Abstract :
Measurements on a pulse generator have been made at the NRC in Canada and the PTB in Germany. Most of the measured peak values (Vp ) among the laboratories agree to ±0.5%, the front times (T 1) to ±2.0%, and the times to half values (T2 ) to ±1.0%. The differences between calculated calibrator outputs and measured averages were found to be 0.13%, 0.63%, and 0.32% for Vp, T1, and T2, respectively. Contributions of impulse analysis software to the measurement errors are also discussed
