    Development of generic test algorithms for broadband RF and microwave components can be challenging due to the wide variances in device properties. Test assumptions, which are suitable for devices with tightly constrained setup and operating ranges, tend to break down when generalized to the broader population of microwave devices. These difficulties are compounded when dealing with high power com... View full abstract»

    The generation of quality RF/Microwave Test Program Sets (TPS) has always been a technically challenging and expensive task. The lack of an RF/microwave test simulator makes the generation of test and diagnostic vectors a very time consuming task. RF/microwave components exhibit multiple fault modes, i.e. gain, noise figure, etc..., as compared to the “1” or “0” fault mode ... View full abstract»

    Model based diagnostic systems have generally avoided the issue of multiple failure diagnosis due to the computational complexity of covering all possible multiple faults and still providing an efficient diagnostic strategy. Optimization of decision trees is already known to be NP-complete, and the number of combinations of multiple faults just serves to exacerbate the problem. Nevertheless, model... View full abstract»
