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.

SWR Format

.;.......I .

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.
