適用范圍：This document reports the measurement results of a round robin test program carried out on SC/APC plugstyle fixed attenuators. The work was initiated at CENELEC CLC/TC 86BXA in November 2004 in order toget a clear understanding on the accuracy and repeatability of the spectral attenuation loss measurements onfixed attenuators.Out of these results some recommendations are made for attenuation tolerance values that can be used inthe performance standards.
