ADS Terminator component in transient simulation

It seems that the reactive part of TERM component is ignored by ADS in transient simulation.

I simulated a very simple schematic:


the Term component here is a complex load.


However, the simulation result shows that the voltage and current are in-phase to each other, that means the reactive part of terminator is ignored


as can be seen, the magnitude of load voltage is 2.0V, and the magnitude of load current is 0.04A, so the effective load is 50Ω, not (50+j*100)Ω.

So, in order to get reactive phenomenon in transient simulation using ADS, you should explicitly add one of the two reactive components.
