The hard disk recording capability of the recently introduced DL850 ScopeCorder has been boosted by an advanced file utility option in the Xviewer waveform display and analysis software from Yokogawa Australia . The new utility allows an engineer to pre-analyse waveform data while acquisition is still in progress.
The new DL850 advanced file utility option for Xviewer uses a file transfer tool to transfer recorded data files from the DL850 to a PC without interrupting actual hard disk recording.
This utility tool enables engineers on the production line to pre-analyse measurement data using Xviewer on the first day of recording rather than wait until the end of the recording period or stop the measurement mid-way to access the data.
During hard disk recording, the DL850 divides measurement files into smaller files, which are automatically transferred to a PC through an Ethernet or USB connection during real-time recording. These files can be analysed using the dedicated Xviewer software while the actual measurement is on.
The file utility tool adds file merging, divide and conversion functions that enable smooth file handling of DL850 waveform files using Xviewer.
A typical application might be an electro-mechanical process on a production line on which two signals have to be monitored over a period of 14 days at a sample rate of 10 kS/s.
Without hard disk recording, the DL850 with the 2GPoint memory option can measure for 20 hours under these conditions. When the hard disk recording option is used, it becomes possible to measure for a full 20 days.
With the new advanced file utility tool, engineers on the production line can pre-analyse measurement data using Xviewer on the first day of recording rather than having to wait another 19 days. The analysis can be conducted while the DL850 is still simultaneously recording in the background.
The file utility tool allows merging of multiple DL850 data files into a single file, divided by time order or recorded across multiple channels or multiple DL850 units. Long recorded data files can also be divided into multiple smaller files. The file can be equally divided or any portion can be extracted and resaved.
Binary data files recorded by a DL850 can also be converted into CSV or floating format, which in turn can be imported into programs like MATLAB and MS Excel.
