Integrate/Differentiate
These commands are available only for results with an X-Axis that represents frequency lines. The operations are performed in the spectral domain.
- Normal: No operation is performed on the data
- dt: The result is integrated, so that acceleration becomes velocity. The following formula used is:
- dt²: The result is integrated twice, so that acceleration becomes displacement. The following formula used is:
- dx/dt: The result is derived, so that velocity becomes acceleration. The following formula used is:
- dx/dt²: The result is derived twice, so that displacement becomes acceleration. The following formula used is:
Unit
These commands are available only for results with an X-Axis that represents frequencies. The operations are performed in the spectral domain.
- RMS: Provides the RMS (EU) value. This is the default unit.
- Peak: It is based on a sine signal, and therefore equal to 1.414 times the RMS value.
- Peak-Peak: It is based on a sine signal, and therefore equal to 2.828 times RMS value.
- EU²: Means Square value.
- PSD (EU²/Hz): Calculates the Power Spectral Density of the result. The formula used is:
Where ENBW is the Equivalent Noise Band Width that takes into account the weighting windows (1 for Rectangular, 1.5 for Hanning, 1.36 for Hamming, 3.77 for Flat top) and val the RMS value.
- ESD (EU²/Hz²): Calculates the Energy Spectral Density of the result. The formula used is:
Where ENBW is the Equivalent Noise Band Width that takes into account the weighting windows (1 for Rectangular, 1.5 for Hanning, 1.36 for Hamming, 3.77 for Flat top) and val the RMS value.
- RMS PSD (EU/Hz1/2): Calculates the RMS Power Spectral Density of the result. The formula used is:
Where ENBW is the Equivalent Noise Band Width that takes into account the weighting windows (1 for Rectangular, 1.5 for Hanning, 1.36 for Hamming, 3.77 for Flat top) and val the RMS value.
