WinDaq Waveform Browser contains a file conversion utility that allows you to convert other data files to the CODAS data format. This enables data files from other sources such as ASYSTANT, DADiSP, or any other spreadsheet program to be viewed and/or otherwise analyzed in WinDaq Waveform Browser.
The convert program (hereafter referred to as CONVERT) is a DOS utility that can be executed from within the WinDaq Waveform Browser by choosing File Open and entering the input file (or non-CODAS file you wish to convert) in the Filename: text box. Make sure the proper input file format is selected from the list on the right side of the dialog box and choose SAVE.
When an input file is entered, the Convert Output Open dialog box is displayed, prompting you to select the proper input file format and specify an output file name. We recommend using the same file name as the input but with a different extension, like .WDQ to indicate that the original file has been converted to a WinDaq Waveform Browser file. When an output file name has been specified and the proper input file format is selected, choose SAVE.
After some initial file identification, CONVERT prompts you for details about the file you are converting. These details consist of: the number of channels in the file, the sample rate, the ± full scale channel values, and the units specified per channel. Not all conversions will require that you input every one of these parameters. For example, if you are converting a DADiSP floating point file, you will not have to enter any of these parameters since this information is already contained in the DADiSP file header and therefore readily available for CONVERT to use. You will be prompted for these parameters only when they are not available in the original file. The following table shows the parameters for which CONVERT will prompt, depending on the type of file you are converting.

* Prompts if no sample rate has been entered in the original file.
# Prompts if no units have been entered in DADiSP.
Instructions for entering values and moving between fields are displayed onscreen. It is important to enter the same values from the original file to ensure an accurate conversion. When the necessary parameters have been entered, press ENTER to accept and convert the data file. When the file has been successfully converted, it will be displayed on your screen in the WinDaq Waveform Browser ready for review.
