Conducted Disturbance Test


Conducted disturbance test mainly tests the interference intensity caused by the voltage and current of electronic and electrical equipment or system to other equipment when it is transmitted through the signal line, power line or ground wire during normal operation, and tests whether these disturbances exceed the limit value required by the standard. Similar to the radiated emission, the test measured value is compared with the limit to determine whether the EUT (equipment under test) is qualified, and if the measured value is lower than the limit, it will pass, otherwise it will fail, so as to ensure that other equipment working on the public grid is not interfered.

Conducted Disturbance Test Technology

When the EUT current is too large or the LISN cannot be used for measurement, such as the EUT control port, a high impedance voltage probe can be used to cooperate with the receiver for measurement.

detection technology

The shielding room of Tianhai detection is designed based on the modular structure system.

The use of R & S as well as Schwarzbeck imported test equipment, prefabricated high-quality shielding plates ensure great flexibility to meet various possible sizes. All flat panel modules allow easy operation and access through standard building doors. Fix the standard module from the inside with bolts every 75mm, and insert a highly conductive mesh gasket to seal the connection of the panel. This facilitates installation near the walls of the main building. Small pitch, screw torque precision, with rated torque, to ensure long life shielding attenuation characteristics.

Tianhai Testing Laboratory


Tianhai testing is set up and operated in accordance with the laboratory accreditation system specification ISO 17025. The testing instruments are made up of Germany's Rohde & Schwarz, Switzerland's EMTEST, YYOKOGAWA, Agilent, Tektronix and other world's top instrument manufacturers. The equipment is advanced and sophisticated, the site environment control is reliable, traceability is strong, the technical team is senior and efficient, and close cooperation with international authoritative organizations is maintained.
