CISPR16-1-4 Tricyclic Radiation Magnetic Field Induced Current Test System for Luminaries

Standards & Clauses:

CISPR15/ GB17743: Limits and methods of measurement of radio disturbance characteristics of electrical lighting and similar equipment

CISPR16-1-4: Radio disturbance and immunity measuring apparatus –Ancillary equipment –Radiated disturbances Reference

Samples and Restrictions:

Luminaries and other devices

Application:

For lighting and other devices that may produce low-frequency magnetic field, the loop antenna system required by the CISPR16-1-4 standard shall be used to measure the low-frequency magnetic field radiation harassment.

Test Principle:

The measured object (EUT) is placed in the middle of the three-loop antenna. The three-loop antenna converts the low frequency magnetic field components in the X direction, the Y direction and the Z direction into an RF signal and switches the three channels through the coaxial switch to the EMI receiver measuring. The test should be conducted in a shielded room.

Structure:

Main test equipment: receivers, three-loop antenna, EMC test software
Test environment: shielded room (height greater than 3.3m)

Use Environment​:

Power supply: 380V ± 10%, 50 / 60Hz
Ambient temperature: 5 °C ~ +40 °C, there should be no high concentration of dust, corrosive gas, flammable and explosive objects

Technical Parameters:

Main Test Equipment	Receivers, three-loop antenna, power absorbing clamp, decoupling clamp, slide rail, EMC test software, etc.
Test Environment	Shielded room (height greater than 3.3m)
