Let's now change the CSD aspect again. Go to the waterfall settings dialog and check the Reference box. After recalculating, you obtain the plot in Fig.12.8; as you notice now the slices are referenced to the first one (the rearmost); decays of different frequency regions can now be more easily compared. Now change the Windows Rise Time from the default 0.58ms to 0.1ms and recalculate the CSD. The result is given in figure 12.9. Figure 12.8 Figure 12.9 122 Chapter 12 - Waterfall
12.5 MEASURING AND REPRESENTING LOUDSPEAKER POLAR DATA Suppose now we want to measure and give a graphical representation of the polar response of the same speaker analyzed in 12.4. We need to measure its anechoic frequency response, at various angles, with MLS and save the files following the rules given in 12.3.2. We will use a turntable (Outline ET/ST), under <strong>CLIOwin</strong>'s control, and the automation possible within the MLS control panel. 12.5.1 PREPARING THE MLS CONTROL PANEL For this test we would like to measure the speaker from -60° to +60° (in intervals of 5°) relative to its front baffle. The MLS measurement should be set in a particular way in order to automatically acquire the responses at various horizontal angles. To do this we will use the autosave function, the loop mode and the link to the turntable control. Let's start from setting the autosave function. Pressing Alt-F2 we recall the Autosave Setting dialog (fig.12.10); here we input the desired filename ('rcf deg'), start (-60) increment (5) and total (25) values. Figure 12.10 The MLS menu is now ready to start taking measurements; we only need to properly set the turntable and its control. 12.5.2 PREPARING THE TURNTABLE We consider that the Outline turntable is properly connected to your PC (refer to 5.5.2 to have details). To prepare for this measurement session you need to: 1) <strong>Manual</strong>ly set the front selector labeled 'Deg Step' to 5°. 2) Rotate counterclockwise the turntable until you reach the desired start position: as we want to start from -60° position it at 300°. 3) Recall the turntable control dialog (Fig.12.9), set Resolution at 5°, Speed at 0.75 RPM and press Link To Measurement Chapter 12 - Waterfall 123
