Arming and Additional Instruments
Occasionally you may need to start the analyzer acquiring data when
another instrument detects a problem. Or, you may want to have the
analyzer itself arm another measuring tool. This is accomplished from
the Arming Control field of the Analyzer Trigger menu.

To arm another instrument

1Attach a BNC cable from the External Trigger Output port on the
back of the logic analyzer to the instrument you want to trigger.
The External Trigger Output port is also referred to as "Port Out." It
uses standard TTL logic signal levels, and will generate a rising edge
when trigger conditions are met.
2In the Analyzer Trigger menu, select Arming Control.
Arming Control is below the Run button.
3Select the field near Arm Out, and choose PORT OUT.
4If you are using both analyzers, set the Arm Out Sent From field
in the upper right corner.
This field does not appear if only one analyzer is configured.
The selected analyzer will send the arm signal when it finds its trigger.
5Select Done.
When you make a measurement, the analyzer will send an arm signal
through the External Trigger Output when the analyzer finds its
trigger.
