<analog.acsweepsimulation />

<analog.acsweepsimulation /> runs small-signal AC analysis over a frequency range. Import analog from "tscircuit". Set the source's acMagnitude (and optionally acPhase) to define its AC excitation; voltage sets its DC bias. The equal-resistor divider below has a constant voltage ratio of one half.

import { analog } from "tscircuit"

Properties

Property	Description
`sweepType`	Required frequency spacing: `"linear"`, `"decade"`, or `"octave"`.
`startFrequency`	Required positive starting frequency. Numbers are hertz.
`stopFrequency`	Required ending frequency, greater than `startFrequency`.
`samplesPerInterval`	Required positive integer samples per decade or octave. Omit for linear sweeps.
`sampleCount`	Required positive integer total samples for linear sweeps. Omit for decade and octave sweeps.
`name`	Optional experiment name. Use a unique name for each experiment.
`spiceEngine`	Engine to run the analysis, such as `"ngspice"`. Defaults to `"spicey"`; the selected engine must support the analysis.
`spiceOptions`	Solver options: `method` (`"trap"` or `"gear"`), `reltol`, `abstol`, and `vntol`.
`graphIndependentAxes`	Give each probe channel an independent vertical scale.
`children`	An optional `<analog.sweepparameter />` for repeated runs.

For example, a linear sweep uses sweepType="linear" and sampleCount={100} in place of samplesPerInterval. Add voltage probes or ammeters to obtain magnitude and phase results.
