Spectrum analyser SK4M-18A/4

Spectrum analyser SK4M-18A/4 is designed to measure levels and frequencies of harmonic components of the spectrum of periodic signals, as well as power spectral density of stationary random processes. The use of a linear path with a wide dynamic range, made according to the superheterodyne scheme with synthesised heterodynes, in combination with a block of digital processing of the intermediate frequency signal allows solving a wide range of problems arising in research, development, production and operation of modern radio-electronic devices.
