(Figure 3-7).
The following parameters are measured between marker A and B. Changing either marker will
change.the.record.accordingly.
• A-B:.Distance.between.two.markers.
• 2Pt. Loss: Loss between two markers; power difference between two markers.
• 2Pt. Atten:.2.points.loss.of.unit.length.
The specific operations of the above items are explained in more detail later in this manual.
