TESTING FOR
PASSIVE INTERMODULATION DISTORTIONS
COMMUNICATION TESTING SERVICES

The new AWS, UMTS, & LTE technologies are intended to be used for the transmission of high speed data transfer.  To
accomplish this with reliable proficiency, engineers have discovered that the quality of the entire RF system needs to be nearly
perfect. It has always been understood that an RF signal can be dramatically effected by random distorted signals within the
receive band of a RF system.  These unwanted signals will show up as excessive frequency noise that can be within the bandwidth
of a receive radio.  This condition can cause degraded radio capacity and call failures. The condition is referred to as Passive
Intermodulation Distortion (PIM).
The improvement of system component quality can reduce and even eliminate this condition.  PIM testing is designed to identify
the existence of the unwanted signals that create RF interference.  When the source of the unwanted signal is identified, corrective
steps can be taken to eliminated the problem. This process requires an experienced testing professional that can correctly analyze
the test data and recommend solutions to the problems that have been identified.
