The test systems of 4G-TeSys family make testing very easy, by quickly configuring test plans and executing tests, in support of validation process, and reporting test results.

The systems are based on the reference 4G-TeSys configuration depicted hereafter.


4G-TeSys is constituted with the following elements:

  • A Personal Computer, to program the test and process the results
  • The 4GTestStudio suite, which contains the software tools to program the tests, define the results processing and the desired reports, and to generate the necessary codes to run the "testing machine"
  • A "testing machine" to stimulate and to collect data, realized with National CompactRIO or PXI
  • An Hardware Interface Module, which shall be custom designed, to adapt SUT (System Under Test) input/soutputs for signal conditioning and power driving.

CompactRIO™ and PXI™ are registered trademarks of National Instruments.

4G-TeSys configurations

Three different configurations enable fitting with almost all test requirements, both on-bench and on-vehicle (see the following table and the specific features of the systems).
