Why do I receive an error if I run the example from the documentation for the Free Space Path Loss Block in the Communications Blockset 2.5.1 (R13SP1)?

There is an example model shown in the documentation for the Free Space Path Loss Block in the Communications Blockset. If I create this model in Simulink and try to run it, I get the following error:
--> Error reported by S-function 'sdspsigattrib' in block 'untitled/Free Space Path Loss/Check Input Signal/Check Signal Attributes/Check Signal Attributes':
Input must be complex.
--> An error occurred while propagating real signal from block 'untitled/Free Space Path Loss/Check Input Signal/Check Signal Attributes/In1', output port 1.

The documentation has been corrected for Release 14 SP1 (R14SP1). For previous releases, read below:
This is an error within the documentation for the Communications Blockset within the Block Reference for the Free Space Path Loss block.
The documentation should show a complex input into the block.
