Figure 20 Basic Display ModeKey features of this screen are as follows:1 Distance to Largest PIM Source IndicatorThe distance to largest PIM source indicator is a numerical readout of the location of the worst PIM fault in the deviceunder test. The units can be toggled between metres and feet by touching the units label.2 Level of Largest PIM Source IndicatorThe level of largest PIM source indicator is a numerical readout of the amplitude of the worst PIM fault in the device undertest. The units can be toggled between dBm and dBc by touching the units label.3 PIM Pass/Fail ThresholdThe PIM Pass/Fail threshold is the test limit against which the PIM vs Distance results are compared. Its value can bechanged 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 applicationwindow, 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 fortroubleshooting purposes – it does not appear on any reports, and should not be used for final site approval.4 PIM Pass/Fail IndicatorThe 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 ReturnLoss. Depending how the 2 other markers are used, Delta distances can be measured between Return Loss peaks , PIMPeaks 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 atdifferent PIM or RL peaks.1243Operating Manual | Passive Intermodulation and Return Loss Fault Ranging Device32
