Abstract
In this erratum we correct errors in the scaling and caption of Fig. 4 in the original manuscript [1].

An error in the scaling of the phases plotted in Fig. 4 of the manuscript [1] was found after publication. The revised figure is shown below as Fig. 1 of this erratum. Furthermore, the line colors and the description in the figure caption are changed in order to coincide with the respective line colors in Fig. 3 of [1], as initially intended. These corrections have no effect on the results and the conclusion of the paper.
Fig. 1. Temporal phase evolution $\varphi _{\mathrm {DUT-ref}}(t)$ scaled to an optical carrier frequency of 194.4 THz during time intervals with continuous data. The CP (orange, left scale) and NCP (blue, right scale) measurements were not performed simultaneously.
