Figure 20 Basic Display Mode
Key features of this screen are as follows:
1 Distance to Largest PIM Source Indicator
The distance to largest PIM source indicator is a numerical readout of the location of the worst PIM fault in the device
under test. The units can be toggled between metres and feet by touching the units label.
2 Level of Largest PIM Source Indicator
The level of largest PIM source indicator is a numerical readout of the amplitude of the worst PIM fault in the device under
test. The units can be toggled between dBm and dBc by touching the units label.
3 PIM Pass/Fail Threshold
The PIM Pass/Fail threshold is the test limit against which the PIM vs Distance results are compared. Its value can be
changed by touching the on-screen value and typing in the new value at the prompt.
Note that the PIM Pass/Fail Threshold should not be confused with the Pass/Fail threshold on the main application
window, as described in the iQA/iPA Operating Manual. The threshold on the main application window is a customer-
specified value that is used for acceptance testing at a site. The threshold on the RTF Analysis screen is used purely for
troubleshooting purposes – it does not appear on any reports, and should not be used for final site approval.
4 PIM Pass/Fail Indicator
The PIM Pass/Fail indicator displays whether or not the measured results meet the PIM Pass/Fail threshold.
8.4.2 PIM , RL Marker, Zoom Functions and Enhanced Display (iPA)
The iPA provides trace peak markers and 2 other markers that can be used on either Passive Intermodulation or Return
Loss. Depending how the 2 other markers are used, Delta distances can be measured between Return Loss peaks , PIM
Peaks or between a RL Peak and PIM peak using both traces, or from a peak and an entered distance.
As the iPA can have several screens attached as a hotspot client, each device can operate their own markers to look at
different PIM or RL peaks.
