6. EMISSION TESTS

6.1 MAIN TERMINAL CONTINUOUS DISTURBANCE VOLTAGE

6.1.1 Test setup

The EUT was placed on the floor as typical applications. Power was fed to the EUT through a 50 Ω /

50 μH + 5 Ω Artificial Mains Network (AMN). The ground plane was electrically bonded to the referenc

e ground system and all power lines were filtered from ambient.

The test set-up photos are included in appendix I.

Used Software for measurement is EMC 32 supplied by Rohde & Schwarz.

6.1.2 Test Result

Date of Test 2018-11-06 Temperature (17.0 ~ 21.2) °C

Test Mode Mode #1 ~ #9 Relative humidity (47.8 ~ 49.5) % R.H.

Frequency range 0.15 MHz ~ 30 MHz Resolution bandwidth 9 kHz

Test Result Pass Tested By Im, Jin-young

6.1.3 Sample Calculated Example

At 3.638 MHz CAV Limit = 60.0 dBµV

Correction Factor (C. Factor) of LISN, Pulse Limiter and cable loss at 3.638 MHz = 10.3 dB

CAV Reading from the Test receiver = 43.5 dBµV

(Calculated value for system losses by software EMC32 manufactured by Rohde & Schwarz)

Therefore CAV Margin = 60 - 43.5 = 16.5 so the EUT has 16.5 dB margin at 3.638 MHz

6.2 CONDUCTED COMMON MODE DISTURBANCE AT TELECOMMUNICATION PORTS

6.2.1 Test setup

The EUT was placed on the floor as typical applications. Power was fed to the EUT through a 50 Ω /

50 μH + 5 Ω Artificial Mains Network (AMN). Telecommunication line for the EUT connected to associat

e equipment through an Impedance Stabilization Network (ISN) which has a common mode termination

impedance of 150 ohms to the telecommunication port under test. The ground plane was electrically bo

nded to the reference ground system and all power lines were filtered from ambient.

The test set-up photos are included in appendix II.

Used Software for measurement is EMC 32 supplied by Rohde & Schwarz.

6.2.2 Test Result

Date of Test 2018-11-06 Temperature 21.2 °C

Test Mode Mode #4, and Mode #5 Relative humidity 49.5 % R.H.

Frequency range 0.15 MHz ~ 30 MHz Resolution bandwidth 9 kHz



At 1.794 MHz CAV Limit = 64.0 dBµV

Correction Factor (C. Factor) of LISN, Pulse Limiter and cable loss at 3.122 MHz = 9.3 dB

CAV Reading from the Test receiver = 25.3 dBµV

(Calculated value for system losses by software EMC32 manufactured by Rohde & Schwarz)

Therefore Q.P Margin = 64.0 – 25.3 = 38.7 so the EUT has 38.7 dB margin at 1.794 MHz




6.2.4 Test data

Mode #4 CAT 5 (100 Mbps)




Mode #5 CAT 6 (1 000 Mbps)




6.3 RADIATED ELECTROMAGNETIC FIELD

6.3.1 Test setup

The radiated emissions measurements were on the 10 m, semi anechoic chamber. The EUT and all local

support equipments were placed on a non-conductive turntable approximately 0.1 m above the ground plane.

The frequency spectrum from 30 MHz to 1 000 MHz was scanned and emission levels maximized at each

frequency recorded. The system was rotated 360°, and the antenna was varied in height between 1.0 m and

4.0 m in order to determine the maximum emission levels. This procedure was performed for both horizontal

and vertical polarization of the receiving antenna.

The test set-up photos are included in appendix III.

Used Software for measurement is manufactured by TSJ.

6.3.2 Test result

Date of Test 2018-11-05 Test Mode Mode #1 ~ #9

Temperature (17.4 ~ 20.8) °C Relative humidity (46.5 ~ 51.2) %R.H.

Frequency range 30 MHz ~ 1 000 MHz Resolution bandwidth 120 kHz

Measurement distance 10 m Test Result Pass

Temperature (21.0 ~ 22.3) °C Relative humidity (47.2 ~ 50.8) %R.H.

Frequency range 1 000 MHz ~ 6 000 MHz Resolution bandwidth 1 MHz



At 120.210 MHz Limit = 40.0 dBµV/m

Result =Receiver reading value + Antenna Factor + Cable Loss - Pre-amplifier gain = 32.7 dBµV/m

Margin = Limit - Result =40.0 – 32.7 = 7.3 so the EUT has 7.3 dB margin at 120.210 MHz




6.3.4 Test data

Mode #1 Frequency range_30 MHz ~ 1 000 MHz

NOTE: Quasi-Peak was not measured, because Peak values met Quasi-Peak limit.




Mode #1 Frequency range_1 000 MHz ~ 6 000 MHz [Peak Data]

NOTE: Average mode was not measured, because Peak values were under the Average limit.









































Note: This test result is for reporting purpose only.

Signal lines–Capacitive Coupling Clamp(CCC)

Lines for test AC mains of the EUT

Type of line Unshielded, AC/DC Adapter input line


7.3.2 Test setup

The EUT and all cables to the EUT were placed on non-metallic support 0.1 m above a reference grou

nd plane (RGP) and were put into operation according to the specified operating mode.

The minimum distance between the EUT and all other conductive structures (e.g. the walls of a shielde

d room), except the ground reference plane shall be more than 0.5 m. Unless otherwise specified in th

e product standard or the product family standard, the length of the signal and power lines between th

e coupling device and the EUT shall be 0.5 m ± 0.05 m. If the manufacturer provides a non-detachabl

e supply cable more than 0.5 m ± 0.05 m long with the equipment, the excess length of this cable sh

all be folded to avoid a flat coil and situated at a distance of 0.1 m above the ground reference plane.

The test set-up photos are included in appendix VII.
