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.0@ ANSI/TIA-568-C.2 and ANSI/TIA-568- C.2-1 structured cabling standards. This Standard specifies the reporting and accuracy performance requirements of field testers for balanced twisted-pair cabling measurements. Level IIe@ III@ IIIe and 2G 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 for category 6A and below@ and ANSI/TIA-568-C.2-1 for category 8. Measurement accuracy based upon the specifications or assumptions for key performance parameters is addressed.
