  • Digital oscilloscope comprising multiple data acquisition pathways
    Patent number: 9804200
    Abstract: A digital oscilloscope comprises a sampling unit configured to sample an input signal received from an oscilloscope probe to produce a first stream of digital samples, a first acquisition system configured to store and process the stream of digital samples to produce a first data set, a second acquisition system configured to store and process the first stream of digital samples independent of the first acquisition system to produce a second data set, and a display system configured to concurrently display the first data set in a first format and the second data set in a second format different from the first format.
    Type: Grant

  • METHOD AND APPARATUS FOR EXTRACTION OF BASEBAND WAVEFORM FROM AMPLITUDE MODULATED SIGNAL VIA TIME DOMAIN SAMPLING
    Publication number: 20170012807
    Abstract: A measurement apparatus, for example a digital oscilloscope, receives an amplitude modulated (AM) signal comprising a baseband signal, having a baseband waveform, modulating a carrier signal, and reconstructs the baseband waveform. The measurement apparatus: samples the AM signal at a sampling rate which produces a plurality of data samples for each period of the carrier signal; determines the amplitude of the baseband signal for each of a plurality of periods of the carrier signal from at least some of the plurality of data samples for each period; and reconstructs the baseband waveform from the amplitudes of the baseband signal for each of the plurality of periods of the carrier signal. The measurement apparatus may display the reconstructed baseband waveform on a display device.
