Intermodule Measurements

To view trace lists and waveforms together on the same display

To view trace lists and waveforms together on the same display

1Set up the modules whose data you wish to view as part of a group run.

You won’t need to do this if the two measurement modules for which you want mixed display are really part of the same module. For example, you might have an HP 16550A state/timing analyzer configured as two separate analyzers, one a state analyzer, the other a timing analyzer. You can use mixed display to view the timing analyzer waveform with the trace lists from the state analyzer.

2Select the module for which you wish to show waveforms.

This might be an oscilloscope module or a timing analyzer.

3Select the label field to the left of the waveform display area twice, then choose the waveforms to be shown.

When you double-select the label field to the left of the waveform display area, a new menu appears that allows you to insert and delete signals and choose the relative display size and position for the signals.

4Select the state analyzer.

5Set the Trigger menu of the state analyzer and set the Count field to Time.

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 manual for your logic state analyzer for details on how to count time with the analyzer.

6To insert state listings, select any label field from the state listing. From the popup that appears, select the desired label to insert.

7Select Mixed Display from the menu field.

8Select Group Run from the upper right corner of the display.

You can position X and O Time markers on the waveform display, if desired. Once set, the time markers will be displayed in both the listing and the waveform display areas. Note that even if you set X and O Time markers in another display, you must also set the Time markers in the Mixed Display if Time markers are desired.
