format. It allows users to select one of the following data groups for displaying
the value of the marker.
⚫ Lin/Phase: shows the converted magnitude and the phase at the current
marker position.
⚫ Log/Phase: shows the magnitude (in dB) and the phase at the current
marker position.
⚫ Real/Imag: shows the real and imaginary components at the current
marker position.
⚫ R + jX: shows the real and imaginary components of the impedance at the
current marker position.
⚫ G + jB: shows the real and imaginary components of the admittance at the
marker position.
5. Polar
The distance from the trace to the origin of the polar axis is expressed as the
magnitude of the measurement result; and the phase is expressed as an angle
counterclockwise from the positive X-axis to the line connected between the
trace and the origin.
The polar chart allows users to select one of the following data groups for
displaying the value of the marker.
⚫ Lin/Phase: linear magnitude and phase.
⚫ Log/Phase: log magnitude and phase.
⚫ Real/Imag: real and imaginary parts.
6. Lin Mag
Sets the trace format to linear magnitude. The trace is represented in the form
of Lin Mag for the measurement results.
7. SWR
SWR = . Wherein, ρ represents the reflection coefficient. The unit is N/A.
8. Real
Indicates the real part of the complex parameter.
9. Imaginary
Indicates the imaginary part of the complex parameter.
10. Expand Phase
The trace represents the phase of the measurement results. It can display phase
above 180°and below -180°. The unit is degree (°).
11. Positive Phase
The trace represents the phase of the measurement results. The display range is
from 0°to 360°. The unit is degree (°).
