Warning
Laser radiation may be present at fiber-optic cable connectors and ports. This laser
radiation could present a nominal ocular hazard from either direct viewing or by diffuse
reflection. Do not view the emitted laser radiation directly or indirectly because damage
to the eye or permanent blindness may result.
Warning
This product may be supplied with a rechargeable battery. Only use batteries that are
designed for your equipment and that are supplied by Anritsu Company. Using an
incorrect battery could present a safety hazard and cause personal injury or damage to
the equipment and other loss. Batteries can potentially leak hazardous compounds into
the environment. These hazardous compounds present a risk of injury or loss due to
exposure. Anritsu Company recommends removing the battery for long-term storage of
the instrument and storing the battery in a leak-proof plastic container. Follow the
environmental storage requirements specified in the product technical data sheet and
always comply with your regional disposal regulations.
Warning
NEVER touch parts where the label shown on the left is attached. Such parts are hotter
than 55 degrees Celsius and you risk receiving a burn.
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
exposed, unpainted metal of 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 user guide covers the instrument overview, system functions, and other common features, along with a
brief guide to the basic measurement concepts and setups. Most of the instrument operations are covered in
specific chapters of this manual as listed below. Additionally, the MT2780A uses the MX280020A control
software installed on a PC or laptop for controlling the IQ Fiber Master hardware.
Note that whenever there is a new release of the control software, an Internet connection is required to verify
the hardware license of the IQ Fiber Master Analyzer that is connected to your PC or laptop. Once the initial
verification is confirmed the Internet connection is no longer required in performing necessary
measurements/analysis.
The IQ Fiber Master User Guide provides setup instructions for the connection and usage of the PIM over
CPRI and LTE RF over CPRI sensor and analyzer.
LTE RF over CPRI differs from PIM over CPRI in these ways:
•LTE RF over CPRI (Option 752): Provides full spectral analysis of CPRI IQ streams either in absolute or
relative frequency, and of LTE UL and DL signals. This function is analogous to a spectrum analyzer.
•PIM over CPRI (Option 754): (Requires options 752) Supports multiple PIM configurations while
measuring PIM power level. Provides distance-to-PIM (DTP). PIM over CPRI measures PIM against live
traffic to provide a truer picture of the impact of PIM at a cell site.
•PIM Analytics (Option 755): (Requires options 752 and 754) Provides, PIM vs. Time, PIM distribution,
PIM daily, and Heat Map data views. Reports include detailed pass/fail configuration check, long-term
(24-hour) monitoring, a pass/fail of each UL showing the external or internal nature of failures, and UL
and PIM spectra for each antenna branch.
Before You Begin
•Charge the instrument battery using the supplied battery charger until fully charged.
The following chapters provide information on the software user interface, such as instrument settings,
measurement features, and menu overviews, for the featured option:
•Chapter 2, “Instrument Overview” provides information about the physical instrument, connectors, and
other hardware interfaces.
•Chapter 3, “Making LTE RF over CPRI Measurements (Option 752)” provides information on the
software user interface, such as instrument settings, measurement features, and menu overviews, for
the spectrum analyzer.
•Chapter 4, “Making PIM-over-CPRI Measurements (Option 754)” provides information on the software
user interface, such as instrument settings, measurement features, and menu overviews, for the
real-time spectrum analyzer.
•Chapter 5, “PIM Analytics (Option 755)” provides information on the software user interface, such as
instrument settings, measurement features, and menu overviews, for the 5GNR analyzer.
Note The instrument may reboot when the battery charge level is low and external power is removed.
