SPIRAS
Multi-purpose Dynamic Data Acquisition/Processing Software

Summary

Enable high-speed dynamic data acquisition in 8 to 128 channels
The software is designed to record and process dynamic variables of strain, pressure, acceleration and displacement.
During data acquisition by sampling at a maximum 100 kHz, the software enables users to monitor the data in waveforms, X-Y graphs and numerics. If the sampling rate is 2 kHz or lower, frequency analysis result too can be monitored. (In any case, a sampling rate exceeding 2 kHz thins out graphs.)
In data processing, calculation between channels, digital filtering and statistic processing are available while frequency analysis and histogram analysis are optional. Furthermore, if a movie was taken during data acquisition, it can be reviewed in synchronization with graphic and numeric data.
The software is applicable to EDX-100A as standard but can be made applicable to EDX-3000A, UCAM-550A or EDS-400A according to user’s needs. In addition, we can offer versions for simultaneous measurement of static and dynamic data, etc. as desired.

Features

●Monitor real-time data sampled at 100 kHz in waveforms, X-Y graphs and numerics.
●Monitor real-time frequency analysis of data sampled at 2 kHz.
●Present waveforms, X-Y graphs, frequency analysis graphs in desired layout on the display.
●In data processing, graphic and numeric data can be displayed in synchronization with a movie.
●Enable calculation between channels, digital filtering and statistic processing.
●Enable file output in CSV format.
●May be revised individually according to user’s needs.
