Portable E-field strength meter and its traceable calibration up to 1 GHz using a "/spl mu/TEM" cell

The newly developed E-field meter is intended as a transfer instrument between a calibration laboratory and an EMC test facility to measure rf fields that are traceable to national standards. The system is based on a flat miniature E-field sensor and uses software corrections for frequency response, linearity and temperature effects. The calibration procedure with a special "/spl mu/-TEM" cell is described and an uncertainty budget is given.
