Designation

of FFT Spectrum analyzer ZET 038

Multi-functional FFT Spectrum analyzer ZET 038 is intended for parameters control of vibration, acoustic, and hydro-acoustic signals, as well as for generation of electrical signals with normalized metrological characteristics.

FFT Spectrum analyzer ZET-038 can be used in standalone mode, or within the scope of automated technological processes control systems, as well as for scientific and research purposes. Operating principle of ZET 038 series instruments is based on parallel (simultaneous) signals spectra analysis.

In the case if this instrument is used together with ZETLAB ANALIZ software, it becomes possible to use the following functions:

  • real-time signal analysis, analysis of the previously recorded signals;
  • octave and 1/3-octave analysis based on the use of parallel digital filters;
  • narrow-band spectral analysis;
  • AC/ DC voltage measurements;
  • electrical signals frequency measurements;
  • generation of sinusoidal signals and DC signals;
  • signals recording (the digitized values of the signal are saved in the memory of the device).

Information concerning the measurements parameters is displayed at the external devices in user-friendly format.

Note

When using FFT Spectrum analyzers of ZET 038 series, please note, that these instruments do not have automated blocking of the following ports: TCP 1808, 2320, 3344.
