Abstract
A method for locating the source of a passive intermodulation (PIM) fault in a radio frequency (RF) system, the method comprising: a) generating a PIM fault fingerprint database by: modelling an RF network; defining a plurality of PIM fault patterns for the modelled RF network by defining PIM faults at one or more sources; simulating a received RF signal for each respective PIM fault pattern; generating the PIM fault fingerprint database in dependence on the simulated received RF signals for each defined PIM fault pattern; b) measuring an RF signal for a real network having a PIM fault and abstracting the measured RF signal to define a given signal; c) searching and matching the given signal using the fingerprint database to determine the PIM fault pattern; and d) locating the source of the PIM fault, or giving a further measuring guideline in dependence on the determined PIM fault pattern.
