DADiSP Software
Module - DADiSP/Dataq File 2.0
Dataq WDQ File Import/Export Module
DADiSP/Dataq File is a simple dialog based module designed to easily read
and write Dataq WDQ data files. WDQ files can be of any size and contain
any number of channels.
The ReadDataq dialog automatically reads all the channels in a WDQ file
and optionally scales the data and sets the sample rate and engineering
units.
The WriteDataq dialog saves one or more DADiSP series to a WDQ data file.
Sample rate, engineering units and conversion parameters are automtically
included.
Key Features
- Simple Dialogue Box User Interface
- Reads and writes WDQ files of any size
- Buffered data I/O to support huge WDQ data files
- Optimised processing for fast loading of WDQ files
- Reads scaled engineering units data or raw A/D counts
- Writes autoscaled data or user specified A/D input range
Dataq WDQ File Import/Export Module
A WDQ file is a 16 bit binary data file format created by Dataq data conversion
hardware and software. WDQ 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 WDQ 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
optimised column orientation.
Import Options
The channels can be loaded into separate Windows or combined into a single
Window for display. 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 optimisation of large WDQ 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.
Export Options
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 optimisation of large WDQ files.
WDQ File Format
A WDQ 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 Dataq Acquisition Device
File relies on Dataq's ActiveX control to isolate format details and eliminate
file incompatibilities.
DADiSP/Dataq File 2.0 Functions
DADiSP/Dataq File is a fully menu driven module. However, the following
functions can be used on a standalone basis to read and write WDQ files.
| rdaqmenu |
Displays the dialog box interface to read Dataq files. |
| readdaq |
Loads a Dataq WDQ file. |
| wdaqmenu |
Displays the dialog box interface to write Dataq files. |
| writedaq |
Saves multiple series to a Dataq WDQ file. |
System Requirements
DADiSP/Dataq File requires DADiSP
6.0 B17 or higher. Contact
us for information about updating your current version of DADiSP.
