Battery-operated, high power Passive Intermodulation (PIM) testing solution for the major wireless standards in use around the world. The PIM Master’s small size and light weight, combined with battery operation, make it the ideal solution for verifying PIM performance at difficult to access sites such as Remote Radio Head (RRH) installations or indoor Distributed Antenna Systems (DAS).
Frequency options available:
* LTE 700 MHz (Upper & Lower)
* Cellular 850 MHz
* E-GSM 900 MHz
* DCS 1800 MHz
* PCS 1900 MHz
* PCS/AWS 1900/2100 MHz
* PIM vs. Time
* Swept PIM
* Distance-to-PIM™ (DTP)
The PIM Master includes Anritsu’s patented Distance-to-PIM (DTP) technology for accurately determining the location of PIM faults, both inside the feed system as well as beyond the antenna. Distance-to-PIM allows technicians to quickly and efficiently locate PIM sources at a site resulting in quicker site repairs and lower cost.
The MW82119A is a high performance PIM test solution allowing operators to adjust output power from +25 dBm (0.3 Watts) to +46 dBm (40 Watts). PIM interference is highly dependent on the power level being transmitted by the system. By matching the PIM test power level more closely to the actual power level used at the site, operators will gain a clearer understanding of the true interference generated by both the RF infrastructure and the environment where the antenna is placed.
PIM is a form of intermodulation distortion that occurs in passive components normally thought of as linear, such as filters, combiners, surge protectors, cables, connectors, and antennas. However, when subject to the high RF powers found in cellular systems, these devices can generate spurious signals.
PIM shows up as a set of unwanted signals created by the mixing of two or more RF signals in a non-linear device, such as in a loose or corroded connector, or in nearby rust. Other names for PIM include the "diode effect" and the "rusty bolt effect".
Many symptoms could be indicators of PIM problems. These include:
* Receiver desensitization (raised noise floor)
* Rx Diversity alarms
* Spectral regrowth in the transmitter mask
* Excessive dropped/blocked calls
* Cell site coverage shrinking
* Complaints of interference from neighboring cell site owners
