Marker
When a marker is added to a time-domain parameter, the distance parameter is
automatically displayed in the marker reading. These settings only affect the display of all
markers of the active measurement (Unless the distance marker unit is coupled in the trace
coupling box).
Click
Math→Time Gating→Gating Setup→Marker
to open marker setting interface. Set
the marker mode, units, and velocity factor in this interface.

Marker mode:
Specify the marker mode to determine the correct marking distance
displayed. Generally,
Auto
can be selected when measuring S parameter,
and
Reflection
or
Transmission
can be selected when measuring any
ratio parameter.
⚫
Auto:
If the measurement parameter is S parameter,
Reflection
or
Transmission
will
be selected automatically. If the measurement parameter is a non-S
parameter,
Reflection
will be selected automatically.
⚫
Reflection:
Displays the distance from the source to the receiver and the return path,
then divides by 2 (compensated return path).
⚫
Transmission:
Displays the distance from the source to the receiver.
Units:
Specifies the unit for the displayed marker distance value, there are three options:
meter, feet, inches.
Velocity factor:
Set the velocity factor of the transmission line, where the value of PE is 0.66,
PTFE is 0.7 and the corresponding value of vacuum is 1.
