4.3 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 -6dBµV means the emission is 6dBµV below the maximum limit. The equation for
margin calculation is as follows:

                                  Margin = Corr. Ampl. – FCC Part 15C Limit

Note: Testing is carried out with frequency rang 9kHz to the 40GHz, which above 2th Harmonics are attenuated
more than 20dB below the permissible limits or the field strength is too small to be measured.
The measurements greater than 20dB below the limit from 9kHz to 30MHz..

5. Out of Band Emissions

5.1 Standard Applicable

Emissions radiated outside of the specified frequency bands, except for harmonics, shall be attenuated by at least
50 dB below the level of the fundamental or to the general radiated emission limits in §15.209, whichever is the
lesser attenuation.

5.2 Test Procedure

As the radiation test, set the Lowest and Highest Transmitting Channel, observed the outside band of 5725MHz to
5875MHz, than mark the higher-level emission for comparing with the FCC rules.

6. Emission Bandwidth

6.1 Standard Applicable

According to 15.215 (c), intentional radiators operating under the alternative provisions to the general emission
limits, as contained in §§15.217 through 15.257 and in Subpart E of this part, must be designed to ensure that the
20 dB bandwidth of the emission, or whatever bandwidth may otherwise be specified in the specific rule section
under which the equipment operates, is contained within the frequency band designated in the rule section under
which the equipment is operated. The requirement to contain the designated bandwidth of the emission within the
specified frequency band includes the effects from frequency sweeping, frequency hopping and other modulation
techniques that may be employed as well as the frequency stability of the transmitter over expected variations in
temperature and supply voltage. If a frequency stability is not specified in the regulations, it is recommended that
the fundamental emission be kept within at least the central 80% of the permitted band in order to minimize the
possibility of out-of-band operation.

6.2 Test Procedure

According to the ANSI 63.10-2013, the emission bandwidth test method as follows.

Remove the antenna from the EUT and then connect a low loss RF cable from the antenna port to the spectrum
analyzer.
Set span = 1MHz, centered on a transmitting channel
RBW ≥1% 20dB Bandwidth, VBW ≥RBW
Sweep = auto
Detector function = peak
Trace = max hold
All the trace to stabilize, use the marker-to-peak function to set the marker to the peak of the emission, use the
marker-delta function to measure and record the 20dB down and 99% bandwidth of the emission.

7.1 Test Procedure

The setup of EUT is according with per ANSI C63.10—2013 measurement procedure. The specification used was
with the FCC Part 15.207 Limit.
The external 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.
