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...
Calibrating with broadband noise provides a convenient way to determine the complete amplitude, frequency and phase response of an instrument in a single experiment. The Güralp DM24 digitiser includes a pseudo-random number generator and 20-bit DAC which can be used to generate broadband noise with a flat frequency profile throughout the passband of the instrument. An extension to Scream allows the user to analyse and plot the results. Read more...
