All electrical components produce noise. A complex system, such as a receiver, represents the cumulative noise of its components. Noise Figure is one of the most useful metrics for characterizing the noise contributions of both components and the system as a whole. In practice, devices can be reliably differentiated by comparing this key parameter.
Our Spike spectrum analyzer software now includes a Noise Figure analysis mode. Download and read this Feature Overview for details and a walkthrough on how to make noise figure measurements.
