AN INTERPOLATION METHOD TO CALIBRATE ELECTROMAGNETIC PROBES IN SEMI-ANECHOIC CHAMBERS

An Interpolation Method to Calibrate Elec- Tromagnetic Probes in Semi-anechoic Cham- Bers

Based upon the standard IEEE 1309, a new calibration method for electromagnetic (EM) probes is proposed. The aforementioned method compares the electric field strength measured with the EM probe subject to calibration with the E-field intensity calculated through a linear interpolation of the corrected measurement using a reference EM probe. The corrected measurement results are computed by mea...

Anechoic vs. Semi Anechoic Rooms

Minimum Usage of Ferrite Tiles in Anechoic Chambers

Anechoic chambers which are used for emission and immunity testing require expensive ferrite tiles on their inner surfaces. This paper describes a method to reduce the number of required ferrite tiles, whilst ensuring a reliable and specified test region. In this method, the positions of some ferrite tiles are found optimally to keep the performance of the anechoic chamber as high as possible. ...

Emc 2002 International Wrocław Symposium and Exhibition on Electromagnetic Compatibility Validation of Semi-anechoic Chambers with Tuned Halfwave-dipoles Working over a Wide Frequency Band

In this paper the latest techniques for validation of anechoic chambers are described. The Short Dipole Site Validation Method (SDSV) is based on the use of the CISPR 16 dipole in an expanded, non-resonant frequency range. The SDSV idea is great as it combines advantages of the Site Reference method (direct comparison of two site attenuations, no antenna factors involved, quasi-swept frequency ...

A Method to Calibrate the Electromagnetic Tracking Instrument When Measuring Branches of Fruit Trees

To reduce the effect from instrument error when getting characteristic parameters of branches of fruit trees by the electromagnetic tracking instrument, a calibration method was sounded based on a discussion of the instrument error of electromagnetic tracking instrument. Finally, the method was tested in an experiment. By comparing the data of the experiment and the standard data which was got ...
