Safety-2 PN: 10580-00283 Rev. D MW8208A, MW8209A, MW8219A MM

For Safety

Warning Always refer to the operation manual when working near locations at which

the alert mark, shown on the left, is attached. If the operation, etc., is

performed without heeding the advice in the operation manual, there is a

risk of personal injury. In addition, the equipment performance may be

reduced.

Moreover, this alert mark is sometimes used with other marks and

descriptions indicating other dangers.

Warning

When supplying power to this equipment, connect the accessory 3-pin

power cord to a 3-pin grounded power outlet. If a grounded 3-pin outlet is

not available, use a conversion adapter and ground the green wire, or

connect the frame ground on the rear panel of the equipment to ground. If

power is supplied without grounding the equipment, there is a risk of

receiving a severe or fatal electric shock.

Warning This equipment can not be repaired by the operator. Do not attempt to

remove the equipment covers or to disassemble internal components.

Only qualified service technicians with a knowledge of electrical fire and

shock hazards should service this equipment. There are high-voltage parts

in this equipment presenting a risk of severe injury or fatal electric shock to

untrained personnel. In addition, there is a risk of damage to precision

components.

Warning

Use two or more people to lift and move this equipment, or use an

equipment cart. There is a risk of back injury if this equipment is lifted by

one person.

Caution

Electrostatic Discharge (ESD) can damage the highly sensitive circuits in

the instrument. ESD is most likely to occur as test devices are being

connected to, or disconnected from, the instrument’s front and rear panel

ports and connectors. You can protect the instrument and test devices by

wearing a static-discharge wristband. Alternatively, you can ground

yourself to discharge any static charge by touching the outer chassis of the

grounded instrument before touching the instrument’s front and rear panel

ports and connectors. Avoid touching the test port center conductors

unless you are properly grounded and have eliminated the possibility of

static discharge.

Repair of damage that is found to be caused by electrostatic discharge is

not covered under warranty.

Chapter 1 — General Information

1-1 Introduction

This manual provides maintenance instructions for Anritsu PIM Master models MW8208A, MW8209A and

MW8219A.

The information includes:

•Chapter 1, “General Information”

•Chapter 2, “PIM Analyzer Verification”

•Chapter 3, “Troubleshooting”

•Appendix A, “Test Records”

Throughout this manual, the following terms apply:

•PIM Master refers to models MW8208A, MW8209A and MW8219A.

•Controller refers to any of the Anritsu handheld RF and microwave instruments that are capable of

controlling the PIM Master. Refer to the PIM Master Product Brochure (part number: 11410-00546) for

specifications and a list of handheld instrument models that support the Passive Inter-Modulation (PIM)

Analyzer and the Distance-to-PIM™ Analyzer.

Familiarity with the basic operation of the front panel keys (for example, how to change measurement mode,

preset the instrument, or the meaning of submenu button or main menu button) is assumed. Refer to the

PIM Master User Guide (Anritsu part number: 10580-00280).

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.

Ensure that all antennas under test are placed so that no personnel are exposed to RF levels

that exceed the maximum allowable exposure.

Note

Anritsu recommends that you make a copy of the blank test records to document the measurements

each time a Performance Verification is performed. Continuing to document this process each time it

is performed provides a detailed history of instrument performance, which allows you to observe

trends.

1-2 Product Description Chapter 1 — General Information

1-2 PN: 10580-00283 Rev. D MW8208A, MW8209A, MW8219A MM

1-2 Product Description

The MW8208A, MW8209A, and MW8219A PIM Master models are portable passive inter-modulation

analyzers featuring precise performance for the GSM(850 MHz), E-GSM (900 MHz), PCS, and AWS cellular

frequency bands. They are designed to accurately determine if receiver interference at a cell site is due to an

inter-modulation product of two or more transmit frequencies, also known as passive inter-modulation (PIM).

The PIM Master generates two high-power tones in the transmit band of a base station, and the Anritsu family

of PIM Master compatible handheld RF instruments (refer to Section 1-1) measure the third-order, fifth-order,

or seventh-order inter-modulation products in the receive band coming back down the same cable. The current

standard for PIM testing offers a well-known system using two primary carriers and a calculated resulting

PIM frequency, which is measured with a spectrum analyzer. This provides a measurement of the overall

linearity of the antenna system and the surrounding environment. PIM Analyzer Option 0419 for select models

of the Anritsu family of RF handheld instruments is no longer required because the PIM Analyzer mode will be

already available (ss a standard feature) to the end user with the handheld instrument.

In addition to PIM testing, the PIM Master also has Distance-to-PIM™ (DTP) Analyzer capability. 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.

The Distance-to-PIM™ Analyzer features are displayed in the relative menus. The choice between PIM

analysis and Distance-to-PIM™ analysis is made in the Measurements menu of the Anritsu handheld

instrument.
