4.1.2 TEST PROCEDURE
a.
The EUT was placed 0.8 meters from the horizontal ground plane with EUT being connected to the
power mains through a line impedance stabilization network (LISN). All other support equipments
powered from additional LISN(s). The LISN provide 50 Ohm/ 50uH of coupling impedance for the
measuring instrument.
b.
Interconnecting cables that hang closer than 40 cm to the ground plane shall be folded back
and forth in the center forming a bundle 30 to 40 cm long.
c.
I/O cables that are not connected to a peripheral shall be bundled in the center. The end of the
cable may be terminated, if required, using the correct terminating impedance. The overall
length shall not exceed 1 m.
d.
LISN at least 80 cm from nearest part of EUT chassis.
e.
For the actual test configuration, please refer to the related Item –EUT Test Photos.
