# What exactly are terms in ADS? [closed]

I have been using them to simulate my s-parameter tests, but I'm not sure what they are exactly. Are they simply some impedance that simulates an infinite transmission line?

They might also (I don't remember this detail) also be used to generate stimulus signals for S-parameter simulations, (For example, so you not only get the $S_{21}$ but also get $S_{12}$) but if you want this behavior it would be more clear to use a Port device than a Term.
