Setup Description
Search/Tracking: ON
Moving Marker 1 to the trace maximum

Step 3. Determine the isolation between Tx and Rx.
Setup Description
Activating Trace 3
Marker 1: ON
Search/Tracking: ON
Moving Marker 1 to the peak near 1.92 GHz
In the example shown in Figure 14-15, the isolation (response value of marker 1) is 6.612
dB.
Step 4. Determine the return loss of Tx.

*1. If you cannot move the marker to the desired peak, use
peak deviation and then execute the search again. (Example:
In the example shown in Figure 14-15, the return loss (response value of Marker 1) is 12.65
dB.
Step 5. Determine the return loss of Rx.
