Abstract:
A data acquisition device incorporates a front end analog-to-digital converter (ADC), which is responsive to an applied analog input signal, sample that signal and provide digital data representative of the sampled signal. The digital data is applied to a data channel connected to a data acquisition memory, which stores data values representative of the sampled analog input signal. The digital data from the ADC is also applied to a real time a trigger channel connected to a composite function trigger equalizer and filter, a trigger processor and to a trigger memory. The trigger channel operates in real time to identify trigger events and store real-time trigger event occurrence signals in the trigger memory. A controller reads out the stored data values from the data acquisition memory by way of a data equalizer, in synchronism with corresponding real-time trigger event occurrence signals from the trigger memory.
