To 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.

Select 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.

Select the Intermodule menu.

3 Select 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.
