HDTDX Analyzer Specifications for Cables <100 m
(328 ft)
The specifications below are typical for cables less than
100 m (328 ft).
HDTDR Analyzer Specifications for Cables <100 m
(328 ft)
The specifications below are for HDTDR tests on cables less
than 100 m (328 ft) long.
Characteristic Impedance
The tester reports an estimate of the cable's impedance at
4 m from the beginning of the link. The accuracy of the
measurement is relative to a 100
Ω
terminating resistance.
Impulse Noise
Adjustable from 10 mV to 500 mV in 10 mV steps.
Monitors either polarity of noise on pair 3, 6.
Minimum detectable impulse width: 10 ns
