imated model [9] in which rectifier devices are not considered (RI removed and RII short-circuited). This
CC
model uses a Laplace-domain expression to analyse
the response of the electrical driver according to the
parameters of Fig. 1 and certain probe characteristics.
Neglecting ZL ðZL ( RSh Þ and considering the probe
with its cable as a parallel network Rp Cp (only during
this VT calculation phase), a linear expression can be
obtained for VT depending on the amplitude Hv and
switching time s of the step function and the other
parameters detailed in Fig. 1:
