Nose-to-Nose Oscilloscope Calibration Phase Error Inherent in the Sampling Circuitry
Catherine A. Remley
We use simulations to study the dependence of the phase error in the nose-to-nose oscilloscope calibration on the oscilloscope's sampling circuitry. We determine which components of the internal sampling circuitry of the oscilloscope contribute most significantly to errors in the nose-to-nose calibration. We then predict an expected range of phase errors from a range of realistic component values.
