This test simulates electrostatic events (similar to being “zapped” by touching a light switch) and evaluates the 
ability of the EUT to tolerate such events.  Testing was performed in accordance with IEC 61000-4-2.  
Tabletop devices are placed on an insulated mat on a horizontal coupling plane.  Air discharges and contact 
charges are made to the EUT on connectors and conducting surfaces (as illustrated in the Test Results section 
of this Test Report).  The discharges shall be applied in two ways: 

a)  Contact Discharges to the conductive surfaces and to coupling planes: 
The EUT shall be exposed to at least 200 discharges, 100 each at negative and positive polarity, at a 
minimum of four test pints (a minimum of 50 discharges at each point).  One of the test points shall be 
subjected to at least 50 indirect discharges (contact) to the center of the front edge of the horizontal-
coupling plane.  The remaining three test points shall each receive at least 50 direct contact discharges.  If 
no direct contact test points are available, then at least 200 indirect discharges shall be applied in the 
indirect mode.   

b)  Air Discharge at slots and apertures, and insulating surfaces: 
On those parts of the EUT where it is not possible to perform contact discharge testing, the equipment 
should be investigated to identify user accessible points where breakdown may occur.  This investigation 
should be restricted to those areas normally handled by the user.  A minimum of 10 single air discharges 
of each polarity and test level shall be applied to the selected test point for each area.   
 

For further information, please refer to the technical sections in the IEC 61000-4-2 publication in addition to 
the test results section and photographs of the test set-up provided in this report.

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.
