We have measured the magnitude and phase responses of a photoreceiver to 110 GHz using a calibrated electro-optic sampling system. The frequency range of the calibration is limited only by our 1 mm coaxial connectors. In this paper, we present a method for accurately characterizing the response of a commercially available photoreceiver to 110 GHz, nearly… (More)
—In this paper, a method of correcting both random and systematic timebase errors using measurements of only two quadrature sinusoids made simultaneously with a waveform of interest is described. The authors estimate the fundamental limits to the procedure due to additive noise and sampler jitter and demonstrate the procedure with some actual measurements.
—We describe a method for calibrating the voltage that a step-like pulse generator produces at a load at every time point in the measured waveform. The calibration includes an equivalent-circuit model of the generator that can be used to determine how the generator behaves when it is connected to arbitrary loads. The generator is calibrated with an… (More)
—We present a procedure for correcting the timebase distortion (TBD) and jitter of temporal waveforms of arbitrary lengths. This is achieved by estimating the TBD and jitter sequentially with overlapping measurements and using the information in the overlapping portion to adjust the results. We use eye diagrams to demonstrate the effectiveness of the… (More)
—We describe a stable method for calibrating digital waveforms and eye diagrams by use of the measurement system response function and its regularized inverse. The function describing the system response includes the response of the oscilloscope and any associated cables and test fixtures. We demonstrate the effectiveness of the method by performing a… (More)
