Abstract
A primary test and measurement device merges a primary (i.e., local) a non-primary (i.e., remote) waveform data to produce a display signal that, when presented on a display device, shows both waveforms. The primary measuring device may utilize respective transparent windows for each waveform such that the transparent windows may be overlaid during presentation to display waveform data from the non-primary measuring devices upon the primary measuring device. In this manner, a plurality of test and measurement devices are used to provide a single combined image for presentation.
Claims21
A method for use in a test and measurement instrument, comprising:
- associating, with a first display window, first waveform data derived from a locally acquired signal under test (SUT);
- associating, with a second display window, second waveform data derived from a remotely acquired SUT, said second display window having a transparent background display property;
- generating an image signal adapted for use by a display device to produce imagery comprising said second display window superimposed over said first display window.
A test and measurement system, comprising:
- a first signal acquisition device comprising a signal acquisition module and a communications module, said signal acquisition module acquiring at least a first signal under test (SUT), said communications module providing waveform representative data of said acquired first SUT to a communications link;
- and
- a second signal acquisition device comprising a signal acquisition module, a communications module and a display module, said signal acquisition module acquiring at least a second SUT, said communications module receiving said waveform representative data of said acquired first SUT from said communications link, and said display module generating a display signal including waveform representative data of said at least first acquired SUT and said at least second acquired SUT.
A test and measurement instrument, comprising:
- an acquisition module, for acquiring a first signal under test (SUT) to produce a first sample stream;
- a processing module, for modifying at least one of a timing parameter and an amplitude parameter associated with said first sample stream to produce waveform representative data of said first sample stream;
- a communications module, for receiving waveform representative data of a second sample stream from a communications link;
- and
- a display module, for generating a display signal that, when displayed on a display device, produces imagery including superimposed waveforms of said first and second sample streams.
