Use the Save Screen Image tab of the Specify Report Action for Limit Test dialog to save a screen capture of the graticule area to a graphics file for a limit test. Close the dialog to return to the Limit Test dialog.

To open this dialog, click Specify Reporting Action… in the limit-line setup dialog.

Select Save Screen to save a screen capture. The screen image allows you to see what the waveform image looked like at the time the limit test stopped.

Select Monochrome to save the screen as a black and white image.

Select Invert Graticule Area Background Color to save the image file's background color as white (the original color is black). The waveform colors remain unchanged. This option is especially useful when printing the waveform. The background of the printed image will be white; the waveform color will vary depending on the printer available (black and white, or color).

In the Include in screen capture field, select the display area to capture: Entire Display or Only Waveform Window. The following screen captures show the output from these two selections.

Available Graphics Formats

Click Browse to enter a starting filename and the file format:

• .png. A popular format for documents and the web.
• .jpg (24-bit color Joint Photographic Experts Group file format). A graphics format which can be highly compressed. This compression can result in permanent loss of image quality.

• .gif (Graphics Interchange File format). A standard graphics format (256 color) used to store symbol mapped graphic files.

• .tiff (24-bit color Tag Image File format). A format of choice for storing images with lossless compression. It provides better quality, but larger files. This format is widely supported across platforms (PC, Mac, UNIX).
