8. Field Strength of Spurious Emissions

8.1 Standard Applicable

According to §15.247(d), 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. Attenuation below the
general limits specified in §15.209(a) is not required. In addition, radiated emissions 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).

The emission limit in this paragraph is based on measurement instrumentation employing an average detector. The
provisions in §15.35 for limiting peak emissions apply. Spurious Radiated Emissions measurements starting
below or at the lowest crystal frequency.

8.2 Test Procedure

The setup of EUT is according with per ANSI C63.10-2013 measurement procedure. The specification used was
with the FCC Part 15.205 15.247(a) and FCC Part 15.209 Limit.
The external I/O cables were draped along the test table and formed a bundle 30 to 40 cm long in the middle.
The spacing between the peripherals was 10 cm.

8.3 Corrected Amplitude & Margin Calculation

The Corrected Amplitude is calculated by adding the Antenna Factor and the Cable Factor, and subtracting the
Amplifier Gain from the Amplitude reading. The basic equation is as follows:

                   Corr. Ampl. = Indicated Reading + Ant. Factor + Cable Loss – Ampl. Gain

The “Margin” column of the following data tables indicates the degree of compliance with the applicable limit.
For example, a margin of -6dBV means the emission is 6dBV below the maximum limit. The equation for
margin calculation is as follows:

                                   Margin = Corr. Ampl. – FCC Part 15 Limit

10. Conducted Emissions

10.1 Test Procedure

The setup of EUT is according with per ANSI C63.4-2014 measurement procedure. The specification used was
with the FCC Part 15.207 Limit.
The external I/O cables were draped along the test table and formed a bundle 30 to 40 cm long in the middle.
The spacing between the peripherals was 10 cm.
