460 -Sensor calibration allows user to input an electrical test signal into a connected sensor to simulate ground motion. The resulting digitized sensor output can then be analysed to assess various attributes of the sensor, such as basic functionality,
461 -frequency response and/or sensitivity stability over time. For a high-quality broadband sensor, these parameters typically remain stable over time, so that if the sensor initially meets manufacturer’s specifications and has not suffered damage,

471 471  The Centaur data recorder can generate and output an analog signal using a 16-bit internal digital-to analog converter (DAC). The DAC output is applied to the sensor for calibration purposes via the matching sensor cable. Make sure to use manufacturer cables as the correct signal lines have been connected to the correct pins of the mating connector. The Centaur CTR, CTR2 and CTR3 series models may generate signals of up to ±5 V amplitude, while the Centaur CTR4 series models have an enhanced calibration output.
472 472  
473 473  Calibration output signal actions are launched from the Waveform page in the Centaur Web interface. A synthetic waveform signal generator allows you to generate sinewave and pseudo-random binary (PRB) signals on demand. User can configure the sine frequency or PRB pulse width, signal duration and amplitude as well as specify lead-in and lead-out silence intervals before and after the calibration waveform. One can also select and play a calibration file containing any other desired digital time series waveform that by uploading it to the Centaur, such as a swept sinewave, step function, random noise, or chained PRB sequence.
