , , , or Further, this requirement does not apply to intentional radiators that must be professionally installed, such as perimeter protection systems and some field disturbance sensors, or to other intentional radiators which, in accordance with Section 15.31(d), must be measured at the installation site.
