This test bench project shows a one tone swept frequency test bench for power amplifiers at a constant output power. An extra schematic is added to help determine which output powers are possible.

# This test bench includes:

## Schematics:

**PA_One_Tone_Sweep_Freq**- shows the swept power result at each frequency to see which output powers are possible at each frequency, used to set the CONSTPOUT block.*_*Constant_Power

**PA_One_Tone_Sweep_Freq**- the test bench setup. Includes notes on where to change settings specific to your design.*_*Constant_Pout**PA_One_Tone_Sweep_Freq_Constant_Pout_Display**- embeds all graphs into one display.
