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...

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...
