Analyzer Specifications for Cables <100 m (328 ft)
The following performance is typical for cables less than 100 m (328 ft):
Distance accuracy: ±(1 ft (0.3 m) + 2 % distance)
Distance resolution: 1 ft or 0.1 m

Impulse Noise
Adjustable from 10 mV to 500 mV in 10 mV steps. The default threshold is
270 mV.
Monitors either polarity of noise on pair 3, 6.
Minimum detectable impulse width: 10 ns
Characteristic Impedance
The test tool 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.
