Radiation immunity testing measures using electric field probes

[Application Example] Introduction of the EMS (Immunity) Pre-evaluation System

Instead of bringing the equipment under test (EUT) to the EMC test site and conducting immunity tests multiple times, a simplified interference wave test can be performed. By operating a dedicated program, the electric field strength of the radiated interference wave is set. Following the GUI screen instructions, the electric field probe measures the target area (up to 4 locations). To enhance test accuracy, calibration data with high degrees of freedom is automatically created by changing the position of the probe. 【Solution】 An electric field probe is installed on the EUT setup stage inside the anechoic chamber. Calibration data is automatically generated by the test software according to the size of the EUT. (1) The electric field probe is placed at any position on the stage. (2) Align with the EUT surface facing the antenna and measure the electric field strength (up to 4 locations). (3) Record calibration data for each position according to the target frequency range. (4) Incorporate the calibration data into the test software and start the EMS pre-test. *For more details, please refer to the PDF document or feel free to contact us.
