Linear Magnitude Format

The ,s;e,,.~~~:,, softkey displays the linear magnitude format (see F'igure 6-17). 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 .Zm?. softkey reformats a reflection measurement into its equivalent SWR (standing wave
ratio) value (see Figure 6-18). 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 $1 or S~Z, the results are not valid.
