Spectrum analyser SK4M-18A/3

Spectrum analyser SK4M-18A is designed to measure levels and frequencies of harmonic components of the spectrum of periodic signals, as well as the 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.
