System for functional and parametrical test of ignition systems for gas turbine engines.
Functional testing (FCT) is typically performed during the last phase of the production process. This is often referred to as a final quality control test, which is done to ensure that specifications for the DUT (Device under test) are met.
During the test sequence you normally apply a parametrical analysis, and the data is often collected and stored for product yield, traceability etc..
The process of FCTs is entailed by the emulation or simulation of the environment in which a product is expected to operate. This is done to check, and correct any issues with functionality. The environment involved with FCTs consists of any device that communicates with the DUT including the power supply and loads that are needed to make the DUT function correctly.
