Conducted Emission Laboratory

The Conducted Emission measurement facility at SAMEER-CEM is FCC (Federal Communication Commission) listed for the Conducted Emission measurements. The conducted emission test facility is housed inside a shielded room provided with the required vertical ground and horizontal ground reference planes, complying to the international standards such as EN55011, EN55022, CISPR 11, CISPR 22 and FCC Part 15. The facility is equipped with the state-of-the-art test and measuring equipments comprising of conducted emissiondifferent EMI receivers, Line impedance stabilization network (LISN) etc . The conducted emission measurements are carried out using the GPIB based automation sofware ensuring low uncertainty and better repetability.

EMI receivers are available covering frequency range 20 Hz - 26.5 GHz The LISNs available at the centre supports measurement on line carrying upto 200 Amps. For higher current ratings, voltage probes are available for conducted noise measurements.

Facility for the conducted emission measurement on Vehicle & Automotive sub assemblies according to various National/International standards of automotive industry like CISPR 25 and manufacturer specific standards such as FORD ES- X UU7T-1A278-ACand FIAT- 7-Z0472 are available at the centre. The facility for automotive CE measurements consists of (2000 X 1000) mm size of ground reference plane and 5uh/50W LISN with proper grounding as required by the CISPR 25, FORD ES- X UU7T-1A278-AC and standards.    

ClickThe measurements for the lighting equipments as in accordance to the International Standards CISPR 15 can be carried out at the facility.

The centre also have a Discontinuous Interference Analyzer (DIA) for click - discontinuous interference measurement confirming to CISPR 14-1 for the house holding  equipment such as Washing Machine, Refrigerator etc., 
The facility includes LISN for different purpose such as
  • 50uH/50ohm LISN for civilian standards such as CISPR 11, CISPR 22, FCC Part 15 and CISPR 14-1.LISN
    (Max current : 16A (Single Phase), 32A (per phase for three phase)
  • 5uH/50ohm  LISN’s confirming to CISPR 25, FIAT- 7-Z0472, and FORD ES- X UU7T-1A278-AC standards.
  • 57uH/50ohm LISN supporting current upto 100A used in DC Application.
  • 50uH/50ohm is available current rating upto 200A. 
  • Voltage probe is available for conducted emission measurements for equipments with higher current ratings.

The Harmonic Current Emission facility at SAMEER-CEM as per the International standards IEC 61000-3-2 is capable to measure the current harmonics upto 40th harmonics. The facility supports three phase measurements upto 16A/phase.The facility is fully automated.
