The effects of offset voltage on the amplitude and bandwidth of kick-out pulses used in the nose-to-nose sampler impulse response characterization method

The amplitude and bandwidth of kick-out pulses used in the nose-to-nose sam pler impulse response characterization method were measured as a function o f offset voltage. The measuring instrument was of similar bandwidth and its effects on the measurement were not removed. The amplitude is almost linea r for offset voltages from -500 mV to 500 mV, except for values from about -50 mV to 50 mV. Slight changes in bandwidth were observed for offset volta ges from -250 mV to 250 mV with significant bandwidth loss observed for off set voltages outside this range.
