Warning 
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 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 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.
RF power can be immediately turned off with the Emergency Stop button (item 3 in Figure: PIM Master Connection Diagram – Top).
Ensure that all antennas under test are placed so that no personnel are exposed to RF levels that exceed the maximum allowable exposure.
Introduction – Swept PIM Analyzer
PIM measurements are the vector sum of all PIM signals that are generated on a line at the IM frequency being tested. When multiple PIM sources exist, it is possible for the signals to combine out of phase at a particular test frequency to indicate a passing result when the individual PIM levels are actually failures. A Swept PIM test varies the IM frequency over a range of frequencies to provide you with a clearer picture of the true PIM performance of the system.
