9.11.2. Turning on, off and setting the type of the marker is performed by the marker status button:
Off
– marker off;
Point
– the marker is set at a point on the plot at a frequency specified by the user;
Delta
– marker for measuring increments relative to the reference marker.
When multiple delta-markers are set, the first delta-marker automatically becomes the reference
marker.
On the plot, the delta-markers are displayed with the letter D, the reference marker with the letter R.
It is also possible to set a marker when you touch the screen in the area of interest of the plot with a
duration of about two seconds. If there are no markers set on the chart, then as a result of a long touch,
marker 1 will appear. When repeating, the next marker in a row.

Auto
The values are displayed in the interpretation corresponding to the displayed
plot. Switching the plot automatically changes the type of interpretation.
Re, Im
Displaying the amplitude of the real and imaginary parts of the complex reflec-
tion coefficient.
LMag, Phase
Displaying magnitude in decibels and phase in degrees
SWR
The standing wave ratio (VSWR).
Z=R+jX
Displays the active and reactive parts of the impedance in ohm. Type of reactivi-
ty-capacitance or inductance.
Y=G+jB
Displays the active and reactive parts of the admittance in millisiemens (mS).
Type of reactivity-capacitance or inductance.
9.11.4. Enter the frequency at which the marker will be set.
There are several ways to enter and change the frequency at which the marker is located:
By pressing the button with the frequency display and further transition to the menu for enter-
ing numerical values.
By pressing the navigation buttons
and
.
Moving the marker on the screen using a grip with your finger or stylus.
Moving the marker and changing the frequency will occur with a Step equal to:
