Pulse Transition Duration Measurements and Standards at NIST -- 1975 to 1988



W L. Gans, N. S. Nahman, J R. Andrews, E E. Baldwin


The techniques employed by NBS from the mid 70s through 1988 for the calibration of the pulse transition duration (TD) of a fast, step-like, electrical pulse generator are described along with the artifact requirements imposed on the pulse generator. The fundamental definitions and measurement and generation methods relevant to the calibration of pulse transition duration are presented. Subjects discussed include the IEEE Pulse Standards 181-77 and 194-77, deconvolution as applied in (1) time-domain waveform measurements of a pulse and in (2) network impulse response characterization, and the NBS 50ps, 100ps, and 200 ps Transition Duration Transfer Standards which are based upon a tunnel diode step-like generator (TD about 20 ps), and Debye liquid-dielectric coaxial line filters. The Appendices contain electronic circuit diagrams and mechanical drawings for the transition Duration Transfer Standards.
