DAPstudio 2.5 displays live data in several formats, including bar graph, line graph and waterfall. Each format has an optional 3-D view to observe different shapes on different channels. The waterfall line-graph implementation gives a quick overview of millions of data points through a moving window, and lets users look at spectra over both frequency and time simultaneously. Optional rotating colors for the waveforms in a waterfall graph allow a specific spectrum to move back in time with the same color. Additionally, the software facilitates the development if a PC-based measurement system with one or more DAP boards.
