Connect the test equipment

 (DUT) 

to the 

TEST

 port of the measuring bridge and measure the standing 

wave ratio. 

Note. Standing wave ratio is measured in 

SWR

 mode. The graph will be displayed with the vertical axis 

as a numerical standing  wave ratio. The horizontal axis shows the specified frequency range of the sig-
