Data record `instr.time-domain-reflectometer.velocity-factor`

Verified 2026-10-27 Confidence: High

The distance scale depends on the velocity factor (velocity of propagation) set on the instrument for the cable under test, and handheld instruments allow the factor to be set over a wide range so that any cable construction can be measured; the maximum range likewise depends on the factor selected and the cable type.
