Once the timebase error is known, it can be applied to a simultaneously measured signal of interest if the timing errors of the simultaneous measurements are sufficiently correlated. The software lets users correct random and systematic timebase errors using measurements of two quadrature sinusoids made simultaneously with a waveform of interest.
