Where F is the frequency in MHz, the formulas for calculating the maximum
permitted fundamental field strengths are as follows: for the band 130-174 MHz,
uV/m at 3 meters = 56.81818(F) - 6136.3636; for the band 260-470 MHz, uV/m at
3 meters = 41.6667(F) - 7083.3333. The maximum permitted unwanted emission
level is 20 dB below the maximum permitted fundamental level.

4.5.Test Procedure
The EUT and its simulators are placed on a turntable, which is 0.8 meter high above
ground. The turntable can rotate 360 degrees to determine the position of the
maximum emission level. EUT is set 3.0 meters away from the receiving antenna,
which is mounted on an antenna tower. The antenna can be moved up and down
between 1.0 meter and 4 meters to find out the maximum emission level. Broadband
antenna (calibrated bi-log antenna) is used as receiving antenna. Both horizontal and
vertical polarizations of the antenna are set on measurement. In order to find the
maximum emission levels, all of the EUT location must be manipulated according to
ANSI C63.4 on radiated emission measurement. The EUT was tested in 3 orthogonal
planes.

The bandwidth of test receiver is set at 120 kHz in 30-1000 MHz, and 1 MHz in
1000-4000 MHz.

The frequency range from 30 MHz to 4000 MHz is checked.

Note:
1. Emissions attenuated more than 20 dB below the permissible value are not reported.
2. *: Denotes restricted band of operation.
Measurements were made using a peak detector. Any emission falling within the restricted bands of FCC
Part 15 Section 15.205 were compliance with the emission limit of FCC Part 15 Section 15.209.
3. The field strength is calculated by adding the antenna factor, high pass filter loss(if used) and cable loss,
and subtracting the amplifier gain(if any)from the measured reading. The basic equation calculation is
as follows:
Result = Reading + Corrected Factor
Where Corrected Factor = Antenna Factor + Cable Loss + High Pass Filter Loss – Amplifier Gain
4. FCC Limit for Average Measurement = 41.6667(303.9)-7083.3333 = 10996.79246 V/m =74.9 V/m
5. The spectral diagrams in appendix I display the measurement of peak values.
6. Average value= PK value + Average Factor (duty factor)

1/PW = 1/5.34ms = 0.187kHz
RBW (100 kHz) > 1/PW (0.187 kHz)

7.2.Average factor Measurement according to ANSI C63.4-2009
ANSI C63.4-2009 Section 13.4.2 Devices transmitting pulsed emissions and subject to a
limit requiring an average detector function for radiated emissions shall initially be
measured with an instrument that uses a peak detector. A radiated emission measured
with a peak detector may then be corrected to a true average using the appropriate factor
for emission duty cycle. This correction factor relates the measured peak level to the
average limit and is derived by averaging absolute field strength over one complete pulse
train that is 0.1 s, or less, in length. If the pulse train is longer than 0.1 s, the average shall
be determined from the average absolute field strength during the 0.1 s interval in which
the field strength is at a maximum.
Average factor in dB = 20 log (duty cycle)

7.4.3.Let the EUT work in TX mode measure it.

7.5.Test Procedure
7.5.1.The time period over which the duty cycle is measured is 100 milliseconds, or
the repetition cycle, whichever is a shorter time frame. The worst case
(highest percentage on) duty cycle is used for the calculation.

7.5.2.Set SPA Center Frequency = Fundamental frequency, RBW = 100 kHz, VBW
= 300 kHz, Span = 0 Hz.

7.5.3.Set EUT as normal operation.

7.5.4.Set SPA View. Delta Mark time.

7.6. Measurement Result

The duty cycle is simply the on time divided by the period:

The duration of one cycle = 21.60 ms

Effective period of the cycle = (0.36×11) + (0.69×2)ms=5.34 ms

DC = 5.34ms/21.60ms=0.247

Therefore, the average factor is found by 20log0.247=-12.14dB
