Windaq software is the flagship turn-key software package from DATAQ Instruments. It contains Windaq acquisition software and Windaq Waveform Browser.
Starting with Revision 3.16, which was released in April 2006, Windaq software can integrate 3rd party add-ons to its functionality.
Our Windaq Software Add-ons are designed to enhance the power of Windaq. With Windaq add-ons, you can add numerous functions to Windaq software without writing a single line of codes, for example, calculated channels, low-pass filter, spectrum display, closed-loop control, even audio commented event markers!
Operating System: Windows 98/Me/2000/XP/2003/Vista/Server 2008/7/NT
Supported Devices: DI-194, DI-154, DI-148, DI-158, DI-195B, DI-710, DI-715B, DI-718B, DI-718Bx, DI-720, DI-730, DI-788, DI-785, DI-1000TC, Transonic flow meter, any DATAQ hardware running Windaq.
To use Windaq add-ons
Make sure Windaq 3.16 or higher is installed on your computer
Confirm your Windaq is version 3.16 or higher
Restart Windaq, and you will find the Windaq add-ons integrated into Windaq->View->Add-ons menu (see above screen capture).
Intelligent Channel Selection: Highlight/Select a channel in Windaq and fire up the Windaq add-on you wish, and the Windaq add-on will use the selected channel as its default channel
If channel number is required for a Windaq add-on, please enter the 0-based index to Windaq's scanlist. For example, if Windaq has channel 3,4,6,7 enabled, one can enter 0 for channel 3, 1 for channel 4, 2 for channel 6 and 3 for channel 7.
Do not change Windaq's configurations while Windaq add-ons are running, or some add-ons may terminate.
30 Reasons You Should Register Windaq Add-on:
Windaq Add-ons Listed under Alphabetical Order:
-
Add-on Manager (ID=7016)
Use this to manage the add-on menu, removing unused add-ons from the menu
Note:- The new add-on menu takes effect on the next start of Windaq acquisition software
- The license takes effect on the next start of Windaq add-ons
- Menu items are sorted in both list boxes
- Multiple selection is supported (see above image)
-
Advanced Event (ID= 7010)
Advanced Event adds audio capability to the commented event marks feature of Windaq acquisition software.
Instead of typing in your text comment for events while recording data stream in Windaq, you may record your audio comment via the microphone of your PC!
Features of Advanced Event
- Support any microphone connected to your PC, as long as it is designated as default microphone input.
- Record hours of audio comment, and play it back in sync to the waveform with WWB Event Navigator
- Mark both the moment you start typing the text comment and the moment you push the insert button.
- If long (hours) audio comment is recorded, and the synchronization between comment and audio comment is important, due to WWB's time stamping method, it is recommended to start recording first, then pause and resume the recording right before inserting the audio comment.
- Please do not embed period in file name, for example, "My.Test.Wdq", or WWB Event Navigator will not be able to open it.
- Until Windaq enters record mode, you can't insert any verbal/text comment
- Bonus for users with paid registration: No ad-line in text box
-

To use the reading from a channel, use #n. For example, #0 is the reading from the first enabled channel in Windaq
To access the sample rate, use #@.
You can use earlier readings to form a more complicated math expression. To do so, add a letter after #, and alphabet order of the letter represents the delay, Such as:
-
#0 is the reading from channel 0
-
#A0 is the reading from channel 0, one scan earlier
-
#B1 is the reading from channel 1, two scans earlier
-
Readings from up to 26 scans earlier can be used, for example, #Z0.
-
For example: use ( #0-#A0)*#@ to form a two-point derivative
The output will be checked against the DAC limits of the device. If min or max limit is exceeded, the result is represented by color code, red for higher than MAX, green for lower than MIN, see above image for reference.

Event Navigator for Windaq Waveform Browser (ID=7031)
This
application is the advanced event
managing center for WWB to synchronize the analog waveform recorded in Windaq
and its audio/text comments. You can click on an event to jump to the
specific location of a waveform when the event for inserted. If the
event has audio comment created by Advanced Event ,
it will play back the audio comment. When WWB tracking option is
checked, it follows the cursor movement of WWB and
highlight/playback the comments when the cursor is on an event.
Features of WWB Event Navigator:
- Easy access to commented event markers: Unlike WWB's event markers' dialogue box, you don't need to close the dialogue box to move the cursor to the even marker.
- Click on an audio comment, it will move the cursor on WWB as the audio comment is played back
- If EarlyMark is checked, instead of move WWB cursor to the time of the text comment is inserted, it will move the WWB cursor to the location when you start to type in the text comment
- If Track WWB is checked, when you study the waveform in WWB, it will highlight the comment when the cursor is in the region of a comment. If the comment is audio-based, it will start to play back the comment based on the location of WWB cursor.
Notes:
- Due to the exclusive nature of the WWB link engine, only one copy of WWB FFT Viewr or WWB Advanced Event Navigator can be opened at any time
- If a Wdq file is being acquired to by Windaq Acquisition software, it should be closed first before it can be opened by WWB Event Navigator
- Non-standard HiRes and packed Pro+ Windaq files are not supported at this moment
- If .wdq file extension is not associated with WwbEventNavigator, you can start this program from Windaq\AddOn\WwbEventNavigator short cut
- Bonus for users with paid registration: No ad-line in event comment box

Provides Real-time 1024-point FFT power spectrum for frequency study. Due to the release of a newer and more powerful similar add-on called FFT II, this one is normally installed as hidden. Please use Windaq Add-on Manager to add it to Windaq's menu if you wish to use this add-on.
Click here for a video demo
FFT1024's resolution is about 10-bit, thus weak frequency components will be buried in the noise. To address this problem, Dynamic Amplifier option is created. When checked, waveform's average DC component is removed, then amplified to at least half dynamic range, before performing FFT. As the result, low level signal is much easier to study. Click here to see the effect of Dynamic Amplifier. This option becomes obsolete if you move to FFT II.
Analog oscilloscope-like persistence control helps to study the trend of the spectrum (Refer to the above screen shot for visual effect)

A Windaq add-on uses the free FFT1024 ActiveX control to visualize the frequency domain of an analog waveform in real-time, with 3D color-scaled waterfall spectrogram for history display. Due to the release of a newer and more powerful similar add-on called Spectrogram II, this one is normally installed as hidden. Please use Windaq Add-on Manager to add it to Windaq's menu if you wish to use this add-on.
Click here for a video demo
- While acquiring spectrum, you may use the mouse to drag the FFT spectrogram (in the upper chart) up and down, or double-click the buttons to change the scaling of the spectrogram.
- Once you stop the spectrogram, you may click on the spectrogram to enable a cursor and drag it horizontally to study the spectrum
- You may also click on the waterfall chart to enable a crosshair to show the frequency/elapsed time
- Waterfall chart is sizable for more history display
- Channel number is a 0-based index to Windaq's scanlist. For example, if Windaq has channel 3,4,6,7 enabled, one can enter 0 for channel 3, 1 for channel 4, 2 for channel 6 and 3 for channel 7.
-
Dynamic Amplifier option: FFT1024's
resolution is about 10-bit, thus weak frequency components will
be buried in the noise. To address this problem, Dynamic
Amplifier option is created. When checked, waveform's average DC component is removed, then
amplified to at least half dynamic range, before performing FFT. As
the result, low level signal is much easier to study. See below for
the demonstration. This option
becomes obsolete if you move to Spectrogram
II.
