Measurement by various formats
Here describes about measurement methods by various formats of reflection measurement
(return loss, reflection coefficient, standing wave ratio, S parameter and impedance).
Return loss (LOG MAG format setting) measurement
Adjust the scale to see the display trace (magnitude ) easily.

Letting the reflective coefficient =
ρ
(= reflective signal/incident signal), the return loss
is represented with the following equation.
Return loss = -20log (
ρ
)
The display on the screen (return loss) is as follows.
