12.2 WATERFALL AND DIRECTIVITY CONTROL PANEL Fig 12.1 and 12.2 show the Waterfall and Directivity control panel in many of its possible configurations; as you may imagine the post processing capabilities of this menu are very powerful. It is important to understand which is the source of data for the waterfall and directivity analysis. Waterfall A waterfall analysis is a post process applied to a measured impulse response. Please refer to chapter 10 (MLS&LogChirp) to have details on how to measure an impulse response. Directivity A directivity analysis is a post process applied to a set of measured frequency responses. Please refer to chapters 9,10 and 11(FFT, MLS&LogChirp and Sinusoidal) to have details on how to measure a frequency response. 12.2.1 COMMON TOOLBAR BUTTONS AND DROP DOWN LISTS Starts a waterfall or directivity calculation. Analysis drop down Selects either Waterfall or Directivity analysis. If pressed the waterfall spectra will be referenced to the rearmost one; the directivity spectra will be referenced to the one identified by the Z-Ref value (see 12.5.1) Smoothing drop down Selects the smoothing factor in fractions of octave. Enters the settings dialog. See 12.3.1 and 12.5.1. Displays a color map instead of 3D plot. Interpolates colors in order to obtain smooth level contours. Moves the plot up. Moves the plot down. Expands the plot changing its Y scale. The Y range is reduced. Compresses the plot changing its Y scale. The Y range is increased. 144 Chapter 12 - Waterfall and Directivity
12.3 WATERFALL SPECIFIC CONTROLS When pressed the waterfall plot is displayed. When pressed the impulse response loaded in memory is displayed. Loads an impulse response from disk (from MLS binary files). Takes current MLS impulse response for waterfall calculation. Enters the Marker mode (see Fig. 12.5). In this operating mode it is possible to inspect the single data points of each waterfall slice by clicking and dragging the mouse. When in marker mode, moves the selected waterfall slice backwards. The same action is obtained with the Up-Arrow keyboard shortcut. When in marker mode, moves the selected waterfall slice frontwards. The same action is obtained with the Down-Arrow keyboard shortcut. 12.3.1 WATERFALL SETTINGS Start Frequency Selects the start frequency for the analysis. Stop Frequency Selects the stop frequency for the analysis. Number of Spectra Selects the number of data slices to display. Time Shift (ms) Selects the time between two consecutive spectra. Window Rise Time (ms) Selects the rise time of the data selecting window. Valid only for CSD. Energy Time Frequency (ETF) Selects ETF mode waterfalls. Chapter 12 - Waterfall and Directivity 145
