Linear Magnitude Format
The
i~~~:~.~:~~~~
softkey displays the
linear
magnitude format (see F’igure 6-16). This is a
Cartesian format used for
unitless
measurements such as reflection coefficient magnitude
p
or
transmission coefficient magnitude
T,
and for
linear
measurement units. It is used for display of
conversion parameters and time domain transform data.

The
RR&;
softkey reformats a reflection measurement into its equivalent
SWR
(standing wave
ratio) value (see F’igure 6-17). SWR is equivalent to (1 +
p)/(l
-
p),
where
p
is the reflection
coefficient. Note that the results are valid only for reflection measurements If the
SWR
format
is used for measurements of
Sal
or
$312
the results are not
valid.
