چکیده

Electromagnetic compatibility (EMC) compliance testing for the CE-certification of electronic apparatus involves the measurement of radiated-emissions in the frequency range of 30 MHz to 1 GHz. To achieve equivalent test results from different testing laboratories, test sites must be of validated, standard performance. This paper suggests two substantial improvements to the standard site validation procedure: (i) Precise, numerically calculated reference values of site attenuation for tuned dipoles are given. (ii) The new "site-reference method" for site validation is suggested. It avoids the determination of the antenna factors of transmit and receive antenna and minimizes uncertainties in the measurement result. This improves the reliability of judgements upon site performance and helps to economize the design of test facilities, e. g. anechoic chambers. Übersicht Überprüfungen der elektromagnetischen Verträglichkeit (EMV) zur CE-Zertifizierung elektronischer Geräte beinhalten Störfeldstärkemessungen im Frequenzbereich von 30 MHz bis 1 GHz. Um von verschiedenen Prüflaboratorien gleichwertige Testergebnisse zu erhalten, benötigt man normgerechte, überprüfte Meßstrecken. Diese Arbeit schlägt zwei substantielle Verbesserungen des genormten Validierungsverfahrens für Meßstrecken vor: (i) Präzise, numerisch berechnete Referenzwerte der Felddämpfung für abgestimmte Halbwellendipole; (ii) Die neue "Referenzgelände-Methode" zur Meßgeländeüberprüfung. Diese vermeidet die Bestimmung der Antennenfaktoren von Sendeund Empfangsantenne und minimiert die Unsicherheiten im Meßergebnis. Das erhöht die Zuverlässigkeit bei der Beurteilung der Eignung eines Meßgeländes und gestattet ein wirtschaftlicheres Design von Meßeinrichtungen wie z. B. Absorberhallen. Für die Dokumentation Absorberhalle, echoarmer Raum, elektromagnetische Verträglichkeit, EMV, Störfeldstärkemessung, Felddämpfung, Freifeld-Meßgelände, Referenzgelände.

Emc 2002 International Wrocław Symposium and Exhibition on Electromagnetic Compatibility Validation of Semi-anechoic Chambers with Tuned Halfwave-dipoles Working over a Wide Frequency Band

In this paper the latest techniques for validation of anechoic chambers are described. The Short Dipole Site Validation Method (SDSV) is based on the use of the CISPR 16 dipole in an expanded, non-resonant frequency range. The SDSV idea is great as it combines advantages of the Site Reference method (direct comparison of two site attenuations, no antenna factors involved, quasi-swept frequency ...

Comparison of Single- site and Multi-site Based Calibrations of SWAT in Taleghan Watershed, Iran

Calibration of model is critical for hydrologic modeling of large watersheds in a mountain watershed. In this study Soil and Water Assessment Tool (SWAT) used to comparison a single-site calibration procedure that employed streamflow measurement at outlet of watershed to a multi-site calibration method that used streamflow measurements at three stations (Galinak, Joestan and Dehdar). Results sh...

Vicarious calibration of CCD camera on CBERS02B using Gongger test site

on September 19 2007, CBERS02B, the third land resource satellite jointly developed by China and Brazil was successfully launched with three payloads on it, one of which is CCD camera. Calibration of CCD is a precursor for its quantitative application because there wasn’t onboard calibrator for CCD. Then a comprehensive vicarious calibration and validation experiment of CCD was performed at Gon...
