EN 55022 also specifies limits and methodology for radiated emissions testing. Initially, the primary emission 
frequencies are identified inside a shielded chamber by positioning a broadband receive antenna one meter from 
the EUT. Next, the EUT and associated system are placed on a turntable on a ten-meter open area test site 
(OATS) with known attenuation characteristics and all significant radiated emissions are recorded. To ensure 
that the maximum emission at each discrete frequency of interest is observed, the receive antenna is varied in 
height from one to four meters and rotated to produce horizontal and vertical polarities, and the turntable is also 
rotated to determine the worst emitting configuration. The numerical results of the test are included herein to 
demonstrate compliance. The numerical results of the test are included herein to demonstrate compliance.  
 
The numerical results that are applied to the emissions limits are arrived as demonstrated by the example below: 
 
 
 
 
 
 
 
 
A. Frequency Measured in MHz. 
 
B. Meter Reading: Emission Amplitude as measured with the antenna in Vertical polarity in dBμV, this is from 
the EMI receiver or Spectrum Analyzer. 
 
C. Meter Reading: Emission Amplitude as measured with the antenna in Horizontal polarity in dBμV, this is 
from the EMI receiver or Spectrum Analyzer. 
 
D. Detector used: Q for Quasi-Peak, A for average, P for peak. 
 
E. EUT Side F/L/R/B: Side of EUT facing the receiving antenna. Front, Left, Right, Back. If not noted, 
emission did not peak in a significant manner to discriminate which side of the EUT emitted the emission. 
 
F. Ant. Height m: Antenna height in meters of strongest emission measured when raised from 1 to 4 meters. 
 
G. Max Reading: Max meter reading of B vertical and C horizontal in dBμV. 
 
H. Corrected Reading: Corrected Reading in dBμV/m; Max Reading corrected for cable loss (dB), antenna 
factor (dBV/m) and preamplifier gain (dB). 
 
I.  Spec limit: Specification Limit at the measured frequency in dBμV/m. 
 
J. CR/SL Diff.: Difference in dB of Corrected Reading and Specification Limit, negative results indicate a 
margin value below the specification limit. 
 
K. Pass Fail: Result; EUT does or does not comply at this frequency.

EN 61000-3-2 is applicable to electrical and electronic equipment having an input current up to and including 
16 amps per phase, and intended to be connected to public low-voltage distribution systems. The objective of 
this standard is to set limits for harmonic emissions of equipment onto the AC Power Line.  

 
Basic requirements of the AC source include a ± 2% voltage regulation and a ± 0.5% frequency limit. A low 
distortion sine wave output is required to ensure that the AC source does not adversely contribute distortion to 
the load, meeting the following limits: 

 

o

  0.9% for 3

rd

 order harmonics 

o

  0.4% for 5th order harmonics 

o

  0.3% for 7th order harmonics 

o

  0.2% for 9th order harmonics 

o

  0.2% for even harmonics of order 2 to 10 

o

  0.1% for odd harmonic order from 11 to 40 

 
For further information, please refer to the technical sections in the EN 61000-3-2 publication in addition to the 
test results section and photographs of the test set-up provided in this report. 
 
 

 
EN 61000-3-3 is applicable to household appliances and similar electrical and electronic equipment having an 
input current up to and including 16 amps per phase. The objective of this standard is to set limits for voltage 
fluctuations of equipment within its scope, and ensures that home appliances and certain other electrical 
equipment do not adversely affect lighting equipment when connected to the same utility power line. Large 
current variations combined with high utility line power impedance can cause excessive changes in the AC 
supply voltage. If these voltage changes are repeated at short intervals, objectionable fluctuations of luminance 
(flicker) could be generated in illumination sources connected to the same utility line network. 

 
This test requires an AC power source with a standard impedance network and a power analyzer. 
Measurements of steady state and fluctuating harmonics, along with flicker and voltage deviations, are 
conducted using a power analyzer, often called a “flickermeter.” 

 
For further information, please refer to the technical sections in the EN 61000-3-3 publication in addition to the 
test results section and photographs of the test set-up provided in this report.
