  • Method and apparatus providing concatenated data from multiple signal acquisition devices
    Patent number: 7065458
    Abstract: A system includes a plurality of digital storage oscilloscopes (DSOs) in which each DSO requires a respective temporal portion of a signal under test (SUT) according to a synchronized triggering signal and respective post-trigger count periods such that a plurality of acquisition records may be concatenated to produce a longer acquisition record.
    Type: Grant
    Filed: December 17, 2002
    Date of Patent: June 20, 2006
    Assignee: Tektronix, Inc.
    Inventors: Que Thuy Tran, David L. Kelly, Douglas A. Blegen
  • Method and apparatus providing interleaved data from multiple signal acquisition devices
    Patent number: 6832174
    Abstract: A system comprising a plurality of digital storage oscilloscopes (DSOs) in which each DSO acquires a common signal under test (SUT) according to respective clock signals having common frequency parameters and respective phase parameters such that a plurality of acquisition records may be interleaved to produce a higher effective resolution acquisition record.
    Type: Grant
