The Advanced Swept Sine Solution (A2S) is part of the NVSolutions® proposed by OROS for Noise and Vibration applications. Advanced Swept Sine is a measuring instrument that allows to determine Transfer Function or Frequency Response Function that are commonly used in various industries for Servo control, Structure, Acoustics, Electronics or Accelerometers calibration.
The challenges for determining the Frequency Response are the frequency resolution, an excitation level control (control of the energy transferred to the system, enough for getting a good signal/noise ratio, but not too much for avoiding non-linear phenomena) and speed of the measurement
A2S gives the most adapted answer to these requests, and compared to the standard functions included in a FFT analyzer, A2S dramatically overpasses the capabilities of a random or swept sine excitation coupled with a peak hold FFT.
Main features are:
- High precision and very low noise frequency response function determination
- High frequency resolution: continuous sweep up to 80 000 points
- Pure tone excitation
- Frequency range from 0.01 Hz to 40 kHz, in 1 to 8 independent spans
- Automatic control of the generator output level to get constant level either at input or output system under test
- User defined level/frequency template
- Boosted mode to speed up the measurement
- Display Frequency Response, Coherence, Spectrum
- Bode and Nyquist plots
- Export to Excel, Matlab and others
