Harman Multimedia JBL OnStage EMC Test Report
2004 050310 EMC
17 of 80
4.4. Power Line Harmonics: EN 61000-3-2 (2000)
This test evaluates the potential for the EUT to cause distortion on the AC power lines. Testing was performed
in accordance with EN 61000-3-2. It 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.
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

section and photographs of the test set-up provided in this report.
4.5. Power Line Fluctuations/Flicker: EN 61000-3-3 (1995)
Testing was performed in accordance with EN 61000-3-3. It 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 in addition to the test results
section and photographs of the test set-up provided in this report.
