Fast Sweep Options

Generates a unique full-field solution for each division within a frequency range. Best for models that will abruptly resonate or change operation in the frequency band. A Fast sweep will obtain an accurate representation of the behavior near the resonance. Fast sweeps are disabled if an anisotropic boundary condition is present.

Discrete Sweep Options

Generates field solutions at specific frequency points in a frequency range. Best when only a few frequency points are necessary to accurately represent the results in a frequency range.

Interpolating Sweep Options

(default)

Estimates a solution for an entire frequency range. Best when the frequency range is wide and the frequency response is smooth, or if the memory requirements of a Fast sweep exceed your resources.

All discrete basis solutions are solved prior to interpolating sweeps because it is possible that an interpolating sweep can re-use already solved frequencies from a discrete sweep.

For Time Domain Reflectometry plots (TDR), you must use an interpolating sweep.

When you select Interpolating sweeps in the Edit Sweep dialog, the Interpolation options tab is activated. This lets you specify a maximum number of solutions, and other interpolation values.
