The Brookhaven Instruments BI-9000AT Digital Correlator has an adjustable delay range capable of producing a contiguous correlation function from 25 ns to 1,310 s representing a time axis that spans more than 10 decades in the standard configuration. The middle and low speed circuits can be operated as independent correlators, simultaneously processing different input signals. This can be used, for example, to correlate two light scattering signals from different detector angles simultaneously. Or, for crosscorrelating two signals originating from two different positions in a liquid. An on-board microprocessor on each correlator card controls the circuits and collects the correlation function(s). This relieves the CPU of the host computer of many tasks and allows up to eight correlator cards to be run simultaneously in a single computer. And, unlike other correlators, the BI-9000AT requires no prescaling. The BI-9000AT digital correlator can be used for real-time operation in both auto- and cross-correlation modes. It is 100% efficient in either mode over the entire delay time range.
