[TowerTalk] Remote switch

Not dumb at all.  To simulate what you are really looking for, I would measure 
s21 between the input port and an unselected output port, if it is open.  The 
selected port should be terminated in 50 ohm. The instrument terminates the 
measured port(s) so no additional terminations are necessary or desired.  
Clearly you can't measure a shorted port.
