Abstract
A data acquisition system includes an analog to digital converter, a computer processor and a waveform memory in which is stored digital data from the A to D converter corresponding to an input signal. The processor provides a trigger responsive to a characteristic of a frequency component or components of the input signal to cause the memory to save the waveform data in the memory. The frequency characteristic may be determined, for example, by carrying out a synchronized recursive discrete Fourier transform which is updated for the selected frequency component or components with each new sample from the A to D converter.
