III. Conducted/Radiated Emissions Requirements (EMI)
3.1 General:
The conducted emissions test from 150KHz to 30MHz is employed to the
power line through a LISN (Line Impedance Stabilization Network). The
limits are 66-56dBuV(QP) / 56-46dBuV(Average), decreases linearly with the
logarithm for 0.15-0.50MHz; 56dBuV(QP)/ 46dBuV(Average) for
0.50MHz-5MHz; 60dBuV(QP) / 50dBuV(Average) for 5-30MHz.
The conducted emissions test from 150KHz to 30MHz is employed to the
telecommunication port through a ISN (Impedance Stabilization Network) or
Current Probe . The Voltage limits are 84-74dBuV(QP) / 74-64dBuV(Average),
decreases linearly with the logarithm for 0.15-0.50MHz; 74dBuV(QP)/
64dBuV(Average) for 0.50MHz-30MHz; Current limits are 40-30dBuV(QP) /
30-20dBuV(Average), decreases linearly with the logarithm for
0.15-0.50MHz; 30dBuV(QP)/ 20dBuV(Average) for 0.50MHz-30MHz;
The radiated emissions test is made at a 10 meters open site from 30MHz
to 1000MHz. The object of this test is to investigate the emissions from the
EUT in order to suppress interference to the environment. The limits are
30dBuV/m(QP) for 30-230MHz; 37dBuV/m(QP) for 230-1000MHz.
3.2 Test Specifications:
Requirement Comment Result (Pass/Fail)
EN 55022 Class B Conducted Emission 0.15-30 MHz
(Main Power Port) Pass
EN 55022 Class B Conducted Emission 0.15-30 MHz
(Telecommunication Port) N/A
EN 55022 Class B Radiated Emission 30-1000 MHz Pass
3.3 Setup:
The EUT is placed on a support of non-metallic, the height of which is
0.8m above the ground. For the conducted test, a LISN is used as a
matching network to the measuring receiver. The EUT is rotated and the
antenna's height vary between 1m and 4m for horizontal and vertical
polarization to obtain the maximum reading during the radiated test.
