Figure 4-5 shows an example of a typical DTF return loss trace.

Figure 4-5. Typical DTF Return Loss Trace

In the above example:

Marker M1 marks the first connector, the end of the Site Master phase stable Test Port Extension cable.

Marker M2 marks the first jumper cable.

Marker M3 marks the end of the main feeder cable.

Marker M4 is the load at the end of the entire transmission line.

Procedure - DTF-SWR Mode

The following steps explain how to measure DTF in SWR mode.

Step 1. Press the MODE key.
