FFT Analysis Software
DS0321
The DS0321 is basic software for frequency analysis. With this software, you can resolve timeaxis waveform into each frequency, and observe the level of each component. It fits the purpose of resonance frequency observation or careful observation of sound frequency component.
·Illustration in which measured waveform starts to move immediately after the software starts. (Easy to use software screen data)
·Various measurement condition can be changed while watching realtime measurement screen.
·Only the necessary setting items can be registered according to the needs.
This is easytouse software with onsite measurement with limited time.
