An international intercomparison of horn gain and polarization measurements at X-band has recently been completed. There were seven participating laboratories with the National Institute of Standards and Technology serving as the pilot laboratory. Two X-band pyramidal standard gain horns with a nominal gain of 22 dB served as the traveling standards. Quantities measured included on-axis fixed frequency gain at 8, 10, and 12 GHz, swept frequency gain between 8-12 GHz and polarization characteristics at the three fixed frequencies. All laboratories performed the fixed frequency-gain measurements. The swept-frequency and polarization measurements were optional, with four laboratories performing swept-frequency measurements and three laboratories measuring polarization. The results of the gain measurements generally agreed within the reported uncertainties which were of the order of 0.1 dB or less.

Abstract-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).

We report the results of an international comparison of measurements of radio frequency voltage in the frequency range 1 MHz to 1 GHz. This comparison was performed as a Key Comparison under the auspices of the Consultative Committee for Electricity and Magnetism (CCEM) of the International Committee for Weights and Measures (CIPM). Participating laboratories were the designated national metrology institutes (NMIs) for their respective countries.Main text. To reach the main text of this paper, click on Final Report.
