Viewing Collected Spectrum Data

After you have performed a survey, the spectrum data collected can be viewed in two ways. The first option is viewing data in the main application window. When you hover the mouse over any point of the walkabout path, the spectrum pane displays the graph for the given survey point. Because a meaningful chart must contain data collected over a certain period of time (typically one minute), the chart displays data collected during the time period starting -30 seconds prior to the selected walkabout path point and ending +30 seconds following the selected walkabout path point, or a total time span of one minute. If you analyze the points at the very beginning of the walkabout path, the time span shifts accordingly. For example, for the first point, the time span would start with the first second and end with the 60th second. The same principle works for the points at the very end of the walkabout path. When you move the mouse away from the walkabout path, the spectrum pane begins displaying live data again (if Wi-Spy is plugged in.)

The second option is viewing data in PDF or HTML reports. When a report with spectrum data is generated, location markers are overlaid on the floor plan and walkabout path, and a sequence of spectrum charts corresponding to each location marker is added to the report.
