M+P and VTI Instruments have collaborated to deliver dynamic signal analysis (DSA) instrumentation for NASA Plum Brook's Reverberant Acoustic Test Facility (RATF), housing a space simulation chamber.
RATF houses the world's largest Space Environment Simulation Chamber and will use VTI's VT1432B digitiser plus DSP, along with integrated arbitrary waveform generation (ARB) capability, as part of M+P's Digital Acoustic Control System (DACS).
The DACS will be used to configure and control servo-hydraulic and electromagnetic modulators, and to acquire data from up to 24 individual microphones.
Scalable onboard DSPs, multi-channel independent 24-bit digitisers and comprehensive transducer-signal conditioning ensure high-precision, gap-free data.
VTI's DSA solutions are suitable for addressing a wide range of acoustic control and test, machine-condition monitoring, NVH (noise, vibration and harshness), rotating machinery, structural test, vibration control and modal test applications.
