Anritsu launches trouble-finding tool for analyzing 850 MHz cellular band networks

By Telecom Lead Team: Test and Measurement solutions provider Anritsu Company
has introduced the MW8208A PIM Master.


The innovative test solution brings the
inherent advantages of Anritsu’s Distance-to-PIM technology to 850 MHz cellular
band applications. Distance-to-PIM helps make the MW8208A a comprehensive
trouble-finding tool that allows field technicians to accurately locate the
source of passive intermodulation (PIM), whether it is in the base station
antenna system or in the surrounding environment.


The MW8208A PIM Master enables users to
uncover the distance and relative magnitude of all static PIM faults simultaneously,
including those resulting from dirty connectors, corroded connectors,
over-torqued connectors, and microscopic arcing connectors. PIM Master can also
accurately locate PIM outside the antenna system.


Similar to Anritsu’s
Distance-to-Fault technology designed into its Site Master cable and antenna
analyzers, Distance-to-PIM helps eliminate one of the biggest problems facing
wireless network deployment and operation.


The MW8208A generates two high-power tones
in the transmit band of a base station and can measure the 3rd, 5th, and 7th
order intermodulation products in the receive band coming down the same cable.
Utilizing the GPS feature on the Anritsu handheld analyzers, users can record
the location of the measurement.


Utilizing 40 Watts simulates real-world
power that activates the PIM that might not otherwise be activated by 20 Watt
systems. In addition, using double the power allows PIM Master to locate
intermittent failures due to light corrosion, high-traffic loading, or changing
weather conditions.


The MW8208A is designed to integrate with
Anritsu’s S332E/S362E Site Master cable and antenna analyzers, MS2712E/MS2713E
and MS272xC Spectrum Master handheld spectrum analyzers, MT8212E/MT8213E Cell
Master handheld analyzers, and the MT8221B/MT8222B BTS Master handheld


The MW8208A is the newest member to the
ever-growing PIM Master family. It also includes the MW8209A for the E-GSM band
and the MW8219A for the PCS/AWS bands.
