About S-Parameter Simulation

Using the S-parameter simulation controller (S-Parameters) from the Simulation-S_Param palette enables you to:

• Obtain the scattering parameters (S-parameters) of a component, circuit, or subnetwork and convert those parameters to Y- or Z-parameters.
• Plot, for example, the variations in swept-frequency S-parameters with respect to another changing variable.
• Simulate group delay or linear noise.
• Simulate the effects of frequency conversion on small-signal S-parameters in a circuit employing a mixer. (This is also known as analyzing a frequency-translating network.)

The Simulation-S_Param palette also contains components for general simulation options and sweeps, as well as a variety of measurement components for calculating relevant measurements. See the following topics for details on S-parameter simulation:

• Performing an S-Parameter Simulation has the minimum setup requirements for an S-parameter simulation.
