This function enables count waveform generation such as level, edge or variation waveform and is ideal for the use of changing rotational pulse signal into angle or distance waveform.
This function enables to obtain the effective value (RMS value) trend of a specified time-series waveform.
Frequency weighting correction, time constant, and output time interval can be specified.
The result of RMS can be output as a linear value. Frequency weighting corrections can be selected from A-weighting, C-weighting, Z-weighting and G-weighting. (G-weighting is frequency correction characteristics for evaluating affect of micro low frequency (standardized in ISO7196:1995) to human senses.)
To check the effect of fluctuation sound, the frequency band component of the sound had to be increased and decreased by bandpass filter. So it cannot help changing the frequency characteristics of the sound.
The fluctuation sound simulator removes and amplifies only the fluctuation components of the sound without changing frequency characteristics.
You can extract the specified component when you want to check just the fluctuation component.
In Parametric Equalizer, not only frequency filter but also order filter is available. Order Filter is the filter for frequency of noise or vibration that changes according to the variation of rotation speed in rotation equipments including engine and compressor. Only noise and vibration that is generated from the specific rotating body can be extracted, removed, and evaluated.
The example of using BRF (Band reject filter) is as follows when the center frequency is 100 Hz and the order is third.
When the center frequency of the BPF is 100 Hz, the center frequency of the filter remains 100 Hz even if the rotation speed of the rotating body varies from 2000 r/min to 8000 r/min. On the other hand, the center frequency of the BRF changes depending on the rotation speed when the order is third; BRF for the center frequency100 Hz at 2000 r/min, BPF for the center frequency 400 Hz at 8000 r/min. Only the noise or vibration generated from the specific rotating body that has found in tracking analysis can be filtered.
Synchronizer is a function for aligning the positions of waveforms. For example, when the recording start times of measurement data are misaligned, but start trigger signals were recorded for the respective channels, you can adjust the waveform to align the positions of the start trigger signals.
You can align the positions of plural time-series waveforms in terms of setting a threshold.
