DADiSP / Dataq File 5.1
Dataq File Import/Export Module
A WDQ, WDC or WDH file is a 16 bit binary data file format created by Dataq
data conversion hardware and software. Dataq files can contain one
or more channels and include amplitude units and scaling parameters
to convert raw A/D counts to engineering output data.
Simple Import Interface
Importing a Dataq file is as simple as pressing a button and
selecting the file. After a file is chosen, a summary of the
contents is displayed. The data channels are transposed on the fly
to take advantage of DADiSP's optimized column orientation.
The channels can be loaded into separate Windows or combined into a
single Window for display. Individual channel names are displayed
and any combination can be selected for loading. The data can be
converted to original engineering units or imported as raw A/D
counts. The transfer buffer size can be specified for read
optimization of large files.
Simple Export Interface
Multiple DADiSP series can be exported to a single WDQ file simply
by selecting a file name and checking a list of Windows to save.
Sample rate, engineering units and scaling information for each
series are automatically saved.
Each DADiSP series can be autoscaled to make use of the maximum
output resolution or a specific input A/D range can be specified to
facilitate use with a specific A/D converter. The transfer buffer
size can be specified for write optimization of large WDQ files.
WDQ/WDC/WDH File Format
A WDQ/WDC/WDH file contains 16 bit integer data with 14 bit precision.
Sample rate, engineering units and double precision scaling
parameters are also saved with the A/D count values. DADiSP/Dataq
File relies on Dataq's ActiveX control to isolate format details
and eliminate file incompatibilities.
DADiSP/Dataq File requires DADiSP 6.7 B01
for information about updating your current
version of DADiSP.
