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-0221 general-purpose FFT analysis software, DS-0223 real-time 1/1 and 1/3 octave analysis software, and DS-0224 real-time 1/N octave analysis software. You can analyze and process those digital data using a single PC only without connecting to DS-2000 series.

Once connecting the main unit of DS-2000 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-0250 has V, W, or X at the end of the model name according to its number of channels. DS-0250V is available for 2-ch, DS-0250W is for 4 to 8-ch, and DS-0250X is 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 2000/XP/VISTA) is required as an operating system.
