Calibration of RF field strength meters

摘要

An intercomparison of field strength meters was performed during 1991-1993 over the frequency range 100 kHz-1000 MHz and field strength range 1-10 V/m using different calibration techniques. Four field sensors, electric as well as magnetic, have been used. Seven institutes participated in this intercomparison using at least three different calibration methods. A calibration uncertainty of less than 1 dB can be obtained if certain procedures are followed. The results are applicable in the fields of EMC testing and health care (nonionizing radiation).
