Passive Intermodulation Test Solutions
For all Applications. Made in Germany.

High-speed data transmission in today’s global mobile communications networks demands high efficiency of network infrastructure. Passive Intermodulation (PIM) in a network can cause serious interferences and significantly degrade the network quality and impact KPI figures.
Best-in-Class PIM Test Equipment
Best-in-Class PIM Test Equipment
The cause of Passive Intermodulation is very complex and uncertain. It can be caused by low-grade transmission line components or even loose connectors, dirty surfaces, magnetic materials or the surrounding environment like a rusty roof. As a global leader of RF connectivity solutions, Rosenberger has a strong expertise in manufacturing low-PIM components as well as PIM Test and Measurement solutions for all applications:
  • Site testing
  • Testing in production environment
  • Test lab and product design environment

PIM Hunting
Reliable Classification and Detection of External PIM

The versatile Rosenberger 2-port PIM testing solution combines the functionality of a traditional one port test system with a new 2-port test system to distinguish internal PIM-sources from external PIM-sources.
PIM Hunting

Furthermore the additional RX port on the 2 port filter unit enables the built-in receiver. In combination with a PIM hunting probe it is possible to detect external PIM-sources around the antennas. With this integrated solution an additional spectrum analyzer to operate the PIM hunting probe is not needed.
  • PIM test under typical scenarios (e.g. 2 antennas using different wavebands)
  • Configurable menu (1 or 2 port measurement)
  • Clearly differentiate internal from external PIM
  • Additional RX port for connection of test probe for external PIM detection
  • Integrated DTF module
  • No separate spectrum analyzer needed
  • Adjustable PIM level beep tone via bluetooth speaker or remote tablet
Site Testing
Site Testing
PIM Site Analyzer alpha
PIM Site Analyzer alpha
Broadband. Precise. Future-proof.

The Rosenberger portable and multifunctional broadband PIM Site Analyzer α provides the best alternative of performing the most precise and efficient PIM tests on site.
The PIM Site Analyzer α consists of a single master unit with band-specific, interchangeable filter units, since the form factor of the filter units is the same. Take out one filter unit, e.g., 900 MHz, and replace with another filter unit, e.g., 1800 MHz, without any calibration of the filter unit, potential adaptors, test cable, or operational mode(s). Future-proof plug and play concept covering 700 to 2700 MHz.
  • Broadband base unit 700 to 2700 MHz with field interchangeable, band-specific filter units
  • Stressed PIM tests – continuous wave (CW) signal simulates real operating conditions of the base station (in conformity with IEC 62037-1)
  • Outstanding PIM performance < -125 dBm (< -130 dBm typical)
  • No on-site calibration
  • Accuracy of < 0.3 m for PIM distance to fault (DTF) measurement
  • Future-proof for upcoming bands

  • Optional broadband VSWR/RL module incl. DTF measurement (error correction with open/short/match)
  • Built-in WiFi for remote control via optional Android tablet
  • Operation via batteries or external power supply
  • VSWR/return loss measurements
  • Antenna isolation measurement
  • Integrated spectrum analyzer
  • 12" touchscreen
  • Intuitive software operation
  • Exchangeable test port adaptors (7-16 and 4.3-10) 

Testing in Production Environment
PIM rack analyzer
PIM rack analyzer
Exceptionally modular. Precise. Efficient.

Rosenberger Rack Analyzers are designed to make PIM tests in production or test lab environments exceptionally modular, precise, and efficient.

The budget-friendly broadband base unit concept offers maximum flexibility thanks to the option of connecting up to 11 filter units to one base unit. Integrated DTF measurement enables faster fault-finding by accurately pointing out the source of PIM.

With the plug-and-play filter concept, intuitive software operation, and easy-to-replace dust filters, it is possible to create a significant reduction in production downtime caused by changes in test frequencies or maintenance and servicing work.


  • Broadband base units 700 to 2200 MHz and 2100 to 2700 MHz
  • Connect up to 6/11 filters to one base unit via optional easy-to-install switch matrix
  • Time-efficient, automatic band switching when measurement band is changed (thanks to the optional switch matrix)
  • Designed for 24/7 production use


  • Intuitive, user friendly software operation
  • Easy-to-replace dust filters to reduce downtime caused by maintenance work
  • No production downtime when setup is rearranged (plug-and-play filter inserts)
  • 9" touchscreen, Win7 OS
  • Temperature controlled fan for quiet operation
  • Optional safety port to remote disable amplifiers from test chamber contact
  • Exchangeable test port adaptors (7-16 and 4.3-10)
Test Lab and Product Design Environment
Portable. Flexible. Budget friendly.

Rosenberger desktop analyzers are portable and flexible for R&D and test labs. The budget friendly broadband base unit concept offers maximum flexibility to include another extension filter to a base unit (basic line) or add any other filter unit in the range of 700 to 2700 MHz to the base unit (multifunction line). It allows continuous flexibility in an ever changing environment.


  • Reduction of T&M investment cost (for multiband-testing)
  • High flexibility/portability in test environment


  • Basic line: 1 additional filter unit can be added*
  • Single band units for band specific testing
  • Outstanding dynamic residual IM-Level < -171 dBc (2 x +43 dBm), typical -174 dBc
  • Fast & efficient PIM testing

*698 to 1000MHz: one base model 700, 800, 850, 900 MHz can have one additional filter from any other of these frequency bands.
1800 to 2100 MHz: one base model 1800, 1900, 2100MHz can have one additional filter from any other of these frequency bands.
