Safety Symbols
To prevent the risk of personal injury or loss related to equipment malfunction, Anritsu Company uses the
following symbols to indicate safety-related information. For your own safety, please read the information
carefully before operating the equipment.
Symbols Used in Manuals
Safety Symbols Used on Equipment and in Manuals
The following safety symbols are used inside or on the equipment near operation locations to provide
information about safety items and operation precautions. Ensure that you clearly understand the meanings of
the symbols and take the necessary precautions before operating the equipment. Some or all of the following
five symbols may or may not be used on all Anritsu equipment. In addition, there may be other labels attached
to products that are not shown in the diagrams in this manual.
Danger
This indicates a risk from a very dangerous condition or procedure that could result in
serious injury or death and possible loss related to equipment malfunction. Follow all
precautions and procedures to minimize this risk.
Warning This indicates a risk from a hazardous condition or procedure that could result in
light-to-severe injury or loss related to equipment malfunction. Follow all precautions
and procedures to minimize this risk.
Caution
This indicates a risk from a hazardous procedure that could result in loss related to
equipment malfunction. Follow all precautions and procedures to minimize this risk.
This indicates a prohibited operation. The prohibited operation is indicated symbolically
in or near the barred circle.
This indicates a compulsory safety precaution. The required operation is indicated
symbolically in or near the circle.
This indicates a warning or caution. The contents are indicated symbolically in or near
the triangle.
This indicates a note. The contents are described in the box.
These indicate that the marked part should be recycled.

Safety-2 PN: 10580-00433 Rev. D MS276xA 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.
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.
Warning This equipment is supplied with a rechargeable battery that could
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
data sheet.

Chapter 1 — General Information
1-1 Introduction
This manual provides maintenance instructions for the Anritsu MS2760A and MS2762A Spectrum Masters.
When referring to both models MS276xA will be used. This manual includes:
•General information, including:
•List of necessary test equipment to perform verification testing (Table 1-1)
•Replaceable parts list (Table 1-2)
•Performance verification procedures in Chapter 2, “Spectrum Analyzer Verification”
•Troubleshooting procedures in Chapter 3, “Troubleshooting”
•Blank test records are included in Appendix A. Copy the blank test records and use them to record
measured values. These test records form a record of the performance of the MS276xA. Anritsu
recommends making 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 provides a
detailed history of the instrument’s performance, allowing trends to be observed.
Familiarity with the basic operation of the MS276xA using the GUI software is assumed, for example, how to
preset the instrument and set frequency, span, and RBW settings.

PASS/FAIL Determination for Instrument Key Parameter Performance Tests
Figure 2-1 shows the rule that is used to determine the pass/fail status of test results that are associated with
warranted specifications.
The measurement uncertainty listed in each test record includes the best estimate of the errors contributed by
the measurement, test equipment, standards, and other correction factors (for example, calibration factors and
mismatch error) based on the suggested equipment, the equipment setup, and the prescribed test procedure.
Most of the uncertainties are type-B per ISO/IEC Guide 98-3, Guide to the Expression of Uncertainty in
Measurement (GUM).
