Swr Format; Real Format - Agilent Technologies 8753ET User Manual

SWR Format

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

Real Format

The softkey displays only the real (resistive) portion of the measured data on a Cartesian format.
REAL
See Figure 7-13. This is similar to the linear magnitude format, but can show both positive and negative
values. It is primarily used for analyzing responses in the time domain, and also to display an auxiliary input
voltage signal for service purposes.
