Power Sweep with NLAMP

Power Sweep with NLAMP

For the power sweep, the input power pin is swept over the range -20dBm to 60dBm in steps of 2dBm while performing one-tone harmonic balance.

1. Expand the Analyses icon and double-left-click on powersweep.

The powersweep analysis is the one-tone HB analysis with the added sweep of input power, given by project variable pin. Click OK to close the setup dialog.

2. With analysis powersweep still selected, right-click and select Analyze. The analysis runs to completion.

3. Click on the Results icon and double click on powersweep to see the results:

The powersweep plot shows the fundamental (red) and third harmonic (blue) output power plotted vs. input power pin. Here we can see the saturation of the amplifier. In the linear region the fundamental output power has a slope of 1:1 while the third harmonic has a slope of 3:1 vs. the input power. Both axes are in log scale (dBm).
