SAMURAI Software Option by SINUS Messtechnik GmbH

SAMURAI software +  Signal Generator Option + Multi-channel instruments

The SAMURAI Signal Generator Software Option generates a range of signals that may be output by all multi-channel instruments manufactured by SINUS Messtechnik GmbH, including the Soundbook, NoisePAD, Apollo or Apollo Lite Boxes plus laptop, or PCIe Cards plus PC.

The data acquisition instruments and SAMURAI signal generator  option can simultaneously output signals from four independent signal generators whilst simultaneously carrying out acoustic and vibration measurements at the same time using the same multi-channel instrument.

The SAMURAI Signal Generator software option may be used for source excitation for measurement tasks which require particular signal shapes in building acoustics, or may be used to control vibration shakers.


The signals produced by SAMURAI Signal Generator Software Option are provided via the four output channels of the measurement instrument, 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 software option.

Signal shapes include: sine, rectangle, triangle, impulse, multi-sine, logarithmic and linear sine-sweep, as well as pseudo-random noise. Previously recorded WAV files may also be output as signals.

The output channels may also be used to provide a DC representation that is proportional to level values.

The screenshot above shows the generated signals (top LH window), as well as the signal FFT (top RH window) and the resulting application FFT levels shown for two channels in the lower windows.
