  • Page 11: Why Test For Pim

    1-4 Why Test for PIM? Why Test for PIM? Anritsu has developed the PIM Master to verify and troubleshoot Passive Intermodulation (PIM). The PIM Master generates two high-power tones, usually in the transmit band of interest. It displays and measures the third-order, fifth-order, or seventh-order intermodulation products returning from the DUT to the PIM Master.

  • Page 29: Verifying The Pim Test Cable

    Verifying the PIM Test Cable When testing, cables are connected and disconnected many times. In order to save wear on the PIM test port cables and adapters, Anritsu recommends removing the O-rings. This allows getting a sufficiently tight connection without unnecessary stress on the connectors.

    The IM products of interest are in the same frequency range that is used by mobile user equipment to communicate with the base station. It is therefore possible for nearby mobile equipment to generate signals that are high enough to interfere with your PIM measurement. 2-10 PN: 10580-00402 Rev. E MW82119B MG...

DTP quickly and accurately identifies the location of PIM faults inside the feed system as well as beyond the antenna.

    Antennas. The only problem is that this work was done with FACTORY testing in mind. The IEC specification does not currently address how to apply dynamic stress in the field. Operators, therefore, need to define their preferred test methods. The MW82119B PIM Master has the PIM versus Time measurement mode, which supports dynamic testing and keeps track of the worst case value for the duration of the test.

    Chapter 7 — Swept PIM The Anritsu PIM Master is capable of producing 80 Watts of RF power in the cellular communications bands. Users must take precautions to minimize exposure to these RF fields: Always terminate the PIM output port of the test equipment into a load, a loaded line, or a line that will radiate or absorb the energy before beginning a PIM test.

    Confirm that connections are secure. High power RF signals are emitted from the Warning PIM test port and can cause bodily injury. Anritsu recommends using a torque wrench for this connection. This device (DUT) may be the main feeder cable from the tower or a simple jumper cable.
