Standing wave ratio (SWR format setting) measurement
The following operation is performed to display the return loss as the standing wave
ratio (SWR).
[FORMAT] {More 1/2} {SWR}
[SCALE] {AUTO SCALE}
SWR=1 corresponds to the state of perfect matching.
The related expression between SWR and reflection coefficient ρ is as follows.
SWR = (1+ρ) / (1−ρ)
The display on the screen is as follows.
