Microstar Laboratories (Bellevue, WA) has announced the release of the Rotating Machinery Analysis module with software tools to facilitate mixed time measurements and rotation measurements of rotating machinery. The software enables time-based sampling or encoder-based sampling, or both at the same time. The module processes data captured by a fixed-rate, high-resolution sampling clock with software processing operating at continuously varying rates aligned to pulses from the encoder device. The processing uses DSP technology based on classical sampling theory.Users can observe and record instantaneous speed at each index pulse position. At these locations, users can trigger the capture of a block of encoder-based data, and also trigger the capture of a block of fixed-time data. The module also can generate profiles of speed and acceleration at each sampling location. The company’s xDAP Data Acquisition Processor device provides the operating environment to support the module. The xDAP 7420 can support continuous operation at up to 1 million 16-bit samples per second per channel on 8 channels simultaneously.
