Impedance Rate Factors: Ka and Kb
Ka or Kb will be used depending on the impedance of the device under test. Only one of these
two factors will be used at a time. Each one has a compensation table that is used to adjust the
result of the calculation based on the length of the cable. The compensation for Ka should be
added to Ka and the compensation for Kb should be multiplied by Kb.
