Connection port for RF subsystem
The Connection Port block, placed inside a subsystem composed of SimRF™ Equivalent Baseband blocks, creates an open round physical modeling connector port on the boundary of the subsystem. When it is connected to a connection line, the port becomes solid .
You connect individual blocks and subsystems made of SimRF Equivalent Baseband blocks to one another with connection lines instead of normal Simulink® signal lines. These blocks and subsystems are anchored at the open, round physical modeling connector ports . Subsystems constructed out of SimRF Equivalent Baseband blocks automatically have such open round physical modeling connector ports. You can add additional connector ports by adding Connection Port blocks to your subsystem.
This field labels the subsystem connector port created by this block. Multiple connector ports on the boundary of a single subsystem require different numbers as labels. The default value for the first port is 1.
Use this parameter to choose on which side of the parent subsystem boundary the Port is placed. The choices are Left or Right. The default choice is Left.
