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.
Claims12
A test and measurement system, comprising:
- a plurality of digital storage oscilloscopes (DSOs), each of said DSOs acquiring a common signal under test (SUT);
- each of said DSOs acquiring said common SUT in response to a common trigger signal, common clock signals and respective post-trigger delays;
- said post-trigger delays adapted to provide a respective plurality of samples from each DSO during respective time periods;
- said sample streams being merged to produce a combined sample stream.

A method adapted for use in a system comprising N digital storage oscilloscopes (DSOs) where N is an integer greater than one, said method comprising:
- receiving at each of said N DSOs at least one common signal under test (SUT);
- digitizing said at least one common signal under test (SUT) using a respective phase staggered analog to digital (A/D) converter within each DSO to produce N streams of samples in response to detection of a combined trigger event;
- and
- concatenating a temporally distinct sample stream portion from each of said N sample streams to produce a combined sample stream.
