General Information


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 (Figure: PIM Master MW8219A Connector Panel). Ensure all antenna’s under test are placed so that no personnel are exposed to RF levels that exceed the maximum allowable exposure.

Scope of the PIM Master User Guide

The PIM Master User Guide describes the connection and operation of the MW8219A PIM Master and the PIM Analyzer and Distance‑to‑PIM Analyzer modes that are associated with supported Anritsu handheld instruments.

This chapter provides a general overview of PIM analysis and the Anritsu PIM Master. It also includes instructions on care and user maintenance, details frequency range pairs, illustrates a typical PIM analysis setup, and reviews updating the PIM Master firmware.

PIM Analyzer provides an instrument overview, parameter setup, and connection setup for PIM analysis. It also includes a comprehensive review of the menus that are available in the PIM Analyzer mode on Anritsu handheld instruments.

Distance‑to‑PIM™ (DTP) provides an instrument overview, parameter setup, and connection setup for Distance‑to‑PIM analysis. It also includes a comprehensive review of the menus that are available in the Distance‑to‑PIM Analyzer mode on Anritsu handheld instruments.

Programming Commands lists available SCPI commands for remote setup of the MW8219A PIM Master and PIM Analyzer mode through the remote control of the Anritsu handheld product.

Instrument Messages and Errors lists reference, error, and warning messages.

Windowing describes windowing, which reduces side lobes by smoothing out the sharp transitions at the beginning and at the end of a frequency sweep.

Preset State Definitions describes preset states for Distance‑to‑PIM analysis.


Note	Images of measurement results and display screens that are shown in this manual are typical examples. Images on your instrument may differ.

Introduction

Anritsu has developed the PIM Master MW8219A to verify and troubleshoot Passive Inter‑Modulation (PIM). The PIM Master generates two high‑power tones, usually in the Tx band of interest. The Anritsu family of handheld RF instruments has a PIM Analyzer mode for controlling the PIM Master. These handheld instruments display and measure the third‑order, fifth‑order, or seventh‑order lower intermodulation product reflecting back from the DUT to the PIM Master.

Many of the Anritsu handheld instruments provide the Passive Inter‑Modulation (PIM) Analyzer to control the PIM Master MW8219A and take PIM measurements.


Note	Anritsu handheld instruments with a touch screen offer additional options for some features. You can touch a submenu key or a screen feature (such as the button for the Preset State entry in the DTP Parameters window shown in Figure: DTP Parameters Window).
