This test bombards the EUT with electric fields that may couple into the system via chassis slots and interface 

cables and evaluates the product’s immunity.  Testing was performed in accordance with IEC 61000-4-3.  The 

RF immunity test entails subjecting the equipment under test to a uniform field of radiated electromagnetic 

energy of a specified field strength and frequency, and monitoring the functionality of the device as the 

frequency is swept over a specified frequency range.   

 

The EUT is set up inside a shielded, semi-anechoic chamber with a radiating antenna at a distance of 3 meters 

from the EUT.  For further information, please refer to the technical sections in the IEC 61000-4-3 publication in 

addition to the test results section and photographs of the test set-up provided in this report.

This test injects a transient/burst interference onto the AC/DC power supply and signal I/O lines.  Testing was 

performed in accordance with IEC 61000-4-4.  The standard configuration for “type tests” outlined in IEC 61000-

4-4 is used.  For further information, please refer to the technical sections in the IEC 61000-4-4 in addition to the 

test results section and photographs of the test set-up provided in this report.
