The commands are numerically coded on a dSpace fast
prototyping development system: 40μs /16 bits ADC
(Analog to Digital Converter) for pressure acquisitions,
16 bits/±10V DAC (Digital to Analog Converter) for
command of the servo-valve through a linear power amplifier
(providing a regulated current from 0 to 400mA
from a +/- 10V DAC command).
