Adaptive Sweep

Hi!

I have been using ADS Momentum for some time now and there is a behavior of the software that drives me nuts.

I am using Adaptive Sweep and for rather large structures momentum for some reason uses lots and lots of its adaptive points in a small interval around 19 MHz. Sometimes almost half of the frequency points are in this small interval (+/-1 MHz) even though the complete interval is 0 GHz to 50 GHz.

I assume that this has something to do with DC(?) convergence? I have tried to combine adaptive sweep with other types (linear) but then runs into another problem where the interpolation between simulation points is extremely strange (passes through center of smith chart).

Any ideas?
