General Information

General Description of EUT

Description of Test Modes

Transmitting mode: Keep the EUT in continuously transmitting mode

Remark: EUT uses new battery during the test. The test voltage was tuned from 85% to 115% of the nominal rated supply voltage, and it was found that the worst case was under the nominal rated supply condition. Therefore, the report only shows data under this condition.

Conducted Emission Measurement

Test Requirement: FCC Part15 C Section 15.207

Test Method: ANSI C63.10:2013

Test Frequency Range: 150KHz to 30MHz

Receiver setup: RBW=9KHz, VBW=30KHz, Sweep time=auto

Power Line Conducted Emission Limits

Note: (1) *Decreases with the logarithm of the frequency.

Test Procedure

a. The EUT was placed 0.8 meters from the horizontal ground plane with EUT being connected to the power mains through a line impedance stabilization network (LISN). All other support equipments powered from additional LISN(s). The LISN provides 50 Ohm/ 50uH of coupling impedance for the measuring instrument.

b. Interconnecting cables that hang closer than 40 cm to the ground plane shall be folded back and forth in the center forming a bundle 30 to 40 cm long.

c. I/O cables that are not connected to a peripheral shall be bundled in the center. The end of the cable may be terminated, if required, using the correct terminating impedance. The overall length shall not exceed 1 m.

d. LISN at least 80 cm from nearest part of EUT chassis.

e. For the actual test configuration, please refer to the related Item – EUT Test Photos.

Radiated Emission Measurement

Test Requirement: FCC Part15 C Section 15.209

Test Method: ANSI C63.10:2013

Test Frequency Range: 9kHz to 25GHz

Test site: Measurement Distance: 3m

Radiated Emission Limits

Limits of Radiated Emission Measurement (at 3M)

Notes: (1) The limit for radiated test was performed according to FCC PART 15C. (2) The tighter limit applies at the band edges. (3) Emission level (dBuV/m)=20log Emission level (uV/m).

Test Procedure

Above 1GHz test procedure as below:

a. The EUT was placed on the top of a rotating table 1.5 meters above the ground at a 3 meter camber. 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 antenna height 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 rota table was turned from 0 degrees to 360 degrees to find the maximum reading.

e. The test-receiver system was set to Peak Detect Function and Specified Bandwidth with Maximum Hold Mode.

f. If the emission level of the EUT in peak mode was 10dB lower than the limit specified, then testing could be stopped and the peak values of the EUT would be reported. Otherwise the emissions that did not have 10dB margin would be re-tested one by one using peak, quasi-peak or average method as specified and then reported in a data sheet.

g. Test the EUT in the lowest channel, the Highest channel

Note: Both horizontal and vertical antenna polarities were tested and performed pretest to three orthogonal axis. The worst case emissions were reported
