The Anritsu PIM Master is capable of producing 80 Watts of RF power in the cellular communications bands. Users must take precautions to minimize exposure to these RF fields:
Always terminate the PIM output port of the test equipment into a load, a loaded line, or a line that will radiate or absorb the energy before beginning a PIM test.
Confirm that the PIM Master RF power is off after a PIM test.
Always confirm that the PIM RF power is off before disconnecting a coaxial connection, otherwise RF burns may result. Immediate burns to fingers or eyes can result from exposure to live connectors.
Ensure that all antennas under test are placed so that no personnel are exposed to RF levels that exceed the maximum allowable exposure.
Introduction – PIM versus Time Analyzer
The PIM Master includes a PIM versus Time measurement that tracks not only the instantaneous PIM level but also records the Peak PIM level experienced throughout a fixed frequency PIM test. This measurement is useful for dynamic PIM tests because it not only captures the Peak PIM value for pass/fail determination, but provides a visual indication of the stability of the system under test.
A PIM versus Time measurement is the basic test to pass or fail a site. Distance‑to‑PIM is a diagnostic tool to find any PIM that is detected in the PIM versus Time measurement. Noise Floor measurements reveal any external interference that might produce undesirable PIM test results.
