SWR Format The softkey reformats a reflection measurement into its equivalent SWR (standing
wave ratio) value. See Figure 7-12. SWR is equivalent to (1 + ρ)/(1 − ρ), where ρ is the
reflection coefficient. Note that the results are valid only for reflection measurements. If
the SWR format is used for measurements of S21 or S12 the results are not valid.
