Projects

Test systems

We have produced several test systems equipped with software and automatic test procedures.

All the HW and SW laboratories collaborated in the development of the systems:
. System engineering (design analysis, functional high-level specifications)
. SW lab (SW Design and implementation, based on Customer frameworks)
. HW lab (Design, implementation and electrical and functional tests on various HW units)
. FPGA lab (Design, implementation and testing of FPGAs for functional test units)
. Physical design (Design of internal and external cables, design of 19'' metal boxes for HW development boards)
. Office design (Coding and verification of production documentation)

In addition, the following activities were carried out:
· TE internal wiring
· Acceptance and stand-alone verification of TEs
using self-check and self-test systems
· Certification CE

Electrical test systems

Each test system is equipped with a suitable junction box.
Each junction box has a connection interface between the DUT
and the internal measuring instruments.

With junction boxes it is possible to:
· Interface with a 400 + 400 x 2 interconnect matrix
(developed on the basis of National Instruments systems board);
· Connect the correct load to the device under test
· Connect each single signal of the external harness to measuring instruments installed in the TE, in order to perform electrical tests.

All junction boxes mount the same type of PCB boards that make an interconnect between the DUT and the TE, thus improving reusability in various different designs.

We have also developed different PCB boards for specific requirements of each TE regarding electrical tests;
So that many cards developed in the past can be used in various fields
without substantial modifications

Automatic control unit

Most of the TEs developed and produced are equipped with an automatic control unit, programmed to check the entire TE without the presence of the DUT, using only the external wiring cables equipped with the TE itself.
Using this unit allows an accurate verification of the TE, highlighting possible errors in wiring and/or in general the installed instruments.

This unit is located on the back of the TE and is managed by its own SW that can be used by any operator, with the help of simple guided procedures to perform all possible tests.
