12.6.4 REPRESENTING POLAR DATA To represent the measured data we need to enter the Directivity Settings dialog and press the browse button. Entering our data directory we find the situation in Fig.12.15: Figure 12.15 The set of files is composed by 73 files; it is sufficient to choose one of them. It is now important to identify the initial and last files for display, this is done with the Z-start and Z-stop values to be input as in Fig.12.16. We choose to display all responses from -180° to +180°, take the response on axis as reference and choose frequency limits from 150Hz to 15kHz. Figure 12.16 We are, at last, ready to start a directivity analysis. The results are in Fig. 12.16 both as color map and 3-D plot. Figure 12.16 Treating polar data we may be more interested in referencing the graph to the response that our speaker shows on-axis. This is easily done pressing the reference button and executing the processing again. 154 Chapter 12 - Waterfall and Directivity
The final result for our polar data waterfall is in Fig.12.17; the response at 0 degrees is now flat and our plot perfectly identifies the behavior of the speaker, providing clear evidence of the different behavior of the polar response versus different frequency zones. Figure 12.17 Another way to view the same data are the classical circular polar plots. To achieve this ulterior result simply press the Polar Pattern button. Then you may change analysis frequency with the dedicated arrow buttons and save the polar patterns of interest in different overlays reaching a situation like the one in Fig.12.18.
