Module MVVDSU

mvvdsu

For outputting of determined with the characteristics sequence of control actions on the unit under test when aligning with certain characteristics signaling information from the unit under test entering the modules. It’s used as a part of orbital vehicles computer-aided testing and controlling system. Settled into "Evromechanika " type block case. Preparation is made in the following way: signaling information codes list module and corresponding to them codes sequences lists of control actions delayed. Information enters module through KVV-S controller under the set command from PC.
