To Receive An Arm Signal From Another Instrument - HP 1660CS-Series User Manual

To receive an arm signal from another instrument

When you set the analyzer to wait for an arm signal, it does not react to data
that would normally trigger it until after it has received the arm signal. The
arm signal can be sent to any of the Trigger Sequence levels, but will go to
level 1 unless you change it. Setting up the analyzer to receive an arm signal
is more efficient when the sequence levels are already in place.
Connect a BNC cable from the instrument which will be sending the
1
signal to the External Trigger Input port on the back of the logic
analyzer.
