Noise figure is an important figure-of-merit that describes the amount of excess noise present in a component or system. Minimizing noise figure reduces system impairments that result from noise, such as degraded voice quality of cell-phone calls, or decreased detection range of radar systems. Measurement accuracy is very important, in both R&D and manufacturing environments. In R&D, better noise figure accuracy means that there will be a better correlation between simulations and measurements, helping designers refine circuit models faster. In manufacturing, improved accuracy provides better correlation among multiple test stations, minimizing rework and increasing test throughput. Higher accuracy also allows better device specifications, yielding more competitive products.
