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

The newly developed E-field meter system is intended as a transfer instrument between a calibration laboratory and, for example, an EMC test facility to generate RF fields that are traceable to national standards. The system uses a flat miniature E-field sensor and 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.
