SWR Format
The
softkey reformats a reflection measurement into its equivalent SWR (standing
wave ratio) value. See
. 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 S
the SWR format is used for measurements of S
21
or S
12
the results are not valid.
