The voltage excitation signal will be recorded during the solver run.Ĭurrent: This port type realizes a current source, exciting with a constant current amplitude. In case that this port is not stimulated in the analysis the voltage along the wire is set to zero. Voltage: This port type realizes a voltage source, exciting with a constant voltage amplitude. An equivalent circuit diagram for a discrete face port of the S-parameter type is shown below. Note that the orientation of the discrete face port is used to determine the phase of the S-parameters. In addition it is also possible to monitor the voltage across and the current through the discrete face port. This port realizes an input power of 1W and enables the calculation of correspondent S-parameter. The current source will only be active, when the discrete element is the stimulation port in the analysis. S-Parameter: This port type is modeled by a lumped element, consisting of a current source with an inner impedance, which excites and absorbs power. Please note, that the input signal for the port is normalized differently, depending on the chosen port type. Corresponding to this setting the input parameters in the properties frame will change. Port type: Select here the type of the discrete face port. Please refer to the Discrete Port Overview page to find some more detailed information especially regarding the construction procedure. Two different types of discrete face ports are available, considering the excitation as a voltage or as an impedance element which also absorbs some power and enables S-parameter calculation. The discrete face port is replaced by a Discrete Edge Port if any other solver is chosen. It is supported by the integral equation solver, the transient solver, as well as the frequency domain solver with tetrahedral mesh. The discrete face port is one kind of discrete port.
