ν
VOP is expressed as a percentage of the speed of light in vacuum.
ν
Pulse is the horizontal (time) width of the pulse for the TDR testing; as the width increases, the maximum measurable distance
increase since the total energy of the pulse is increased. However, the time span corresponding to the pulse width becomes dead
zone within which two adjacent events can be hardly distinguished by the tester.
ν
Average is the degree of average number before which a TDR test result is obtained. The degree is presented in three steps; as the
degree increases, e.g. the average number increases, the noise effect appearing in the plot will be reduced; however, the time for a
test to be completed (or for the waveform display to be refreshed) will be increased.
