Used to generate and configure up to 6 fixed sinus. A sinusoidal signal is generated with the frequency specified in the sine '''Frequency''' field. The frequency corresponds to one of the analysis bands. This type of signal is used for measuring the amount of distortion in a system, for example. The amplitude of the signal can be changed using the '''Level''' settings. | Used to generate and configure up to 6 fixed sinus.

[[Image:Reports_Tools_Ribbons_347.png]]: Multi-sine: Opens the ''Multi-sine'' properties dialog for adjustment. | |||
Multisine is computed by adding sine signals whose frequencies are power of two sub-modules of sampling frequency. This means that multisine output block includes all discrete sine waves of FFT spectrum of corresponding block size and resolution. Multisine has the advantage of showing no leakage effect in FFT as all sine waves are exact periods of the trigger block for FFT computation. The most appropriate FFT weighting window to be used is “uniform” window. Multisine generators work on a sample block basis, it means signal blocks are repeated identically over time. | Multisine is computed by adding sine signals whose frequencies are power of two sub-modules of sampling frequency.
