On the other hand, test systems for use in aerospace & defense (A&D) applications can have a typical lifespan of 25 years or even more. If standard measuring instruments with a lifespan that is significantly less than this time frame are used in such test systems, an obvious question is how to handle maintenance, repair, calibration and even replacement of the instruments that are no longer supported by their manufacturer. Moreover, the test program sets (TPS) used in such test systems are generally certified, which makes it very time-consuming and costly to modify and reaccept them.
The webinar describes the aspects that must be taken into account when instruments are to be designed so that they can serve as drop-in replacements for obsolete older instrumentation.
