The limits on the field strength of the spurious emissions in the above table are based
on the fundamental frequency of the intentional radiator. Spurious emissions shall be
attenuated to the average (or, alternatively, CISPR quasi-peak) limits shown in this
table or to the general limits shown in 93 Section 15.209, whichever limit permits a

9.3 TEST PROCEDURE
The test site semi-anechoic chamber has met the requirement of NSA tolerance 4 dB according to the
standards: ANSI C63.10-2013. The test distance is 3m.The setup is according to the requirements in Section
13.1.4.1 of ANSI C63.10-2013 and CAN/CSA-CEI/IEC CISPR 22.
This test is required for any spurious emission that falls in a Restricted Band, as defined in Section 15.205. It
must be performed with the highest gain of each type of antenna proposed for use with the EUT.

a. The measuring distance of at 3 m shall be used for measurements at frequency up to 1GHz. For
frequencies above 1GHz, any suitable measuring distance may be used.
b. The EUT was placed on the top of a rotating table 0.8 m for below 1GHz and 1.5m for above 1GHz the
ground at a 3 meter. The table was rotated 360 degrees to determine the position of the highest
radiation.
c. The height of the equipment or of the substitution antenna shall be 0.8 m for below 1GHz and 1.5m for
above 1GHz; the height of the test antenna shall vary between 1 m to 4 m. Both horizontal and vertical
polarizations of the antenna are set to make the measurement.
d. For the radiated emission test above 1GHz:
Place the measurement antenna away from each area of the EUT determined to be a source of
emissions at the specified measurement distance, while keeping the measurement antenna aimed at
the source of emissions at each frequency of significant emissions, with polarization oriented for
maximum response. The measurement antenna may have to be higher or lower than the EUT,
depending on the radiation pattern of the emission and staying aimed at the emission source for
receiving the maximum signal. The final measurement antenna elevation shall be that which maximizes
the emissions. The measurement antenna elevation for maximum emissions shall be restricted to a
range of heights of from 1 m to 4 m above the ground or reference ground plane.
e. The initial step in collecting conducted emission data is a spectrum analyzer peak detector mode
pre-scanning the measurement frequency range. Significant peaks are then marked and then Quasi
Peak detector mode re-measured.
f. If the Peak Mode measured value compliance with and lower than Quasi Peak Mode Limit, the EUT
shall be deemed to meet QP Limits and then no additional QP Mode measurement performed.
g. For the actual test configuration, please refer to the related Item –EUT Test Photos.

Note: 1. EUT Pre-scan X/Y/Z orientation, only worst case is presented in the report(Y orientation).
2. *Calculate Average value based on Duty Cycle correction factor:
Duty Cycle=Ton/(Ton+Toff)= 13.9ms/142.8ms=0.0997=9.97%
Duty Cycle factor= 20lg (Duty Cycle) =20lg (0.0997) = -20.02dB
Average=Peak+ Duty Cycle factor
2. FCC Limit for Average Measurement = 16.6667(345) – 2833.342 = 2916.6695uV/m
=69.3dBuV/m
3. Pulse Desensitization Correction Factor
Pulse Width(PW)= 142.8ms
2/PW=2/142.8ms=0.014kHz
RBW(100kHz)>2/PW (0.014kHz),
Therefore PDCF is not needed.

Duty Cycle:
The duty cycle is simply the on time divided by the period:
The duration of one cycle = 142.8ms
TON(one hop)1=0.24ms TON(one hop)2=0.34ms,
Effective period of the cycle =0.24ms*48+0.34ms*8=14.2ms,
Duty Cycle =14.24 ms /142.8 ms =0.997=9.97%
The duration of one cycle

10. BANDWIDTH TEST
10.1 TEST PROCEDURE
The bandwidth of the emission shall be no wider than 0.25% of the center frequency for devices
operating above 70 MHz and below 900 MHz. For devices operating above 900 MHz, the
emission shall be no wider than 0.5% of the center frequency. Bandwidth is determined at the
points 20 dB down from the modulated carrier.
Limit: 345MHz*0.25%=862.5KHz
10.2 DEVIATION FROM STANDARD
No deviation.
