CCI's PiMPro Tower Series is the first truly portable family of Passive Intermod (PIM) analyzers.  All PiMPro Tower analyzers have real world 40W × 2 output power capability, with a sensitivity of -135 dBm, and can run on battery power for over three hours. The PiMPro Tower 850 has the ability to cover the 850 MHz band, 835-894 MHz.  The analyzer's excellent measurement sensitivity (-135 dBm) as well as its ability to set transmit tone levels down to 20 dBm (100 mW) × 2 makes it the perfect resource for conventional cell sites as well as in-building Distributed Antenna System (DAS) requirements.

The Tower Series demonstrates the perfect synergy of CCI’s world class in-house engineering design expertise for both filters and amplifiers. Each light weight and compact unit is protected by a reinforced backpack case which can easily strap to a climber’s back for top-of-the-tower performance testing. The unit can be safely secured to most any tower structure with its integrated industrial grade clips. Each unit features a superior quality bright TFT capacitive 7.0 inch screen that provides a more friendly user interface. CCI’s simple GUI combined with a powerful CPU make for fast measurement acquisition and site data storage. The portable construction, designed with durable ruggedness and reliability first and foremost, PiMPro Tower Series will prove to be a valuable investment for years to come.


Most LTE sites are configured with radios set at 40 watts or more per carrier and each site can have as many as four carriers per sector.  This means that PIM testing at anything less than 40W × 2 will not accurately simulate live network traffic and is likely to understate actual site PIM levels. The PiMPro Tower Series' 40 watt × 2 power level allows for realistic PIM level testing in the field and at the tower top. The analyzer provides precise measurement of the 3rd and 5th order intermods of any system or component under high-power conditions. In addition to passive intermodulation measurements, the unit will provide VSWR and Return Loss values. PiMPro can be used to verify the integrity of individual passive components including connectors, cable assemblies, antennas, filters, making it an integral performance tool for site and tower technicians.
As a leading provider of wireless base station enhancement products, CCI set out to design and develop a reliable solution to system performance and enhancement challenges. PiMPro employs state-of-the-art technology and is built to meet the ever changing demands and needs of today’s wireless suppliers.


  • On site installation testing of antennas, filters, cable assemblies and other passive components
  • Tower technicians can test antenna installations under real world 40W x 2 conditions at the tower top
  • Mobile operators can isolate site performance issues and perform interference testing

 Measurement & Configuration

 CLASSICXXXX System Configuration System Configuration
System Configuration is the first data entry point for PiMPro users, where all system and report generation parameters are set. Includes settings for Date and Time, Audio Alarm, RF Power on Time interval, central Data Label management, PiMPro registration information and IP address are all keyed in from this screen. Software updates and screen calibrations are also accessed from this screen.
PiMPro’s main measurement screen provides instantaneous PIM measurement in both dBc or dBm. The large display flashes to annunciate the presence of RF power at the output connector. Pass/Marginal/Fail Limits, Output Power, Frequency and IM settings originate from this screen. PiMPro’s unique Return Loss diagnostic feature at high transmit (TX) power, quickly points out open cables.
The PIM vs Time dynamic measurement mode features a graphical representation of PIM as a function of time. Time scale can be set from 10 seconds to 4 minutes. The PiMPro Return Loss feature is also available on this screen.
 CLASSICXXXX Frequency Sweep Frequency Sweep
PiMPro displays a swept receive (RX) PIM range by sweeping the TX carriers from end to end within the set frequency band. PIM frequency response is displayed, exposing the worst case PIM level and the contributing frequencies. Users can immediately transfer the graph to the PIM vs Time feature and run a new test to isolate the causes of the specific PIM.
 CLASSICXXXX RX Interference RX Interference
With both internal amplifiers set to off, PiMPro performs a spectral analysis sweep, for interfering signals. RX Interference mode provides the added ability to discern PIM from external interfering signals in the receive band. External and internal PIM signals are unlikely to be in phase or simultaneous within PiMPro’s narrow receiver range, therefore, making RX Interference a powerful field diagnostic tool.
 CLASSICXXXX ReportGen Report Generator
Report data for all measurement modes can be stored in either, HTML or PDF file format. Users can concatenate a limitless series of measurements with different sector, feeder, color codes, as one single PDF file. Reports can be saved in PiMPro’s internal memory or to external USB memory from the unit’s front panel.
