Hello all,
I have to check Coaxial cable emission which is connected to a housing. N1 to N2 coaxial cable and single wire from N3 to N4 and N5 to N6. N1, N2, N4, N5 and N6 are "Connected to 3D". After modeling the block mentioned in screenshot. The schematic is obtained as in the next screenshot attached. In the simulation I have provided Pulse signal and did transient analysis, there is no error. When I go for 3D microwave studio it is asking for set excitation. As I have already provided pulse to the port in the simulation module. Why I need to set excitation again in 3D microwave studio? Is there a option to connect the simulation module signal excitation to 3D microwave studio excitation?
