3.4.Configuration of EUT on Test
The following equipment are installed on Power Line Conducted Emission Test to meet the
commission requirement and operating regulations in a manner which tends to maximize its
emission characteristics in a normal application.
3.4.1. CaptionCall Wireless Router 2 (EUT)
Model No. : CR2
Serial No. : N/A
3.4.2. Support Equipment: As Tested Supporting System Details, in Section 2.2.

3.5.Operating Condition of EUT
3.5.1. Setup the EUT and simulator as shown as Section 3.2.
3.5.2. Turn on the power of all equipments.
3.5.3. PC run test software to control EUT work in Tx (WiFi 2.4GHz) mode.

3.6.Test Procedure
The EUT was placed on a non-metallic table, 80cm above the ground plane. The EUT Power
Via PC connected to the power mains through a line impedance stabilization network (L.I.S.N.
1#). This provides a 50 ohm coupling impedance for the EUT (Please refer the block diagram of
the test setup and photographs). The AC line are checked to find out the maximum conducted
emission. In order to find the maximum emission levels, the relative positions of equipment and
all of the interface cables shall be changed according to ANSI C63.10: 2013 on Conducted
Emission Test.

The bandwidth of test receiver (R & S ESCI) is set at 9kHz.

The frequency range from 150kHz to 30MHz is checked.

3.7.Power Line Conducted Emission Test Results
PASS. (All emissions not reported below are too low against the prescribed limits.)

4.5.Operating Condition of EUT
4.5.1. Setup the EUT and simulator as shown as Section 4.2.
4.5.2. Turn on the power of all equipments.
4.5.3. Let EUT work in Tx(WiFi 2.4GHz) mode

4.6.Test Procedure
EUT and its simulators are placed on a turn table, which is 0.8 meter high above ground for
frequency 30MHz~1000MHz, 1.5 meter high above ground for frequency above 1GHz and put
the absorbing with 2.4m(L)*2.4m(W)*0.3m(H) on the ground. The turn table can rotate 360
degrees to determine the position of the maximum emission level. Power on the EUT and let it
working in test mode, then test it.EUT is set 3 meters away from the receiving antenna, which is
mounted on a antenna tower. The antenna can be moved up and down between 1 meter and 4
meters to find out the maximum emission level. Broadband antenna (calibrated bilog antenna) is
used as receiving antenna for frequency 30MHz~1000MHz, and the Horm antenna is used as
receiving antenna for frequency above 1GHz. Both horizontal and vertical polarization of the
antenna are set on test.

This test was performed with EUT in X, Y, Z position, and the worse case was found when EUT
in X position as test photo indicated.

The bandwidth of the EMI test receiver (R&S ESR7) is set at 120kHz for frequency range from
30MHz to 1000 MHz.

The bandwidth of the Spectrum’s VBW is set at 3MHz and RBW is set at 1MHz for peak
emissions measurement above 1GHz and 1MHz RBW, 10Hz VBW for average emissions
measure above 1GHz

The frequency range from 30MHz to 10th harmonic (25GHz) are checked. and no any
emissions were found from 18GHz to 25GHz, So the radiated emissions from 18GHz
to 25GHz were not record.
4.7.Radiated Emission Test Results
PASS.

All the emissions from 30MHz to 25 GHz were comply with 15.209 limits.

Note: For emissions above 1GHz, if peak level comply with average limit, then the average level
is deemed to comply with average limit.
