PQDiffractor® is a free PQDIF viewer and free COMTRADE viewer written by Electrotek Concepts for viewing, browsing, diagnosing, and converting PQDIF files and COMTRADE files, and is a free software download from www.pqview.com.
The COMTRADE file viewer was updated to read the last analog or digital channel of the COMTRADE file. Previous versions would set all values to null for the last channel.
The following menu commands were added to the Window menu when using the PQDIF viewer and the COMTADE Viewer: Tile Horizontally, Tile Vertically, Cascade, and Arrange Icons.
The Close All menu command did not work when viewing COMTRADE files. This was corrected.
