Example of P2D Simulation

This example simulates an amplifier, sweeping input power over various levels. Setup for P2D simulation illustrates the setup for simulating a simple amplifier.

Setup for P2D simulation

1. From the Simulation-LSSP palette, select an P2D simulation component, place it on the schematic, and double-click to edit it.
2. Select the Frequency tab. In the P2D file to output field, enter a name for the .p2d file. This is the file that will be generated by the simulation. The filename must be in quotes. The default filename is "default.p2d" .
3. In the Order field, accept the default value of 3 or edit this value.
4. Select a sweep type and values for Start , Stop , and Step-size as desired. Optionally, you can select a sweep plan.
5. Select the Power tab and select a sweep type, as well as values for Start , Stop , and Step-size as desired. Optionally, you can select a sweep plan. Power is in dBm.

   Note The Krylov option should not be selected for one-tone problems such as this, especially when they involve sweeping.

6. Simulate . The result is a .p2d file that can be used in subsequent simulations.
   Note that with these power sweep settings, gain compression will occur in the amplifier. You can see this if you set up and run this simulation, then plot the results HB.S(2,1) on a rectangular plot. You can view the .p2d file with any ASCII text editor. A portion of the file from the example is shown here.
