Setting Up a Frequency Sweep with Linear Network Analysis

Nexxim linear network analysis supports a built-in sweep of frequency. (For DC analysis or transient analysis, no frequency parameters are predefined.) To perform a frequency sweep with linear network analysis, perform the following steps:

1. Under Circuit, select Add Nexxim Solution Setup. Select Linear Network Analysis for the Analysis Type and accept Frequency Domain for the Category. Click Next.
2. The Linear Network Solution Setup dialog box appears.
3. For Linear Network Analysis, the SweepVariables panel has one frequency parameter (Freq). To set up a sweep of frequency, click Add.
4. The Add/Edit Sweep dialog box opens, with the selected frequency shown in the Variable field (which cannot be modified).

Sweep options are:

• Single Value (enter the value and units)
• Linear Step (enter Start, Stop, and Step values and units)
• Linear count (enter Start, Stop, and Count values and units)
• Decade count (enter Start, Stop, and Count values and units)
• Octave count (enter Start, Stop, and Count values and units).

5. Click Add.
6. If desired, add sweeps of local variables using the procedure given under Setting Up a Local Variable on a Component Parameter.
7. Click OK.
8. Complete the setup information (Output Quantities, etc.), then click Finish.
