%% OIP2 Testbench
% Use the |OIP2 Testbench| block to verify the output second order intercept
% (OIP2) of an |Amplifier| block.
%%
% Open the model. 
open_system('oip2_example.slx')
%%
% Open the amplifier block and change the following under
% *Nonlinearity*:
% 
% * Intercept points convention = Output
% * IP2 = 10
% 
%%
% In the OIP2 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 OIP2 value of 10 dB.
