SAMURAI Option
Overview
Field of Application:
This option provides four independently operating signal generators, which can produce various shapes of signals.
The option is applied for measurement tasks which require particular signal shapes (e.g. building acoustics or the control of shakers).
Description:
The signals produced by the generators are provided via the four output channels of the measurement hardware as electrical signals in the range of ± 3.16 V. Pink and white noise (full bandwidth or band-limited) as well as sine-sweep (for reverberation time measurements) are provided in the SAMURAI basis functionality.
This option includes the signal shapes: sine, rectangle, triangle, impulse, multi-sine, logarithmic and linear sine-sweep as well as pseudo-random noise. Furthermore, .WAV files may also be output.
It is also possible to use the output channels to provide a DC representation of the level values.
A graphical preview shows the signals as well as the signal FFT resulting with the application of various FFT windows. The preview allows the effects of the FFT window to be assessed.
