Works with IQA Models 1800, 1900, 1921 and 2101. This Module requires the option to be installed in the software first.

   Range To Fault (RTF) is an exciting new technology from Kaelus that enables operators to accurately measure the location of PIM and Return Loss faults in their RF infrastructure. Reflection data together with PIM data provides an unmatched level of clarity for identifying the location of faults in the RF path. The RTF system consists of an RTF Module, interconnecting cables and a "RTF Enabled" iQA series PIM test instrument. Customers can purchase a new "RTF Enabled" PIM test analyzer from Kaelus or upgrade their existing A or B-series iQA test equipment to support RTF measurements.


  • Accurately identify the location of PIM and Return Loss faults in the RF path
  • Simple to operate, highly intuitive touch screen user interface
  • Overlay PIM and Return Loss vs. distance data for enhanced troubleshooting capability
  • Quickly switch between different test modes without disconnecting the line under test
  • Compatible with any "RTF Enabled" iQA series PIM test instrument from Kaelus
  • Speeds site repairs by guiding operators to the location of PIM faults
  • Factory upgrades available for existing A and B-series iQA test instruments
  • Before PIM testing, the RTF Module performs a Return Loss safety check to warn the operator before transmitting high RF power into a poor match

Peak Return Loss

   When the RTF module is attached a low power Return Loss vs. distance measurement will be made prior to activating the high power PIM test tones. If the peak calculated Return Loss is greater than a user specified value a warning will be presented to the operator along with the distance to the failing location. The operator has the option at this point to either abort the test or continue with the PIM measurement. This safety feature has been added to help prevent accidental high power RF transmissions while the feed system is open for repairs.

Distance to Largest PIM Source

   With an RTF Module attached the iQA user software provides four different views the operator can use to analyze PIM faults at the cell site. The "Basic" view clearly identifies the distance and magnitude of the largest static PIM fault on the line. For fastest results, Kaelus recommends methodically eliminating the largest PIM fault and repeating until all static PIM sources have been removed. Once the static PIM sources are removed, the operator can proceed to dynamic PIM testing to certify that the PIM performance is stable and robust.

PIM versus Distance

   With a single button push, the operator can switch to "PIM" view to see the relative magnitude of all PIM sources on the line. A marker function is provided allowing the user to jump from peak to peak displaying the magnitude and distance to each PIM fault. Kaelus¿ RTF solution utilizes proprietary enhanced resolution algorithms that enable the user to resolve closely spaced PIM faults that a standard FFT analysis can not see.
