Comparative measurements between a digital acquisition system and an analog acquisition system, namely Siemens SCADAS.

The dataset includes calibration measurements, background noise measurements, brand new radial bearing measurements. The measurements on the brand-new radial bearing were taken on a motor test bench at 15 Hz and at 25 Hz measurements.

Each file contains a mono track at fs = 48 kHz for the digital acquisition system and fs = 51.2 kHz for the analog acquisition system.

The measurements were taken using the same sensor, a top-quality laboratory-grade piezoelectric accelerometer, PCB Piezotronics 353B18, having a full-scale of +/- 500 g and 10.4 mV/g sensitivity.
