Repeatability is used to determine the length of the test observation period. There is NO need to repeat measurements. There may be a proposal to clarify this officially. > >Also in Table Z1 (clause 6.2.4, page 14), what is the type of equipment >behavior called out as "quasi-stationary"? > Equipment whose harmonic emissions vary with time only to an insignificant extent. The 'quasi-' recognizes that it is very unlikely that there would be absolutely no variation with time. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?
