View Mode
In the MX280005A program window, press the View Mode button. Use View mode to find the Points of Interest within a captured IQ data file. The Points of Interest window locates data points on the signal where power or modulation shifts occur. The results are displayed in the Points of Interest window as shown in Figure: Radar File - View Mode. The Points of Interest window is described in Table: Points of Interest.
