Small-Signal Analysis, Frequency Domain
The Small-Signal Analysis, Frequency Domain () study is used for studying small oscillations about a biased solution in electromagnetics.
The study consists of two study steps: a Stationary study step, for computing the biased solution, followed by a Frequency-Domain Perturbation study step, for computing the frequency response about the biased solution. For the second study step, the computation is for a linear perturbation about the biased solution.

To add harmonic perturbation, see Harmonic Perturbation — Exclusive and Contributing Nodes. See also linper for information about the linper operator for indicating load terms that should be used by stationary solvers setting for harmonic linear perturbation.
For information about plotting results from this type of models, see Small-Signal Analysis, Prestressed Analysis, and Harmonic Perturbation Plot Settings.
