2 对称双绞线电缆的现场测试仪器和测量的要求 - 摘要

This Standard includes requirements for field test instruments that are used to test balanced twisted-pair cabling as specified in the ANSI/TIA-568-C series of structured cabling standards. This Standard specifies the reporting and accuracy performance requirements of field testers for balanced twisted-pair cabling measurements. Level IIe, III, and IIIe field tester requirements are specified in this Standard. This Standard contains methods to compare the field instrument measurements against laboratory equipment measurement specified in ANSI/TIA-568-C.2. Measurement accuracy based upon the assumptions for key performance parameters is addressed.
