Laser Powered Probe – RadiSense® 10 E-Field sensor for radiated immunity EMC testing. Due to a new patented technology, dramatically improving the isotropic behaviour, the RadiSense 10 is the most accurate electrical field (E-Field) probe in the world! The probe can be used to measure the field strength over a wide frequency band of 9 kHz to 12 GHz. The ongoing endeavour of DARE!! Instruments to develop better products, has now resulted in an unprecedented accurate E-Field probe. Why is accuracy important? In order to perform accurate EMC immunity (susceptibility) testing, the absolute electrical field strength has to be determined. This is the case during the actual testing, as well as during verification for substitution testing and the 1-, 4- or 16-point calibrations. Based on these results, the power to be provided by the signal generators and power amplifiers is determined. Hence the accurate measurement of the electrical field is of the utmost importance to perform realistic immunity tests. Therefore, probe manufacturers have made great efforts to improve the accuracy of E-Field probes. What influences accuracy? First of all, the size and shape of the probe itself are important factors. The smaller the probe the better. The invention of the laser powered E-field probe by DARE!! Instruments in 1999 was an important step in this respect. Secondly the move to spherical probes instead of square probes improved the accuracy. Furthermore, amplitude linearity, frequency response, temperature drift and the often forgotten non-isotropic behaviour of the probe, are important parameters.
