Abstract:
An apparatus for capturing and digitizing at least one analog signal derived from an event with a signal duration that is short compared to the interval between consecutive events, comprising:two or more memories, each capable of storing a sequence of analog samples from one of two or more analog signals derived from the event; a trigger for triggering the sampling and storage in the two or more memories of a sequence of analog samples to occur at about a 0.5 gigahertz or higher sampling rate; means communicating with the memories for selectively initiating the read out of the analog samples in the memories; an analog to digital converter for receiving each analog sample read out from each of memories and producing from the analog samples corresponding digitized sample values; a digital signal processor for operably controlling parameters of the analog to digital converter and receiving the digitized sample values; and an output stage under control of the digital signal processor for outputting the digitized sample values, such that the receiving and conversion and the output of digitized sample values are completed during the interval between consecutive events.
