Abstract

The results are presented of an intercomparison of electric field strength generated by calculable dipoles and transverse electromagnetic (TEM) cells from 30 MHz to 100 MHz. An optical electric field sensor (OEFS) is used as the transfer device between an open-area test site (OATS) and two TEM cells. The corresponding calibration factors for the OEFS are measured and compared. The agreement of better than 0.4 dB between the calibration factors obtained in the different facilities gives confidence in the basis of two distinct methods that provide traceability for E-field strength, namely the calculable dipole and the TEM cell.
