Abstract
Improvements to the NPL time domain measurement facility for the calibration of fast oscilloscope risetime are described. Particular emphasis is placed on characterising a coplanar waveguide to coaxial connector transition between a photoconductive pulse generator and the input of an oscilloscope sampling head. Two methods of measuring the transition are described and it is shown that test electrical pulses of less than 4 ps width can be applied to the oscilloscope.
