Such identification is not intended to imply recommendation or endorsement by the National Institute of Standards and Technology, nor is it intended to imply that the entities, materials, or equipment(More)
—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 determine the frequency response of high-speed photoreceivers from time-domain measurements collected with a 50 GHz sampling oscilloscope. In order to obtain accurate results, it is important to correct the signals for time-base distortion in the oscilloscope, electrical mismatch, oscilloscope jitter, laser pulse width, oscilloscope frequency response,(More)
We use " standard " optical sources along with microwave calibration methods to accurately calibrate optical receivers to 50 GHz and beyond. The calibrated receivers can be used to characterize sources and receivers using common electrical instrumentation. There are two types of optical sources whose modulation can be measured or calculated from fundamental(More)
