3.5 Spurious Emission radiated, Transmitter
Spurious emission was measured with modulation (declared by manufacturer).
The limits on the field strength of the spurious emission in the table § 15.231(b) are based on the
fundamental frequency of the intentional radiator. Spurious emission shall be attenuated to the average
(or alternatively, CISPR quasi-peak) limits shown in this table or to the general limits shown in §
15.209, whichever limit permits a higher field strength.
In addition, radiated emission which fall in the restricted bands, as defined in § 15.205(a), must also
comply with the radiated emission limits specified in § 15.209(a) (See § 15.205(c)).
SAMPLE CALCULATION OF LIMIT. All results will be updated by an automatic measuring system
in accordance to point 2.3.
Calculation of test results:
Such factors like antenna correction, cable loss, external attenuation etc. are already included in the
provided measurement results. This is done by using validated test software and calibrated test system
according the accreditation requirements.
The peak and average spurious emission plots was measured with the average limits.
In the Table being listed the critical peak and average value an exhibit the compliance with the above
calculated Limits.
