Fig. 1. A comparison between two methods for evaluating temperature effect on the coaxial cable dielectric length (l_{a probe}): 1) Measuring only the probe's end-point reflection and subsequently correcting for temperature-induced shifts of the probe's length (abscissa) compared to 2) the measurement that subtracts the directly-measured probe beginning from measured end-point reflection (ordinate). The 1:1 line is shown.
