Calibration and use of EMC antennas.
Author: Alexander, M J
Source: Measurement Good Practice Guide No. 4 ,April 1997.
Abstract: The documentation addresses the calibration of electromagnetic compatibility (EMC) antennas in the frequency range 30 Hz to 40GHz. Guidance is given on the assessment of uncertainties in their use for EMC radiated emission measurement.
The use of GTEM cells for EMC measurements.
Author: Nothofer, A, Alexander, M J, Bozec, D*, Marvin, A*, McCormack, L*
Source: Measurement Good Practice Guide No. 65 ,January 2003.
Abstract: This guide is aimed at users of GTEM cells. Its purpose is to help them achieve good practice in EMC emission and immunity tests with their GTEM cell. Reference is made to the IEC standard 61000-4-20 on the EMC uses of GTEM cells.
Good practice guide to phase noise measurement.
Author: Owen, D*
Source: Measurement Good Practice Guide No. 68 ,May 2004.
Abstract: Measurement of phase noise has become important in designing and developing systems for communications which pervade so much of our daily life. Without good, low phase noise oscillators in systems such as mobile telephone systems, the levels of interference experienced by users would become unacceptable. Improvements in these systems are often contingent upon improved oscillators and these improvements can only be quantified through good measurements of phase noise.

Abstract: This document addresses the calibration of antennas in the frequency range 30 Hz to 40 GHz. Guidance is given on the assessment of uncertainties in their use for radiated emission measurements according to EMC standards. The National Physical Laboratory operates calibration services for the measurement of antennas factors of monopole, loop, dipole, biconical, log-periodic and horn antennas which are used for emission testing on open area test sites and in fully anechoic chambers. Most of the calibration methods and the advise given applies to the use of antennas in other applications.
