      and
      
      buttons.
   2. Press the Play button.

Printing a Signal

You can print from the Signal Browser using the Print button,

.

You can use the line display buttons to maximize the visual contrast between the signals by setting the line color for noise to gray and the line color for blnoise to white. Do this before printing two signals together.

Note    You can follow the same rules to print spectra, but you can't print filter responses directly from SPTool.

Use the Signal Browser region in the Preferences dialog box in SPTool to suppress printing of both the panner and the marker settings.

To print both signals, press the Print button in the Signal Browser toolbar.
