Time-Domain Calibrations of D-Dot Sensors



Robert T. Johnk, Arthur Ondrejka


This Tech Note covers in detail the procedures that are necessary to measure the receive transfer function of a broadband electric-field sensor using direct-pulse, time-domain methods. The calibration techniques presented here are applicable to a cone and ground plane system in the 50 MHZ to 14 GHz frequency range, as well as to TEM cells in the 10 MHZ to 100 MHZ range. Measurement results that were obtained using both types of facilities are presented for a selected D-Dot sensor. In addition to a comparison of results from the two measurement facilities in the overlapping frequency ranges, a thorough combined uncertainty analysis (Type-A and Type-B) uncertainties are presented.
