Cable Type Specification
Unshielded Twisted Pair LAN cables (100 and 120 Ohm UTP category 3, 4, 5, 5E,
and 6 ISO/IEC Class C and D)
Foil-screened Twisted Pair cables (100 and 120 Ohm ScTP category 3, 4, 5, and 6
ISO/IEC Class C and D)
Cable Length
Open or shorted
Terminated with
greater than or equal to
15% reflection
Length accuracy is dependent upon the cable type selected in the
Cable Test | Twisted-Pair Detail screen with its ideal NVP (nominal
velocity of propagation) matching the NVP of the cable under test.
Characteristic Impedance:
50 to 150 Ohms, cables 3-5 m (10-16 ft.) +/- (5 Ohms +10%)
50 to 150 Ohms, cables >5 m (16 ft.)
Resolution: 1 Ohm
