80.0 CLIO dBSPL 70.0 60.0 50.0 40.0 30.0 100 1k Hz 10k 20k Figure 9.6 9.7 TIME DATA DISPLAY (OSCILLOSCOPE) The time data (Fig. 9.7) is an ancillary display to an FFT or RTA executed measurement. Here we see a 100Hz sinusoid captured and analyzed with a 16K FFT. Figure 9.7 The time data display has a number of particular features that allow, out of user control, for automatic scale adjustment and triggering of the displayed signal. The time information displayed is the processed data only. The user can zoom in and out of this data but it is not possible to display more than one acquisition area. Fig. 9.8 shows this effect; the same 100Hz sinusoid as before seems now truncated; this means that we only reached the maximum displayable data, in case of a 16K FFT @ 51200Hz sampling this is exactly 320ms. 102 Chapter 9 - FFT
Figure 9.8 9.8 FFT AND MULTI-METER There is a close interaction between FFT and Multi-meter operations. The two measurements share the same acquisition and processing core. Should they operate together the FFT control panel acts as the master while Multi-meter follows as the slave. In this situation, among other peculiarities, the Go and Stop buttons of the Multimeter are disabled; if an FFT acquisition is started then the Multi-meter runs as well, the same when you stop the measurement. More on this is in section 8.6. 9.9 FFT AND Leq ANALIZER It is possible to execute FFT or RTA analysis while an Leq measurement is taking place. The following figure shows the analysis of a sample of speech done with Leq and RTA in parallel. Some limitations apply to FFT settings, in particular it is not possible to select an FFT size higher than 32768. See also chapter 16. Chapter 9 - FFT 103
