Maximum Radiated Emissions Calculator (MR EMC)

The Maximum Radiated Emissions Calculator determines the maximum possible radiated emissions from various printed circuit board structures. In addition to calculating the radiated emissions directly from the circuit board, it can also calculate the maximum possible radiated emissions from cables and structures connected to the board even when the size and orientation of those structures has not been specified.

The calculator works based on the assumption that everything that is unknown is worst case. For example if you know that there are cables attached to your board, but you don't specify their size or geometry, the calculator assumes that they are resonant at every frequency.

The calculator evaluates different types of radiation using separate algorithms. Therefore, if you want to know the maximum amount of radiated emissions due to noise on a microstrip trace being radiated directly from the circuit board, you would choose the differential-mode EMI calculator. If you want to know the maximum amount of radiated emissions due to noise on a microstrip trace being radiated by the cables attached to the circuit board, you would choose the common-mode EMI calculator.
