●GENERAL DESCRIPTION
●The ADIS16228 iSensor® is a complete vibration sensing system that combines triaxial acceleration sensing with advanced time domain and frequency domain signal processing. Time domain signal processing includes a programmable decimation filter and selectable windowing function. Frequency domain processing includes a 512-point, real-valued FFT for each axis, along with FFT averaging, which reduces the noise floor variation for finer resolution. The 14-record FFT storage system offers users the ability to track changes over time and capture FFTs with multiple decimation filter settings.
