PIM 31 - Passive Intermodulation Analyzer 2 x 20W
Boonton’s PIM 31 series test systems are precision analyzers
for passive intermodulation generated in RF paths, components
and assemblies. PIM 31 analyzers allow the detailed examina-
tion of components used in radio base stations, in-building-DAS
installations and other systems transmitting radio frequencies.
Components such as coaxial feeder assemblies, jumper cables,
splitters, hybrids, filters, DC blocks, lighting arrestors and anten-
nas, are all potential sources of PIM problems.
Passive intermodulation is an unwanted mixing effect caused
by non-linearity of passive components in the RF path. Inter-
modulation diverts signal energy partially to other frequencies
(spurious), which may fall into receive bands and cause serious
degradation of system performance.
Boonton’s PIM 31 passive intermodulation analyzer emulates
a base station radio by providing two signals, up to 20W each,
thus following the IEC62037 standard for PIM testing. The
frequencies of these carriers are variable within the band of the
analyzer, allowing PIM 31 operators to select the optimal fre-
quencies for their wireless systems. PIM 31 analyzers combine
portability with accuracy and a very high sensitivity of -175 dBc
@ 2x43dBm. They are well suited for both, field use and the
production floor. Applications range from performance evalua-
tion of RF infrastructure, to RF component quality testing.
To provide optimal functionality, Boonton’s PIM 31 analyzers
offer two user interfaces (except UL models). Depending on
the application it can be switched between a functional field
diagnostic mode and detailed analysis mode with accessibility
to all settings and readings. PIM 31 analyzers can be controlled
by external mouse and keyboard or through the built-in touch
screen display. Whether analyzing wireless infrastructure, or
tracking device quality on the production floor, recording of the
measurement results is mandatory for quality management. It
offers a recording capability as a standard feature (except UL
models). Data files or images can be stored, allowing the user to
review and analyze measurements at a later point in time.
