Measuring Standing Wave Ratio (SWR)

Press Format SWR Scale Ref AUTO SCALE so the analyzer shows the same data in terms of standing-wave-ratio (SWR), as shown in Figure 2-13.

Now the analyzer shows the measurement data in the unitless measure of SWR where SWR = 1 (perfect match) at the bottom of the display.
