Short summary
A near-field measurement based pre-compliance method is provided for predicting emission below 30 MHz in a CISPR-25 test set-up. The Huygens principle by defining an unclosed Huygens' surface is applied for field prediction. Near-field measurements are only conducted for several locations over a table surface and a static electric field formula is used for field distribution estimation. The difference of the predicted E-field at 1 m distance is within 4 dB compared with full-wave simulation.
