== Nodal Analysis of RF Circuits ==
The simplest RF circuit analysis type in [[RF.SpiceA/D]] is the "AC Frequency Sweep" Test. As mentioned earlier, this is identical to the AC frequency sweep test of [[B2RF.Spice A/D]]. The only difference here is that the frequency-domain models of [[Multiport Networks|multiport networks]] and transmission line segments or components are added to the analog or mixed-mode simulation of your circuit. Just as in [[B2RF.Spice A/D]], the AC Test is run from the Test Panel of the Toolbox.
