Page 36: Measuring Interference On Power Lines And Signal Lines With A Current Detection Probe
EMI Receiver Instructions for Use Due to the many measurement errors caused by near-field measurement, how to equate the near-field measurement data to the far-field There is no ready-made theoretical calculation formula. Because the size of the shielded darkroom is different, the electromagnetic wave reflection is different, The test distance is different, so it is difficult to derive a theoretical calculation formula for the equivalent far and near field.
