5 Peak Conducted Output Power Measurements
5.1 Test Method
Antenna port conducted measurements were performed on a bench-top setup consisting of a
spectrum analyzer, power meter (as necessary), splitters/combiners (as necessary),
attenuators, and pre-characterized RF cables.

The correction factors between the EUT and the Spectrum Analyzer is added internally in the
Analyzer settings. The plots displayed accounts for these correction factors.

Spectrum Analyzer Settings:
Peak Power Measurements:
Method of KDB 558074.
RBW= 1 MHz
VBW= 3 MHz
Trace Mode= Peak Detector (Max Hold)
Sweep time= Auto
Span= 3 MHz

EIRP was calculated based on the following formula:

6 SAR Test Exclusion
6.1 FCC

        SAR Test Exclusion Criteria
According to FCC KDB 447498 D01 General RF Exposure Guidance v06 (Oct 2015) Section
4.3.1, the 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation
distances ≤ 50 mm is defined as

                  .                  ,                              ,
                                                                             [√f(GHz)] ≤ 3.0
                             .                        ,

where

• f(GHz) is the RF channel transmit frequency in GHz
• Power and distance are rounded to the nearest mW and mm before calculation
• The result is rounded to one decimal place for comparison


        FCC SAR Test Exclusion Evaluation
The EUT was excluded from routine SAR evaluation measurements, since the SAR test
exclusion criteria were met. The min. separation distance of 5mm is used for the calculation.

6.2 IC

        SAR Test Exclusion Criteria
For devices with a separation distance <5mm, SAR evaluation is exempt for transmitters
operating with an output power < 4mW at 2450 MHz (RSS-102 Table 1).

        IC SAR Test Exclusion Evaluation
The EUT was excluded from routine SAR evaluation measurements, since the SAR test
exclusion criteria were met.
