16.3 Leq SETTINGS Time resolution Selects the time resolution of the measurement. It is possible to choose a value among 1s, 1/2s, 1/4s, 1/10s, 1/100s and 1/1000s. Normally choose the least resolution possible as this choice directly reflects on the measured data size (.leq binary files). This setting is not influencing the sampling frequency that remains 48000Hz. Frequency weighting Selects the frequency weighting applied; you can choose either No Weight or A- Weighting. Peak mode Selects how the peak is measured. You may select between the two: - Max. The peak is the maximum value acquired given the particular time resolution and frequency weighting. - LUser.The peak is the maximum value of the LUser measurement. Capture time data to disk If active, during the measurement the acquired time data is saved to the hard disk. It is then possible to create a standard wave file of the event measured for later post processing. Be extremely careful when activating this feature as it requires a huge amount of disk space: circa 6MB/min or 0.35GB/hour. Maximum recordable time is 12 hours. LUser integration Selects the time integration of the user definable level measurement. You may choose among the following: - No. No integration is applied; the result is that the classical time history is displayed. - Impulse. Classical Impulse integration, 35ms time constant with 2.9dB/s decay rate. - 35ms. Modified impulse integration; only 35ms time constant. 188 Chapter 16 - Leq Level Analysis
17 WOW AND FLUTTER 17.1 INTRODUCTION Within this menu Wow & Flutter measurements are possible, meeting both IEC and NAB standards. Basically, what is measured is the frequency modulation that follows instantaneous speed variations due to mechanical imperfections in analog recording or playback devices. Differently than in traditional Wow & Flutter analyser the whole measuring process is taken digitally without relying on analog FM discriminator, filter and detector with much higher accuracy, limited by the clock quartz only. Furthermore, aside traditional number data, a time graph is presented as well as a Frequency Domain Analysis of the demodulated signal. The latter feature greatly simplify locating the cause of problems, once rotating speed and mechanical circumference of eventually defective rotating parts are known. Carrier frequency can range form 1500Hz to 6000Hz. This is important if you record directly the test signal. Using existing test support, IEC specify a test frequency of 3150Hz, NAB of 3000Hz. 17.2 WOW & FLUTTER CONTROL PANEL 17.2.1 TOOLBAR BUTTON Starts a Wow & Flutter analysis. Figure 17.1 Enables weighting filter in the time domain windows. Frequency Domain remains unaffected. Works both when the analysis is running or as a post process. Switch to Time Domain.
