Guralp digitisers provide calibration signal generators to help you set up your sensors. Calibration is most easily done through a PC running Guralp’s Scream! software, but you can also do it using a handheld control unit (HCU) and an oscilloscope. Depending on the digitiser type, sine-wave, step and broadband noise signal generators may be available. In this article, we will use a sinusoidal input signal to determine the sensor response at a single frequency of interest. Read more...
