OIP3 Testbench
Use the OIP3 Testbench block to verify the output third order intercept (oip3) of an Amplifier block.
Open the model.
open_system('oip3_example.slx')
Open the amplifier block and change the following under Nonlinearity:
Intercept points convention = Output
IP3 = 20
In the OIP3 Testbench block, clear the following:
Simulate noise (both stimulus and DUT internal)
Show Response spectrum
Run the model. You will see that the display shows a oip3 value of 20 dB.
