Abnormal errors of measuring time-frequency parameters of signals in wideband receivers: classification and methods of elimination

We propose the classification of abnormal errors in determining the time-frequency parameters in receivers used for the wideband RF spectrum sensing. The classification of errors made it possible to substantiate and systematize the ways to eliminate them. It is advisable to use the results in the design, debugging and operation of wideband spectrum analyzers. Based on the planned operating conditions, it becomes possible to predict the appearance of potential errors and take measures to eliminate them. Understanding the causes of errors makes it easier to configure and analyze the results of wideband spectrum analyzers.
