Abstract
We describe a prototype digital device for measuring high-order struct ure functions in turbulence. Because the structure function is a speci al case of the correlation function, the device may find usage outside the study of turbulence. The device operates at 20 kHz on 12-bits dat a and updates probability distribution functions of signal differences for 64 arbitrarily chosen time delays in real time.
