摘要： 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.

摘要： A method for generating test data for testing a memory having k data bits and n address bits, where n is less than or equal to 2 times k. For each address location for which test data is desired, the address bits for the location are combined to form the test data for the location. First, two mutually-exclusive groups of n minus k non-repeating bits of the address word are selected. Second, the two groups of address bits are combined using an exclusive-OR operation. Third, the results of the exclusive-OR operation are combined with any remaining bits of the address word to form the test data for the address location. For example, in one embodiment, the most significant n minus k bits of the least significant k bits of the address word are combined, via an exclusive-OR operation, with the most significant n minus k bits of the address word. The resulting data is then concatenated with the remaining bits of the address word.
