7 PIM 31 OPERATION
PIM31 Test Systems were developed to measure and analyze PIM data of RF-
components, cables, or complete RF systems.
Operation Modes for Different Applications: Field Mode / Analyzer Mode
Depending on the application, the users’ requirements will be different. The main
task at a base station site is to quickly analyze the RF Path, and document the
measurements. If unacceptable PIM levels are detected the PIM31 can be used
to identify and pin-point problematic components. When testing base stations,
typically, the frequency and power settings of the test equipment are site specific.
Focus lies on quick measurement and documentation of data. PIM31 test
systems provide this easy to use functionality in the Field Mode. All base station
test parameters can be stored in the PIM31 test system, including feeder and
sector information. By selecting the base station, the user is ready to go. For
preventive maintenance it can be very helpful to compare actual with historical
data, which the PIM31 offers this as well. Measurements can be stored in the
system as .log files. Whenever data are logged, the log field stores
measurements, test system settings, and even complete information of the base
station. The operator can view the historical data of a base station at any time
and analyze if readings have changed compared to historical measurements.
