Spectrum Viewer
This program reads and displays XY-plots (up to 500 at a time) into an X-Y graph or into a 2D intensity plot.
Furthermore signal conditioning can be done: smoothing, powerful spike elimination, and averaging multiple sets into one. Some analysis is supported, like peak area, subtracting a hand drawn background, full width half max, histogram of Y values, differentiation (per data point or smoothed), integration and logging. The program can also be used as a measure program display; with DDE you can make other programs control Spectrum Viewer. After measuring, SV can automatically open and display your measured file.
