PIM Site Analyzer alpha

PIM Site Analyzer for Mobile Network Site Testing

The broadband PIM Site Analyzer alpha from Rosenberger is a mobile and multifunctional solution for precise Passive Intermodulation (PIM) measurements directly at mobile radio base stations. Designed for efficient site testing in modern mobile networks, the system enables fast and reliable fault analysis in the field.

The measurement system consists of a base unit and band-specific, interchangeable filters with an identical form factor. Filters can be swapped easily — for example, from 900 MHz to 1800 MHz — without any additional calibration of filters, adapters, test cables, or operating modes.

The future-proof plug-and-play concept covers a frequency range from 700 to 2700 MHz (optional 600 MHz), making it an ideal solution for current and next-generation mobile network technologies.

Reliable Detection and Classification of External PIM Sources

The universal Passive Intermodulation (PIM) test solution combines the functionality of a classic 1-port system with a modern 2-port test system. This enables reliable identification and clear classification of both internal and external PIM sources.The advanced PIM measurement technology allows precise analysis and accurate assessment of cellular network quality.

1-Port and 2-Port PIM Measurement Principles

1-Port Measurement
Equal power levels of signals f1 and f2 are applied at the PIM source. If PIM is detected, the root cause may located inside the transmission line or externally beyond the antenna.

2-Port Measurement
Signal f1 is applied to antenna 1 and signal  f2 to antenna 2. Passive intermodulation cannot occur within the transmission line. If PIM is detected, the interference source is clearly external.

PIM Hunting – Localization of External PIM Sources

An optional RX port on the 2-port filter allows activation of the integrated receiver. In combination with a PIM probe, external PIM sources in the antenna environment can be reliably located.
This integrated PIM hunting solution enables the use of a PIM probe without the need for an additional spectrum analyzer, significantly reducing equipment requirements and measurement effort.

Benefits

• PIM testing of typical deployment scenarios, such as two antennas operating with different frequency bands
• Configurable measurement menu for 1-port or 2-port operation
• Clear differentiation between internal and external PIM sources
• Additional RX port for connecting a PIM probe to detect external interference
• Integrated Distance-to-Fault (DTF) module
• No additional spectrum analyzer required
