Analysis of dynamic processes, vibrations
- multichannel processing of vibration, pressure pulsation, noise, etc.;
- assessment of vibration condition of rotary machines (stationary regime);
- calculation of parameters at run-modes / freewheel
- processing strain measurements;
- processing of audio signals;
- treatment of pressure pulsations, noise.
Construction of signal characteristics depending on the time or in relation to the signals of the sensor speed (taco signal):
- Taco characteristic;
- amplitude / rms / magnitude / phase harmonic;
- amplitude / rms / scale / scope of the frequency;
- amplitude / rms / scale;
- expectation;
- low-frequency vibration;
- CPS in the band;
- spectral analysis.
Campbell diagram
Campbell diagram is used to analyze dynamic processes. It shows the dependence of the frequency peaks in the spectrum of the speed. The values are drawn as dots, vertical lines or circles. Height and diameter of the circle lines depend on the value of the signal (RMS, amplitude, or amplitude).

Sequence analysis
Sequence analysis applied to the analysis of dynamic processes, mainly in non-stationary, such as coasting or run. The result of calculation is a three-dimensional signal in which the X-axis delayed frequency spectrum or a multiplicity of harmonics, the Z speed or time, and on Y - the amplitude, sweep, or CPS.
