DADiSP Software
Module - DADiSP / Dataq File 3.0
 Dataq File Import/Export Module Updated
DADiSP / Dataq File is a simple dialog based module designed to easily
read and write Dataq data files. Dataq files can be of any size and
contain any number of channels.
The ReadDataq dialog automatically reads all the channels in a Dataq
WDQ, WDC or WDH 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 Dialog Box User Interface
- Reads and writes Dataq files of any size
- Buffered data I/O to support huge data files
- Optimized series processing for fast loading of Dataq files
- Reads scaled engineering units data or raw A/D counts
- Writes autoscaled data or user specified A/D input range
New Features
DADiSP/Dataq Version 3.0 has been updated to support Dataq WDC and WDH file
formats. A simple dialog box interface makes selecting and reading any file
as simple has clicking a button.
Multichannel data can be displayed in multiple windows. The new stripchart
feature allows multiple channels to be displayed in a single window with
individual axes for each channel. Scroll and zoom operations are automatically
synchronized to provide easy cross-channel inspection.
New optimized buffered I/O enables the reading of huge files with minimum
memory requirements and optimal speed.
Dataq 3.0 New Features Summary
- Updated WDC and WDH File Read Support
- Optional Single Window Stripchart

- Buffered I/O to Optimize Huge Files
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.
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 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.
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 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 Dataq Acquisition
Device File relies on Dataq's ActiveX control to isolate format details
and eliminate file incompatibilities.
 Requirements
DADiSP/Dataq File requires DADiSP 6.0 B17 or higher. Contact us for information
about updating your current version of DADiSP.
DADiSP / Dataq File 3.0 Functions
DADiSP/Dataq File is a fully menu driven
module. However, the following functions can be used on a standalone basis
to read WDQ/WDC/WDH files and write WDQ files.
| Dataq File Functions |
| rdaqmenu |
Displays the dialog box interface to read Dataq files. |
| readdaq |
Loads a Dataq WDQ/WDC/WDH file. |
| wdaqmenu |
Displays the dialog box interface to write Dataq files. |
| writedaq |
Saves multiple series to a Dataq WDQ file. |
