FFT Analysis Software
DS-0321A
DS-0321
The DS-0321 is basic software for frequency analysis. With this software, you can resolve time-axis 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.
·The measurement waveform on the screen starts to move immediately after the activation of software. (Easy to see screen data)
·Various measurement conditions can be changed during checking the real-time measurement screen.
·Only the necessary setting items can be registered according to the needs.
Features
New function
Multi-channel measurement system up to 128 channels can be temporarily build up by using unit connection function ”FRAME LINK 2. Up to 4 units of the DS-3000 series are able to be connected. Unit connection USB Hub (DS-0393) allows multiple USB connection even if a PC does not have enough USB terminals.
●Up to 1024 pairs of cross calculation channels can now be registered
The registration number of cross calculation channels has been increased from 128 to 1024 pairs.
●UNIT-CH information display
Even when you start up the system with two units or more, you can find which signal is input to which channel of unit by the UNIT-CH information display in < Input Condition Setting> dialogue.
