Final report on key comparison CCEM.RF-K24.F: E-field measurements at frequencies of 1 GHz, 2.45 GHz, 10 GHz and 18 GHz and at indicated field levels of 10 V/m, 30 V/m and 100 V/m

Abstract

A comparison of electric field measurements was carried out between January 2010 and July 2012 amongst fourteen national metrology laboratories at frequencies 1 GHz, 2.45 GHz, 10 GHz and 18 GHz at indicated field levels of 10 V/m, 30 V/m and 100 V/m. The identification of this intercomparison is CCEM.RF-K24.F. Two electric field probes provided by Amplifier Research have been measured as the travelling standards. The National Physical Laboratory (United Kingdom) acted as the pilot laboratory for the comparison. This report contains the results of the measurements.Main text.

Results of an intercomparison for electric field strength measurements within the German calibration service

“…The outcome of this comparison was one of the triggers for re-establishing the standardization working group DKE GAK 767.4.3 "Feldsondenkalibrierung" which works on a first draft on a new standard IEC 61000-4-26 "Field Probe Calibration". The goal of this working group is to overcome the shortcomings identified in current standards and technical guidelines such as IEEE Std 1309 TM -2013(IEEE 1309, 2013), IEC 61000-4-3:2006(IEC 61000-4-3, 2006 and VDI/VDE/DGQ/DKD 2622 Blatt 10 (VDI/VDE/DGQ/DKD 2622, 2004) by targeting all aspects of field probe calibration required for accurate measurements, including field generators, calibration process and the application of the field probe.…”
