XN-8000 Frequently Asked Questions

This means that it is possible to change the frequency range and analyze simultaneously. An example of FFT analysis software is as follows. The same is possible with tracking analysis.

Example 1

In the analysis system of Figure 1, the signal of ch1 can be analyzed simultaneously with FFT11 and FFT12.
The frequency range of FFT11 is set to 500Hz, and the frequency range of FFT12 is set to 20kHz. Additionally, the measurement paper displays the power spectra of FFT11 and FFT12 respectively. The measurement data is simultaneously measured with a resolution of 800 lines, with FFT11 covering 0 to 500Hz and FFT12 covering 0 to 20kHz. An example graph is shown in Figure 2.

■Example 2

In the analysis system of Figure 3, ch1 can be analyzed simultaneously with FFT11, and ch2 with FFT12. For example, ch1 can input a microphone signal, and ch2 can input a vibration acceleration signal, allowing for the setting of different frequency ranges and simultaneous FFT analysis.
