Marker Mode
• Marker
Move the cursor to the location that you want to measure, and set a marker. When you are
measuring return loss and splice loss, they are calculated automatically when you set all the
markers that are necessary for the measurement method that you are using.
• Line
After you select the line marker that you want to operate from a set of multiple line markers,
move the selected line marker directly. The value of the line marker’s section is calculated, and
the return loss and splice loss are measured. Each value is calculated in real time as you move
the line marker.
