About This Product
Input channel 4ch fixed compact size
■ Time waveform
The time waveform is displayed in the number of samples (FFT analysis points). When the time waveform is recorded, the recorded all -time waveforms can be displayed, and various secondary operations can be performed from the recorded waveform.
■ FFT analysis
By converting a high -speed Fourier conversion (FFT) of a composite signal that looks irregular in time, the frequency spectrum analysis contained in the signal is performed by discovering the regular regularity.
■ Time waveform recording
It is a function to save time waveforms in memory of the computer, and the time available is determined by the computer memory, the number of input channels, and frequency range.
■ Power spectrum map / octhabmap
Use the power spectrum and octavid analysis results to display the size of the horizontal axis, the frequency on the vertical axis, and the difference in color.
■ Transmission function / coherence function
-The transmission function shows the ratio of the frequency area of the input signal and the output signal, and is displayed as a amplitude and phase.
-The coherence function is calculated in the frequency area for the similarity of the two signals, and is displayed in the numbers between 0 and 1. It is used as an evaluation of the transmission function and is effective in fields such as S/N measurement and sound source contribution rate.
■ octa Band analysis
The relationship where the frequency ratio is 1: 2 is called octave, and a filter with a maximum frequency of the bandpass filter twice the lower limit frequency is called the octave band pass filter. For analysis for evaluation and countermeasures at the noise level and vibration level, it is common to use octave band analysis that is easy to respond to human sensations.
■ Recall operation
From the octa -band analysis results, secondary operations are performed.
■ Incarnation display
You can display multiple FFT analysis results repeatedly. It is effective before, after the countermeasures, after seeing OK / NG data.
・ Switching probability density function
・ Self -correlation function
・ Mutual joint function
