R3765/67G Series Network Analyzer Operation Manual
3.6 Measurement Samples of Simple Reflection Characteristics
3-28
S parameter (POLAR format setting) measurement
The following operation is performed to display polar coordinates.
[FORMAT]
{More 2/2}
{POLAR}
The display on the screen is as follows.
Each coordinate shows the magnitude and the phase as follows.
(a) The magnitude is displayed with line and the size of the magnitude is displayed with
the radius of the circle.
The center of the circle : Reflection coefficient 0 (The state of perfect matching)
The most outer circumference of the circle :
Reflection coefficient 1 (Full reflection)
(b) The phase is displayed with the angle from the plus direction of X axis.
It shows that the direction of 3 o’clock is phase angle 0
°
and the phases of the incident
signal and the reflection signal are the same.
