ABSTRACT:
A system and method for assessing the electric and magnetic field generated by equipment under test (EUT) by maintaining the EUT in a specified, fixed tilt position, allowing the EUT to rotate while in that specified position and tilting the TEM cell through at least two angles about the EUT. Embodiments contemplate that a fixed tilt mechanism for maintaining the EUT in a fixed position relative to the tilting of the TEM cell is used. The present invention further contemplates various schemes for determining the electric and magnetic fields generated from the EUT based upon the composite electromagnetic reading from the TEM cell. These schemes, which result in improved measurements of the magnetic and electric fields, determine the angles to which the TEM is tilted.
