Architecture of a modern signal processing oscilloscope

For many applications the functions of a voltmeter, counter, power meter, etc, can be provided by a single measurement instrument, the digitizing processing oscilloscope. An instrument featuring these capabilities has to be designed with respect to high-speed data transfers and simultaneous calculation of processed waveforms as well as scalar measurement functions. This paper describes the architecture of a recently introduced modern processing oscilloscope which is able to perform algebraic and analytical processing on time domain signals as well as various amplitude or time measurements.
