them, and finally obtain the average loss of the cable. Limit value search process is as follows:
Press 【Marker】to enter the marker menu, and the Marker 1 defaults to be in open state at this time;
Select [Peak] menu to place Marker 1 onto the peak position of the cable loss curve;
Select [Marker 1 2 3 4 5 6] menu again, the menu becomes into [Marker 1 2 3 4 5 6] at this time, and then select [Marker Off
On] menu to open Marker 2;
Select [Valley] menu to place Marker 2 onto the peak position of the cable loss curve;
Upon the cable loss values shown by Marker 1 and Marker 2, sum and average them to obtain average loss of the cable.
3.2.3. DTF Measurement
DTF (Distance To Fault) measurement, also called fault point location measurement, is a kind of performance verification and fault
analysis tool in the maintenance and repair process of antenna and transmission line. DTF function of S3101A/B is realized by
adopting the measurement technique named Frequency-Domain Reflectometry. In engineering applications, DTF measurement
