7.3 Test Procedure

Prior to measurement of DUT radiated emissions, test setup ambient levels (i.e. all equipment energized except DUT)

shall be verified to be 6 db or more below the specified requirements listed in Table 7-2. If this requirement is not

met, testing shall not proceed until the associated test setup issues are resolved. Plots of the test setup ambient shall be

included in the test report. Test setup ambient measurements shall be performed using a 9/10 kHz MBW with peak

detection except for bands EU1, G1, and G8, which require use of average detection. All test setup ambient

measurements shall be performed using only vertical polarization of the measurement antenna

b) Measurement of DUT radiated emissions shall be performed over all frequency bands listed in Tables 7-1 and 7-2. At

measurement frequencies ≥ 30 MHz, measurements shall be performed in both vertical and horizontal antenna

polarizations.

c) When assessing DUT performance per Level 1 and Level 2 above 30 MHz (except band G8), measurements may be

initially performed using 120 kHz MBW with peak detection along with the measurement system requirements

delineated in Table 7-5 (Limit A). This approach facilitates reduction in the overall measurement time. If the resulting

DUT emission levels are below Limit A (Level 1 and Level 2(Peak)), the test data may be submitted as the final result.

When using 120 kHz MBW with PK detection to assess DUT emissions per Level 2, Limit A (Peak), measurement

system ambient requirements as delineated in step a) may be waived.

If DUT emission levels, measured in step c), are above any of the individual band requirements, additional

measurements shall be performed using the measurement system requirements listed in Tables 7-4 and 7-5. This

process is illustrated in Figures 7-3 and 7-4. Contact the FMC EMC department regarding questions and/or

clarifications with respect to this process.

 When assessing compliance to Level 2, Limit A, Peak or Average measurements shall be performed over the

entire frequency band(s), where the emissions from step c) exceeded the limit. Separate measurements to

demonstrate compliance to both PK and AVG limits is not required.

 When assessing compliance to Level 2, Limit B, measurements are limited to individual frequencies where the

emissions from step c) exceeded the limit.

d) Tests shall be repeated for all DUT operating modes delineated in the component EMC test plan.
