Abstract
A method and a device for increasing the dynamic range and measuring accuracy of a measuring device for spectrum and/or network analysis images a high-frequency electronic signal within a frequency range into at least two spectra through a first frequency translation by means of a mixer of the measuring device. As a result of the first frequency translation, the spectrum of the high-frequency electronic signal is successively imaged within the resolution bandwidth (ΔFZF) of an intermediate frequency filter of the measuring device. At the same time, through a second frequency translation, every spectral line of interference signals generated in the measuring device comes to be disposed outside the resolution bandwidth (ΔFZF) of the intermediate frequency filter.
