The VSA-1225 vibration spectrum analyzer (VSA) is a PDA-based vibration analyzer-data collector. It’s on the Windows Mobile/Pocket PC platform. It includes version 1.8 of the company’s Spectrum software suite. The analyzer allows users to utilize vibration analysis in machine condition monitoring, predictive maintenance, and routine troubleshooting. The VSA-1225 consists of hardware and software, plus the Hewlett-Packard iPAQ handheld computer, and one or more sensors. For the handheld computer, the Spectrum software suite includes the manufacturer’s Spectrum and Review software. Version 1.8 of the Spectrum software records and shows vibration FFT spectra in acceleration, velocity, and displacement displays, and now in a new vibration decibel display. In addition, Spectrum provides time-domain acceleration waveforms, and records and displays overall vibration with color-coded ISO (or custom) alert levels. Using the Review software, the customer can compare previous reads with the current read in Spectrum. The VSA module includes an extremely low-noise analog input for standard ICP®-type accelerometers and velocity sensors, optimized digital circuitry, and a built-in rechargeable lithium-ion battery with optimized power management.
