Macros: Label1-Label6

There are 6 Label windows below the Notes area. Together with the matching Fields below them, they may be used instead of Notes to supply information that will be saved along with the trace data when you save a .DQA file, or save to Juxt Array memory.

For example, if you are recording responses to a particular stimulus, you might want to label each response trace with the stimulus frequency, sound level, and burst duration used for that trace. In this case, the Labels might be Freq, SPL, and Duration. The Fields below these would hold the actual values of these parameters. Macros can be used to update Fields automatically, whenever the relevant parameters are changed.

Typically, you might use the same Labels for a number of traces, while the corresponding Fields would naturally change with each trace.

Daqarta can preset the Labels from a file called Daqarta0.LBL which is automatically loaded if found at start-up. You will be prompted to save the current Labels to this file if any of them have been changed before you exit Daqarta.

Alternatively, you may load other DaqartaN.LBL files at startup, where N is any alphanumeric character, by invoking Daqarta using the L:N parameter. You can create separate desktop icons that load different Label sets for different purposes.

Assuming you have a desktop icon from a standard Daqarta installation, first create a copy by right-clicking and selecting Create Shortcut.

After the new icon appears on your desktop, right-click it and select Properties. Under the Shortcut tab, the Target line will show something like:

"C:\Program Files\Daqarta\Daqarta.exe"

Add the L: parameter at the end of that line (outside of the quotes). For example, to load Daqarta1.LBL you would change the above to:

"C:\Program Files\Daqarta\Daqarta.exe" L:1

Although Labels are intended to label the Fields beneath them, they may be used just like Fields to store relevant data if you need more than the 6 Fields available. In such cases it is helpful to always use the same layout, so you can later identify each unlabeled entry. A system of macros can make this easier, by prompting you for manual entries (like test number) and by automatically copying other values, storing each in its specific location.

Note: In 640x480 display mode the main window is too large to see Labels or Fields. Although unseen, you can still send data to these via macros. If you save a .DQA file, those Labels and Fields can be seen later on any system with a higher screen resolution.

Macro Notes:

Label1=Freq sets Label1 to Freq. Use quotes if the text includes embedded spaces, such as Label2="dB SPL".

As for Fields, you can specify that any Label receive a copy of a given variable whenever that variable is displayed or changed. For example, Label1=?SmplRate will cause Sample Rate to be copied to Label1 whenever it is shown or changed.
