7.7 CONDUCTED BAND EDGE MEASUREMENT
7.7.1         Applicable Standard

According to FCC Part 15.247(d) and KDB 558074 D01 15.247 Meas Guidance v05r02 Section 8.7.

7.7.2   Conformance Limit

In any 100 kHz bandwidth outside the frequency band in which the spread spectrum or digitally modulated
intentional radiator is operating, the radio frequency power that is produced by the intentional radiator shall
be at least 20 dB below that in the 100 kHz bandwidth within the band that contains the highest level of the
desired power, based on either an RF conducted or a radiated measurement, provided the transmitter
demonstrates compliance with the peak conducted power limits. If the transmitter complies with the
conducted power limits based on the use of RMS averaging over a time interval, as permitted under
paragraph (b)(3) of this section, the attenuation required under this paragraph shall be 30 dB instead of 20
dB.


7.7.3   Measuring Instruments

The Measuring equipment is listed in the section 6.3 of this test report.

7.7.4   Test Setup

Please refer to Section 6.1 of this test report.

7.7.5   Test Procedure

The testing follows FCC KDB 558074 D01 15.247 Meas Guidance v05r02 Section 8.7.
The RF output of EUT was connected to the spectrum analyzer by RF cable and attenuator.
The path loss was compensated to the results for each measurement.
Set to the maximum power setting and enable the EUT transmit continuously.
The EUT was operating in controlled its channel.
Set RBW to 100 kHz and VBW of spectrum analyzer to 300 kHz with a convenient frequency span including
100 kHz bandwidth from band edge.
Measure the highest amplitude appearing on spectral display and set it as a reference level. Plot the graph
with marking the highest point and edge frequency.
Repeat above procedures until all measured frequencies were complete.

7.8 SPURIOUS RF CONDUCTED EMISSIONS
7.8.1   Conformance Limit

1. Below -20dB of the highest emission level in operating band.
2. Fall in the restricted bands listed in section 15.205. The maximum permitted average field strength is
listed in section 15.209.


7.8.2   Measuring Instruments

The Measuring equipment is listed in the section 6.3 of this test report.

7.8.3   Test Setup

Please refer to Section 6.1 of this test report.

7.8.4   Test Procedure

The Spurious RF conducted emissions compliance of RF radiated emission should be measured by
following the guidance in ANSI C63.10-2013 with respect to maximizing the emission by rotating the EUT,
measuring the emission while the EUT is situated in three orthogonal planes (if appropriate), adjusting the
measurement antenna height and polarization etc. Set RBW=100kHz and VBW= 300KHz to measure the
peak field strength , and measure frequency range from 9KHz to 26.5GHz.

7.8.5   Test Results

Remark: The measurement frequency range is from 9KHz to the 10th harmonic of the fundamental
frequency. The lowest, middle and highest channels are tested to verify the spurious emissions and bandege
measurement data.
