Convert Data	Opens the Convert Data dialog box to choose how to export .wdd data. If the file size is larger than the default buffer size set in the Preferences window, a dialog box prompts you to select a range of data. The data is downloaded from the WebDAQ storage location or mapped storage location to a location on the local drive on the computer specified by your browser settings. Select from the following data formats: .csv: exports a delimited ASCII text file. Additional options appear when .csv is selected: Decimal Places:* the number of decimal places to include in the exported data. Decimal Format: the decimal format to use when exporting data to a .csv file. Available options are Dot and Comma. Separator: the delimiter to use to separate each column of data when exporting to a .csv file. Available options are Comma (default), Semicolon, and Tab. Time Format: The mode used to indicate the duration of the acquisition on the x-axis. Select Absolute to display the x-axis based on the time of day when samples are acquired, or Relative to display the x-axis based on the time since the acquisition began. .uff(ASCII): exports both header information and data in ASCII text using Universal Dataset Number 58 formatting. Specify the data point precision (single or double), and each channel direction, if applicable. .uff(binary): exports header information in ASCII text and data in binary using Universal Dataset Number 58b formatting. Specify the data point precision (single or double), and each channel direction, if applicable. .bin: exports a binary file containing channel-interlaced double values; header information is removed.
launch Open File	Plots the selected data file on a strip chart, and switches the view from the File tab to the Display tab. Disabled when other file types are selected. If the file size is larger than the default buffer size set in the Preferences window, the Data Range Selector dialog box prompts you to select a range of data to plot. 10 MB is the default maximum data set for plotting. Selecting larger sizes is not recommended. To view other data in the file, use the Display options panel on the Display tab, discussed below.

tv Display

Use the Display tab to open files and view saved data.

When viewing FFT data, the maximum peak values are optionally displayed on the data plot and in the plot legend. The FFT size for display purposes is calculated based on the sample rate to achieve a resolution bandwidth of approximately 1 Hz. The FFT display is disabled by default when zoomed in on strip chart data.

Tap the gear icon next to the FFT plot to open FFT Plot Settings dialog box and apply a window type to each channel, show or hide the peak frequency, and set the spectrum type. Refer to the Customizing the FFT Plot topic for information about FFT display options.
