SYS-400 is a general
pourpose crate that can host up to 20 4TE 3U Eurocard boards.
The SYS-400, can host up to 8 high voltage square wave pulsers
( mod. PX-400 ), up to 8 high gain receivers ( mod. RX-400 ) and
one controller ( mod. PC-20, mod. PC-100, mod. PC-S, mod. CPU-400
) to build up a very powerful ultrasonic instrument. Its
also possible to use only one pulser and one receiver. In any
moment the custumer could upgrade the system by adding other pulser

foreseen to display/acquire the right channel. Three different
types of controller has been designed to tailor the SYS-400 to
the customers needs.
