Test Procedures
For Radiated emission below 30 MHz
a. The EUT was placed on the top of a rotating table 0.8 meters above the ground at a 3 meter chamber
room. The table was rotated 360 degrees to determine the position of the highest radiation.
b. The EUT was set 3 meters away from the interference-receiving antenna, which was mounted on the top
of a variable-height antenna tower.
c. Both Parallel, perpendicular, and ground-parallel orientations of the antenna are set to make the
measurement.
d. For each suspected emission, the EUT was arranged to its worst case and the rotatable table was turned
from 0 degrees to 360 degrees to find the maximum reading.
e. The test-receiver system was set to Quasi-Peak Detect Function and Specified Bandwidth with Maximum
Hold Mode.
Note:
1. The resolution bandwidth and video bandwidth of test receiver/spectrum analyzer is 9 kHz at frequency
below 30 MHz.
For Radiated emission above 30 MHz
a. The EUT was placed on the top of a rotating table 0.8 meters (for 30 MHz ~ 1 GHz) / 1.5 meters (for
above 1 GHz) above the ground at 3 meter chamber room for test. The table was rotated 360 degrees to
determine the position of the highest radiation.
b. The EUT was set 3 meters away from the interference-receiving antenna, which was mounted on the top
of a variable-height antenna tower.
c. The height of antenna is varied from one meter to four meters above the ground to determine the
maximum value of the field strength. Both horizontal and vertical polarizations of the antenna are set to
make the measurement.
d. For each suspected emission, the EUT was arranged to its worst case and then the antenna was tuned to
heights from 1 meter to 4 meters and the rotatable table was turned from 0 degrees to 360 degrees to find
the maximum reading.
e. The test-receiver system was set to quasi-peak detect function and specified bandwidth with maximum
hold mode when the test frequency is below 1 GHz.
f.
The test-receiver system was set to peak and average detected function and specified bandwidth with
maximum hold mode when the test frequency is above 1 GHz. If the peak reading value also meets
average limit, measurement with the average detector is unnecessary.
Note:
1. The resolution bandwidth and video bandwidth of test receiver/spectrum analyzer is 120 kHz for
Quasi-peak detection (QP) at frequency below 1 GHz.
2. The resolution bandwidth of test receiver/spectrum analyzer is 1 MHz and the video bandwidth is 3 MHz
for Peak detection (PK) at frequency above 1 GHz.
3. The resolution bandwidth of test receiver/spectrum analyzer is 1 MHz and the video bandwidth is ≥ 1/T
(Duty cycle < 98 %) or 10 Hz (Duty cycle ≥ 98 %) for Average detection (AV) at frequency above 1 GHz.
4. All modes of operation were investigated and the worst-case emissions are reported.

Remarks:
1. Emission Level = Read Level + Antenna Factor + Cable Loss - Preamp Factor
Margin value = Emission level – Limit value
2. The average value of fundamental frequency is: Average = Peak value + 20log(Duty cycle) Where the duty
factor is calculated from following formula:
20 log (Duty cycle) = 20 log (0.92 ms / 0.26 ms) = -12.42 dB
Please refer to the plotted duty

20 dB Bandwidth Measurement
4.2.1
Limits of 20 dB Bandwidth Measurement
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.

Test Instruments
Refer to section 4.1.2 to get information of above instrument.
4.2.4
Test Procedure
a. Check the calibration of the measuring instrument using either an internal calibrator or a known signal
from an external generator.
b. Turn on the EUT and connect it to measurement instrument. Then set it to any one convenient frequency
within its operating range. Set a reference level on the measuring instrument equal to the highest peak
value.
c.
Measure the frequency difference of two frequencies that were attenuated 20dB from the reference level.
Record the frequency difference as the emission bandwidth.
d. Repeat above procedures until all frequencies measured were complete.
4.2.5
Deviation fromTest Standard
No deviation.
