Some Basic Considerations Concerning Time-Domain Measurements withElectromagnetic-Field Sensors (Enkele Aspecten Aangaande Tijddomein Metingen met Elektromagnetische Veldsensoren)

摘要

This report presents some ideas concerning time-domain measurements withelectromagnetic-field sensors, and how the time-domain measurements can be performed. A very simple method is enunciated to correct the influence of the low cut-off frequency of the sensor. It is shown that the low cut-off frequency of the sensor can be found from its time-domain response to a NEMP. The practical value of this method is demonstrated by experiments. Finally, time-domain calibration of electromagnetic field sensors is addressed. Especially, the influence of the bandwidth of the measuring system is investigated. It is found that the influence of the bandwidth can be compensated.
