General-purpose FFT Analysis Software


2 ch/4 to 8 ch/10 to 32 ch

Replaces with DS-0221 Sereis


Supported Hardware


The DS-0221A series is basic FFT analysis software. Each model has V, W, or X at the end of the model name according to its number of channels. DS-0221VA is for 2-ch, DS-0221WA is for 4 to 8-ch, and DS-0221XA is for 10 to 32-ch. Connecting DS-3000 main unit to PC under operating environment for Windows (Windows XP / VISTA/ 7 ), frequency analysis with high-accuracy (more than 100dB for dynamic range), high-resolution (maximum at 6400 FFT lines) and high-speed (real-time analysis frequency range; 40kHz/4-ch) can be performed. User-friendliness in a unified with Windows-based software enables easy operation such as copy and paste of data.
