  30 Nanosecond Settling Time Measurement for a Precision Wideband Amplifier &mdash AN79
  PDF, 624 Kb, File published: Sep 5, 1999
  AN79 modifies methods presented in AN74, permitting verification of 30 nanosecond amplifier settling times to 0.1% resolution. The sampling-based technique used is detailed and results presented. Appendices cover oscilloscope overdrive issues, construction of a subnanosecond rise time pulse generator, amplifier compensation, circuit construction and calibration procedures.

  30 Nanosecond Settling Time Measurement for a
  Precision Wideband Amplifier
  Quantifying Prompt Certainty
  Jim Williams Introduction
  Instrumentation, waveform generation, data acquisition,
  feedback control systems and other application areas
  utilize wideband amplifiers. New components (see page 2
  “A Precision Wideband Dual Amplifier with 30ns Settling
  Time”) have introduced precision while maintaining high
  speed operation. The amplifier’s DC and AC specifications
  approach or equal previous devices at significantly lower
  cost while saving power.
  Settling Time Defined
  Amplifier DC specifications are relatively easy to verify.
  Measurement techniques are well understood, albeit often
  tedious. AC specifications require more sophisticated
  approaches to produce reliable information. In particular,
  amplifier settling time is extraordinarily difficult to determine. Settling time is the elapsed time from input application until the output arrives at and remains within a
  specified error band around the final value. It is usually
  specified for a full-scale transition. Figure 1 shows that
  settling time has three distinct components. The delay …
