Notes:
The configurations with one channel are obtained taking into consideration the S11/
S12 input only. In this case it is necessary to consider time tR1 referred to input
S11/S12, time tR referred to the supply, time tA referred to input S11/S12 and to the
start, and time t

referred to the start.
