Click **View** to open dialog box containing
additional information about the simulation frequencies in your system.
The `Configuration`

block displays the number of
simulation frequencies for a nonlinear model. For linear models, the
actual number of frequencies are automatically optimized during simulation.
Because the solver computes a solution to the network at each simulation
frequency, computation time scales according to the size of this value.

By clicking a listed simulation frequency, you can see which
linear or multiple combinations of fundamental tones represent that
frequency. From the dialog box, you can also plot the simulation frequencies
on a number line.

The block parameters define a set of simulation frequencies
as combinations of fundamental tones: [*m***f*_{1} + *n***f*_{2} +
…]. In this case, represented as [*f*_{1},*f*_{2},…],
and the integers *m* and *n* are
bounded by the corresponding **Harmonic order**, |*m*|
≦ *h*1, |*n*| ≦ *h*_{2},
etc. Only positive frequencies are considered.

For example, suppose that you have a single fundamental tone *f*_{1} =
2 GHz and corresponding harmonic order *h**1* =
3. The set of simulation frequencies [0,
f_{1}, 2f_{1}, 3f_{1}]
= [0GHz, 2 GHz, 4 GHz, 6GHz].

As a second example, suppose you have a circuit with two fundamental
tones [f_{1} = 2 GHz, f_{2} =
50 MHz] and corresponding harmonic orders h_{1} = *h*_{2} =
1. This setup results in five simulation frequencies
with values [0, *f*_{2}, *f*_{1}-*f*_{2}, *f*_{1}, *f*_{1}+*f*_{2}].

The set of simulation frequencies must include all carrier frequencies
specified in the SimRF subsystem such as the carrier frequencies
inside Inport, Outport, and source blocks.
