5.8 Band Edge (Restricted-band band-edge)
5.8.1 Limit
FCC §15.209&15.247(c); RSS-247, 5.5
Radiated emission outside the frequency band attenuation below the general limits specified in FCC section
15.209(a) is not required. In addition, radiated emissions which fall in the restricted bands, as defined in FCC
section 15.205(a), must also comply with the radiated emission limits specified in FCC section 15.209(a).
5.8.2 Test Setup
See section 4.4.1 for test setup description for the antenna port. The photo of test setup please refer to ANNEX B.
5.8.3 Test Procedure
The measurement frequency range is from 9 kHz to the 10th harmonic of the fundamental frequency. The Turn
Table is actuated to turn from 0° to 360°, and both horizontal and vertical polarizations of the Test Antenna are
used to find the maximum radiated power. Mid channels on all channel bandwidth verified. Only the worst RB
size/offset presented.
The power of the EUT transmitting frequency should be ignored.
All Spurious Emission tests were performed in X, Y, Z axis direction. And only the worst axis test condition was
recorded in this test report.
Use the following spectrum analyzer settings:
Span = wide enough to fully capture the emission being measured
RBW = 1 MHz for f ≥ 1 GHz, 100 kHz for f < 1 GHz
VBW ≥ RBW
Sweep = auto
Detector function = peak
Trace = max hold
For measurement below 1GHz, If the emission level of the EUT measured by the peak detector is 3 dB lower than
the applicable limit, the peak emission level will be reported, Otherwise, the emission measurement will be repeated
using the quasi-peak detector and reported.
