Improved Methods for Measuring Distortion in Broadband Devices - Application Note
This paper illustrates that, in broadband commercial and defense systems, it is more important than ever to characterize them for non-linearity. It is also important to understand the mechanisms that create these non-linearities and the characteristics of the waveforms that cause them. We focus on the primary tests used to determine the level of a system’s distortion products and how they result in Intermodulation Distortion (IMD) and Intermodulation Distortion Noise (IMDN). Looking at the method to evaluate the effect of IMD in a communication system under real data traffic conditions, Noise Power Ratio (NPR), we see measures of the IMD as a function of data traffic conditions in a wideband or multi-channel communications channel.
