Performance Specifications Note: all specifications for tests on twisted-pair cabling apply to 100 Ω cable. Contact Fluke Networks for information on measurement performance for cable with a different impedance.
Baseline accuracy The baseline accuracy of all DTX Series testers meets or exceeds the requirements of Level IV as in draft 2nd Edition of IEC 61935-1 over the frequency range supported by the tester.
Category 6/Class E link test modes (and lower link categories) DTX CableAnalyzer far exceeds Level III requirements of TIA/EIA-568-B.2-2 and IEC 61935-1
Class F link test modes DTX-1800 is compliant with Level IV requirements as in the draft 2nd edition of IEC 61935-1.
