Displaying the composite spectrum

8

NOTE: For information on acquiring PSD spectra, see the Voyager Biospectrometry Workstation User’s Guide.

NOTE: You cannot display the PSD data you are currently acquiring in the Instrument Control Panel in the Data Explorer software until you stop the PSD experiment in the Instrument Control Panel. Error messages are displayed if you try to open the file. For more information, see the Voyager Biospectrometry Workstation User’s Guide.

To display PSD data:

1.Open the PSD data file of interest in the Data Explorer software as described in Section 2.1, Opening and Closing Data Files.

NOTE: PSD data files are named with a .DAT extension. When you acquire PSD data files, include a _PSD suffix when you name PSD data files, for example, Test_PSD, to help you distinguish them from non-PSD data files.

The composite spectrum is generated as described in “How the composite spectrum is generated” on

page 8-6,and displayed with a Stitched PSD trace label (Figure 8-1).
