Shulong,
Touchstone files only specify port numbers. Every port is both an input and an
output port. Typically, however, for a two-port device, port 1 is referred to
as the "input port" and port 2 as the "output port". This is because the
desired direction of signal propagation is typically from port1 to port2.
Now, if the device was measured backwards.... well, I think you can guess what
happens.
