Measurement points are given in Table 10.

Definitions for test circuit:

RL = Load resistance.

CL = Load capacitance including jig and probe capacitance.

RT = Termination resistance should be equal to output impedance Zo of the pulse generator.

VEXT = External voltage for measuring switching times.
