8 Test Setup Details
All antenna port conducted measurements were performed on a bench-top setup consisting of a
spectrum analyzer, RF attenuator, and pre-characterized RF cables.
The correction factors between the EUT and the spectrum analyzer were added internally in the
analyzer settings. The plots displayed takes into account these correction factors.

9.4 Power Spectral Density
Test Requirement:
FCC CFR 47 Rule Part 15.407 (a)
ISED RSS-247 [6.2]
Test Method:
Measurements were performed according to the procedures defined in KDBs 789033- General
UNII Test Procedures New Rules v02r01, 662911 D01 Multiple Transmitter Output v02r01, and
ANSI C63.10 2013.
Spectrum Analyzer settings for devices operating in the bands 5.15 – 5.25 GHz, 5.25 –
5.35GHz, and 5.47 – 5.725GHz:
RBW= 1 MHz
VBW= 3 MHz
Detector = RMS
Trace Mode= Average over 100 traces
Sweep time= Auto
Sweep Point ≥ 2*Span/RBW
Span= large enough to encompass the 26-dB Emission Bandwidth or alternatively the 99%
Occupied Bandwidth. Use the peak marker function to identify the Maximum Power Spectral
Density
Spectrum Analyzer settings for devices operating in the bands 5.725 – 5.85 GHz:
RBW= 100 kHz
VBW= Greater than or equal to 3 x RBW
Detector = RMS
Trace Mode= Average over 100 traces
Sweep time= Auto
Sweep Point ≥ 2*Span/RBW
Span= large enough to encompass the 26-dB Emission Bandwidth or alternatively the 99%
Occupied Bandwidth. Use the peak marker function to identify the Maximum Power Spectral
Density
Offset is added if measurements are performed using a reduced resolution bandwidth 100 kHz,
add 10* log (500KHz/RBW USED) to the measured result.
