Introduction – Distance‑to‑PIM™ (DTP) Analyzer
In addition to PIM testing, Anritsu Company offers the Distance‑to‑PIM™ (DTP) Analyzer. DTP analysis offers distance information to PIM sources for cellular sites with internal PIM problems and antenna PIM problems. This DTP analysis includes the surrounding outside environment with external PIM problems.
This chapter describes the setup, calibration, and testing procedures for DTP analysis. The Distance‑to‑PIM™ (DTP) Analyzer firmware resides within the PIM Master, not within the handheld instrument. When the PIM Master is connected to your PIM‑supported Anritsu handheld instrument, a software handshake informs the handheld instrument, and the Distance‑to‑PIM™ (DTP) analyzer features are displayed in the relative menus. The choice between PIM analysis and Distance‑to‑PIM™ analysis is made in the Measurements menu.
Warning 
The Anritsu PIM Master is capable of producing up to 100 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 2 in Figure: PIM Master Connector Panel).
Ensure that all antennas under test are placed so that no personnel are exposed to RF levels that exceed the maximum allowable exposure.
