Intermodule Measurements

To see time correlation of each module within an intermodule measurementTo see time correlation of each module within an intermodule measurement

Time correlation in the intermodule menu can help you see when the trigger occurred for each module and the relative time range of data captured by that module.

1Select Time in the Count field of the trigger menu of each logic state analyzer whose measurement will be time-correlated with the other modules.

Timing analyzers and digitizing oscilloscopes implicitly count time because their sampling is driven by an internal clock, rather than an external state clock. See the User’s Reference for your logic state analyzer for details on how to count time with the analyzer.

2Select the Intermodule menu.

3Select the Group Run field in the upper right hand corner.

Once the measurement has started, view the time correlation bars at the bottom of the Intermodule Menu. The “T” in each bar indicates the relative time at which that module found its trigger condition. The yellow portion of each bar indicates the start and stop points of the acquisition window of the associated module relative to the other modules in the measurement.
