To investigate the maximum EMI emission characteristics generates from EUT, the 
test system was pre-scanning tested base on the consideration of following EUT 
operation mode or test configuration mode which possible have effect on EMI 
emission level. Each of these EUT operation mode(s) or test configuration mode(s) 
mentioned above was evaluated respectively.
