With this throughput disk function, the digital signal which the analog signal was transformed by A/D converter can be recorded continuously in the HDD of the PC. The maximum size of 4 GB per one file can be recorded.

The digital data which is recorded by the throughput disk function can be recalled and analyzed by DS-0221A Series general-purpose FFT analysis software,DS-0222A Series tracking analysis software, DS-0223A Series real-time 1/1 and 1/3 octave analysis software, and DS-0224A real-time 1/N octave analysis software. You can analyze and process those digital data using a single PC only without connecting to DS-3000 series.

Once connecting the main unit of DS-3000 series to the PC and recording the signal from the sensor on site continuously, you can bring it back and analyze the data at your leisure. DS-0250A has V, W, or X at the end of the model name according to its number of channels. DS-0250VA is available for 2-ch, DS-0250WA is for 4 to 8-ch, and DS-0250XAs for 10 to 32-ch.

The data is recorded by the extension of ORF, ONO SOKKI’s original file format. However, the data can be transformed into the WAV, text, DADISP, MATLAB, and UFF by using DS-0251 file export function. Windows (Windows XP / VISTA / 7 ) is required as an operating system.
