An integral part of processing a signal from a calibrated, equivalent-time sampling oscilloscope is accurately determining sampling times and then interpolating the resulting irregularly-spaced time grid to create a uniform time spacing. In this paper, we present simulations and measurements to determine the effect of the interpolation choice on the fidelity of a modulated signal. We judge the effect by calculating the error-vector-magnitude of the resultant signal from each interpolation.
