COMMENTS: System continuously running with XBB Demo program as observed on the host PC monitor. 
Ambient temperature 61°F and relative humidity of 63%. The ambient temperature of the actual EUT was 
within the range of 10

 to 40

 C (50

 to 104

 F) unless the particular equipment requirements specify testing 

over a different temperature range. The humidity levels were within the range of 10% to 90% relative humidity 
unless the EUT operating requirements call for a different level. Emissions above 1 GHz are maximized 
measurements with peak detector at 3 meter test distance.
