8.2.1.1       Results Display Mode Buttons (iQA)

The results display mode buttons allow the user to switch between the different results formats in the RTF 

Analysis window.  The different display modes are discussed in detail in sections to follow, but in summary:

8.2.1.2       Basic Mode (iQA)

This is the default results display mode.  It is a simple numerical readout of the location and amplitude of the 

largest PIM fault in the device under test.

8.2.1.3       PIM vs Distance Plot (iQA)

This mode plots PIM amplitude as a function of distance.  Sources of PIM in the device under test show up as 

peaks on the plot.

8.2.1.4       Return Loss vs Distance Plot (iQA)

This mode plots return loss as a function of distance.  Sources of poor return loss in the device under test show 

up as peaks on the plot.

8.2.1.5       Overlay Plot (iQA)

This mode plots the PIM and Return Loss vs Distance traces on the same set of axes.

8.2  

Layout of the RTF Analysis Window

8.2.1       iQA Analysis Window

The RTF Analysis window is shown in Figure 17 in its default display mode.  This window is available only when the RTF 

module is connected to the iQA.
