Validation of the design is a milestone in development cycle of a system. Actual testing of the component is an ultimate means to carry out the design validation. It is required to perform testing and verify the hardware functionality in order to gain confidence in operational implementation. Data acquisition during the performance acceptance testing is an essential requirement for any design validation by testing. If the system dynamics are changing rapidly the need for high speed measurements becomes essential such as in the case of jet engine fuel control system which is a dynamical system with fast transients of the order of few milliseconds. A better acquisition hardware and processing algorithm helped to reduce the latency in the acquired signals. Further, since there are multiple design test centers for fuel control system development, portability of data acquisition system aided in validating the subsystem with same standard of preparation at all centers prior to system integration.
