RE Limit

The RE Limit module provides a means by which to compare calculated radiated emissions levels to a radiated emissions limit.  A limit is defined by entering frequency/amplitude pairs in tabular format.  A graph of the limit is generated automatically.  At the completion of a RE analysis this graph can be overlaid on the radiated emissions graph for comparison. 

Radiated emissions limits are specified by regulatory agencies, e.g. the FCC in the United States or CENELEC for the European Union, or by the procuring agency in the case of military equipment.  Refer to applicable radiated emissions requirements for your equipment to determine the frequency/amplitude values to enter.

The limit is not used in the calculation of radiated emissions.  It is only used for comparison to calculated values at the completion of a RE analysis.  It is not necessary to define a limit in order to perform a RE analysis.  Once the limit information has been entered the status bar beneath the Filter button on the RE Analyst form is changed from red to green.
