%% Single Pole Triple Throw Switch
% Use the |SPnT| block to create a single pole triple throw switch to switch
% a signal between three outputs.
%%
% Open the model.
% 
% <<../SPnT_1.png>>
% 
%%
% The model consists of:
%%
% 
% * Sine Wave block to generate a sine wave of amplitude 1.
% * Power Meter block to determine the power of the sine wave. This is the
%   input power. The input power is 30 dB.
% * Inport and Configuration blocks connected to the "In" port of the SPnT
%   block.
% * A Constant block connected to the "Ctl" port of the SPnT block. This
%   signal is used to control the switch outputs. 
% * SPnT switch block with 3 output ports.
% * Outport 1, Outport 2, Outport 3, and Power meter blocks to calculate
%   the power of each output signal.
% * Display block to display the three outputs.
%%
% Run the model. 
% 
% <<../SPnT_2.png>>
% 
%%
% The Display block shows that the signal power is available through the first
% port of the switch as the "Ctl" port is set to 1. 
%%
% Open the SPnT block to see set values. Currently the switch is set to
% "Absorptive" using the "Load Type" parameter. 
% 
% <<../SPnT_4.png>>
% 
%%
% Change the "Load Type" value to "Reflective".
%%
% Change the value of the Constant block to 3. 
%% 
% Run the model again.
% 
% <<../SPnT_3.png>>
% 
%%
% The Display block shows that the signal power is available through the
% third port of the switch as the "Ctl" port is set to 3.
