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 16-record FFT storage system offers users the ability to track changes over time and to capture FFTs with multiple decimation filter settings. The 22 k Hz sensor resonance and 100.2 k SPS sample rate provide a frequency response that is suitable for machine-health applications. The aluminum core provides excellent mechanical coupling to the MEMS acceleration sensors. An internal clock drives the data sampling and...
