Measurement of S-parameter

We have seen how h-parameter are measured. How about S-parameter?

For text_wrap_inline2851, we terminate the output port of the network and measure the ratio text_wrap_inline2853 to text_wrap_inline2855. Terminating the output port in an impedance equal to the characteristic impedance of the transmission line, as shown in Figure 8, is equivalent to setting text_wrap_inline2857, since a traveling wave incident on the load will be totally absorbed.
