Chapter 3: Using the Logic Analyzer in Timing or State Mode

Cross-Triggering

Cross-Triggering

An instrument must be armed before it can look for a trigger. By default, instruments are set to be armed immediately when you Run the measurement.

However, you can set an analyzer instrument to be armed by another instrument (in a different slot or frame).

“To cross-trigger with another instrument” on page 112

To cross-trigger with another instrument

1.Select the Intermodule button (or from the Window menu pick, select System and Intermodule).

2.In the Intermodule window, select the desired instrument icon and arm it from the Group Run.

3.Select the next instrument icon and arm it from the first instrument.

When the logic analyzer waits for the arm signal (timing or 200 Mb/s state only)

1.In the Trigger tab's Trigger Sequence area, select the sequence level that should wait for the other analyzer's trigger.

2.In the Trigger Functions subtab, select the Wait for arm in trigger function; then, select either the Replace or Insert before button.

(You can also use an advanced trigger function, edit it, and insert an Arm in from IMB event.)

If the trigger sequence does not pass through the level containing the Wait for

 

Arm In event, the logic analyzer will not wait for the arming signal.

 

 

When the logic analyzer waits for the arm signal (400, 800, 1250, or 1500 Mb/s state only)
