Fri, 14 Feb 2003 00:56:24 -0400 

Dear all:
Can anyone  kindly let me know how to decide what tests should be performed
for a DC module/product powered by USB port or PS2 port per EMC directive.

My thoughts are listed below:
EN55022 (Conducted Emission--yes; Radiated Emission--yes)
EN 55024
Table 1 -->IEC 61000-4-6--yes, IEC 61000-4-3--yes, IEC 61000-4-2--yes
Table 2 (only for apply to the cable)-->IEC 61000-4-6--yes, IEC61000-4-5--yes,
IEC 61000-4-4--yes
Table 3-no
Table4-no

I am not sure whether my decesions are right or wrong. 
Thanks for your responses in advance!!
