How to Excite an SMA port in HFSS?

Does anyone knows how to excite an SMA port in HFSS V17, i'm using the 3D Model. I tried to use a lumped port in the pin but it doesn't worked. Anyone has any idea?
Thanks!

for lumped port exciation draw a circle at the end of the SMA connector covering the outer conductor.....then apply the lumped port excitation to that circle.

It says Port '1': The port has no terminals defined on it.

Thanks

Sounds correct, for a driven modal setup. What exactly is not working?
