Abstract
A method and apparatus for synchronizing presentation of multi-domain measurements using actual or quasi 3-D representation. The synchronization between data streams acquired in different measurement domains is performed by using timestamps, a common trigger event, or a common clock, or a combination of any or all of them. In this way, for example, a transient anomaly in the RF spectrum of a communications signal may be correlated with, and displayed with, a related corrupted data communications packet.
Claims21
A method, comprising, the steps of:
- receiving a plurality of sample streams representing respective signal measurements made in differing measurement domains;
- temporally-aligning said sample streams;
- generating waveform data associated with said temporally aligned sample streams, said waveform data representing sample magnitudes as a function of time and including Z-axis information adapted to illustrate at least one inter-stream timing relationship;
- and
- displaying said waveform data on a display screen.

- generating waveform data associated with said temporally aligned sample streams, said waveform data representing sample magnitudes as a function of time and including Z-axis information adapted to illustrate at least one inter-stream timing relationship;
- wherein said plurality of sample streams represent an oscilloscope graph, a logic analysis trace, a racket representation and a frequency spectrum waterfall;
- and
- wherein said waveform data is produced in a display in which a first axis is time, a second axis is measurement domain and a third axis is content of a measured phenomenon.
