List Of Included Daqarta Files


When you are exploring Daqarta, you may notice that there are numerous included files that can be opened from various dialogs. There are Generator setups, Spectrum curves, Arb waveforms, MIDI setups, and more. If you want to know what a particular file is used for, this list will direct you to the relevant Help topic.

The files are organized here by folder and file type. For example, Generator setups (.GEN file type) are all in the App_Data folder. Typically you don't need to know the folder name or file type since the Load Setup button defaults to showing all the .GEN files in the App_Data folder.

The lists here will help you find out more about a particular file, knowing only the name. However, note that .GEN files and MIDI setup (.DQM) files have alternative ways to find the relative links; see those sections below.

Documents - Daqarta - App_Data:

Generator Setup (.GEN) Files:

The following Generator Setup (.GEN) files are included with Daqarta and may be loaded via the Load Setup button in the Generator control dialog or the File menu. You may also Save modifications of these setups, or your own creations. However, note that many of the following are auto-loaded by macro mini-apps, which may not operate properly with a changed file.

Instead of using this list, you may alternatively just load a .GEN file and then right-click on the Generator Setup Title to see the relevant Help topic.

Frequency Counter Fcal Table (.TBL) Files:

The following .TBL files are selected via the Calibration Table button in the Fcal dialog of the Frequency Counter. They allow nonlinear sensors with frequency output circuits, such as thermocouples used with the Thermocouple To Frequency circuit, to be read directly in user units. The included files are for temperature sensors, whose units may be toggled between Celsius and Fahrenheit via the Fcal Units button. (You can create your own files for any unit type.)


Linear Sensors:

Spectrogrm Palette Files:

The following palette files may be loaded via the Load Pal button in the Color Palette dialog of the Spectrogram (Sgram) controls. They are standard Windows 256-color palette files with a .PAL extension, or a .PLT extension if you installed Daqarta to a folder other than the default.

Default.PAL        Color spectrum, red to violet to black
GrayScale.PAL      White to black (for printers)

Internal Daqarta Files:

For internal Daqarta use only; not user-viewable or editable:

Daqarta.DQM        Default MIDI setup
Daqarta.DQS        MIDI Scales
Daqarta.TXX        GlossyTracks MIDI Title Generator word list
Daqarta0.MAC       Default List of available macros

Documents - Daqarta - User_Data:

Headerless Data (.DAT) Files:

The following .DAT files are intended as Arb waveforms for use with the Generator, but can be opened as normal files via DD/Open for viewing or analysis. To do that, accept the default parameters in the DAT Format dialog. (That dialog appears when Daqarta encounters a file it can't identify.)

Files beginning with Arb_ were created with the Arb_From_Equation macro mini-app, and are discussed there along with waveform images and macro code for creating them. These are 16 kB files, but the default Daqarta screen only shows 1 kB without scrolling. To see the entire waveform at one time when opened this way, go to the X-Axis controls dialog and set Decimate on with Factor = 16.

Alternatively, you can actually use them as Arb waveforms and set the Tone Freq to 46.875 Hz (assuming the default 48000 Hz sample rate, else use SampleRate/1024). Set Tone Sync on (if not already) in the Tone Frequency dialog, then go to the Trigger controls dialog and set the Mode to Gen Sync. The waveform display will then show exactly one cycle of the Arb. (Plus, you can hear the sound of the file as well!)

Note that the final entry here (Expnote.DAT) is a special 1 kB file used with the Composer.GEN setup.

Daqarta Data (.DQA) Files:

The following files all pertain to engine crank/cam sensor simulation for ECM/ECU testing. The first was created manually using Creating Pulse-Train Arbs methods. The other 3 were created by the Engine_Sim Engine Crank and Cam Sensor Simulator macro mini-app.

Crank25-1.DQA              Engine crank sensor only, 25 teeth less 1

Engine36-1p@160_1p.DQA     36-tooth crank less 1, 1-tooth cam @160 deg

Text Data (.TXT) Files:

Bitmap (.BMP) Image Files:

Bitmap (.BMP) files are not a normal Daqarta data type (.DQA, .WAV. .DAT, or .TXT) so they don't display by default (and can't be opened with) the DD / Open button. You only see them with '*.BMP' in the Open dialog for Buf0-7 macro array file operations, as used by the BMP_to_WAV macro mini-app. This converts a bitmap image to a .WAV file whose spectrogram reproduces the original image in full color. The files below are all the same image, with different color resolutions:
