Remark：  

(1) Reading in which marked as QP or Peak means measurements by using are Quasi-Peak 

Mode or Peak Mode with Detector BW=120KHz；SPA setting in RBW=120KHz, VBW 
=120KHz, Swp. Time = 0.3 sec./MHz。 

(2) All readings are Peak unless otherwise stated QP in column of『Note』. Peak denotes 

that the Peak reading compliance with the QP Limits and then QP Mode measurement 
didn‘t perform。 

(3) Measuring frequency range from 30MHz to 1000MHz。 
(4) If the peak scan value lower limit more than 20dB, then this signal data does not show 

in table。 

(5) “N/A” denotes test is not applicable in this Test Report

4.4.3 TEST PROCEDURE 

a. The EUT was placed on the top of a wooden table 0.8 meters above the ground and operated 

to produce the maximum harmonic components under normal operating conditions. 

b. The classification of EUT is according to section 5 of EN 61000-3-2: 2006.The EUT is 

classified as follows: 

  Class A: Balanced three-phase equipment, Household appliances excluding equipment as 

Class D, Tools excluding portable tools, Dimmers for incandescent lamps, audio 
equipment, equipment not specified in one of the three other classes. 

  Class B: Portable tools. Arc welding equipment which is not professional equipment. 
  Class C: Lighting equipment. 
  Class D: Equipment having a specified power less than or equal to 600 W of the following 

types: Personal computers and personal computer monitors and television 
receivers. 

c. The correspondent test program of test instrument to measure the current harmonics 

emanated from EUT is chosen. The measure time shall be not less than the time necessary for 
the EUT to be exercised. 

d. For the actual test configuration, please refer to the related Item –Block Diagram of system 

tested (please refer to 3.3).
