Signal analyzer software upgrade

To speed up noise and vibration data analysis for vehicle manufacturers and industrial machinery, Brüel & Kjær (Norcross, GA) offers RT Pro 7.3 enhanced software for its Photon signal analyzer. The RT Pro 7.3 release provides enhanced Fast Fourier Transformation, signal analysis, 1/nth octave/acoustic analysis, modal data acquisition and swept sine measurements, making it suitable for testing acoustic and vibration in applications such as rotating machinery and automated production lines. Powered via a USB 2.0 port and weighing less than 227 g (8 oz), the PHOTON+ unit operates on a notebook PC battery. It has been designed specifically to turn any PC into an instrument-quality portable analyzer that provides instant multi-channel noise and vibration results, as well as onsite data verification.
