of A19-U2 FFT spectrum analyzer

FFT spectrum analyzer A19-U2 allows to simultaneously use several programs for analysis and signal mapping. This allows to create various complexes for testing, process monitoring, and control systems.

The combined use of several programs allows to carry out tests in non-stationary modes.

The spectrum analyzers are used for vibration and acoustic measurements, continuous monitoring, machinery diagnostics, test equipment control, adjusting the process parameters, automating acceptance tests, etc.

Different designs (laboratory, portable, industrial, submerged, etc.) and PC interfaces facilitate the use of  FFT spectrum analyzer in stationary, mobile, self-contained, industrial, distributed and dynamic systems in various environmental conditions.
