1-2Instrument Description
The Spectrum Master is a synthesizer-based handheld spectrum analyzer that provides quick
and accurate measurement results. The instrument is designed for monitoring, measuring,
and analyzing signal environments. Measurements can easily be made by using the main
instrument functions: frequency, span, amplitude, and bandwidth. Dedicated keys for
common functions and a familiar calculator-type keypad are available for fast data entry.
Typical measurements include: in-band interference and transmit spectrum analysis, plus
cell site and 802.11a/b/g interference testing. Options are available for RF, advanced
demodulation, and over-the-air (OTA) measurement. A full range of marker capabilities (such
as peak, center, and delta functions) are provided for faster, more comprehensive analysis of
displayed signals. Upper and lower multi-segmented limit lines are available to create quick,
simple pass/fail measurements. A menu option provides for an audible alert when a limit
value is exceeded.
The bright daylight-viewable, high-resolution, color liquid crystal display (LCD) provides
easy viewing in a variety of lighting conditions. The Spectrum Master is capable of up to
3 hours of continuous operation from a fully charged battery and can be operated from a
12 VDC source, which simultaneously charges the battery.
The combination of a touch screen and keypad enables users to navigate menus with the
touch screen and enter numbers with the keypad.
Time and date stamping of measurement data is automatic. The internal memory provides
for the storage and recall of up to 1000 measurement setups and up to 1000 traces.
Measurements and setups can be stored in a USB flash drive or transferred to a PC by using
the included USB cable.
Not all after-market USB drives are compatible with the Spectrum Master. Many
drives come with a second partition that contains proprietary firmware. This
Note
partition must be removed. Only one partition is allowed. Refer to the individual
manufacturer for instructions on how to remove it. You may also try reformatting a

1-4Instrument Care and Preventive Maintenance
Instrument care and preventive maintenance consist of cleaning the unit and inspecting and
cleaning the RF connectors and all accessories. Clean the instrument with a soft, lint-free
cloth dampened with water or water and a mild cleaning solution.
CautionTo avoid damaging the display or case, do not use solvents or abrasive cleaners.
Connector Care
Clean the RF connectors and center pins with a cotton swab dampened with denatured
alcohol. Visually inspect the connectors. The fingers of the N(f) connectors and the pins of the
N(m) connectors should be unbroken and uniform in appearance. If you are unsure whether
the connectors are undamaged, gauge the connectors to confirm that the dimensions are
correct. Visually inspect the test port cable(s). The test port cable should be uniform in
appearance, and not stretched, kinked, dented, or broken.
To prevent damage to your instrument, do not use pliers or a plain wrench to tighten the
Type-N connectors. The recommended torque is 12 lbf·in to 15 lbf· in (1.36 N ·m to 1.70 N·m).
Inadequate torque settings can affect measurement accuracy. Over-tightening connectors can
damage the cable, the connector, the instrument, or all of these items.
Visually inspect connectors for general wear, cleanliness, and for damage such as bent pins or
connector rings. Repair or replace damaged connectors immediately. Dirty connectors can
limit the accuracy of your measurements. Damaged connectors can harm the instrument.
Connection of cables carrying an electrostatic potential, excess power, or excess voltage can
damage the connector, the instrument, or both.
Connecting Procedure
1. Carefully align the connectors. The male connector center pin must slip concentrically
into the contact fingers of the female connector.
2. Push connectors straight together. Do not twist or screw them together. A slight
resistance can usually be felt as the center conductors mate.
3. To tighten, turn the connector nut, not the connector body. Major damage can occur to
the center conductor and to the outer conductor if the connector body is twisted.
4. If you use a torque wrench, initially tighten by hand so that approximately 1/8 turn or
45 degrees of rotation remains for the final tightening with the torque wrench.
Relieve any side pressure on the connection (such as from long or heavy cables) in order
to assure consistent torque. Use an open-end wrench to keep the connector body from
turning while tightening with the torque wrench.
Do not over-torque the connector.
MS2720T UGPN: 10580-00340 Rev. N1-5
1-4 Instrument Care and Preventive MaintenanceGeneral Information
Disconnecting Procedure
1. If a wrench is needed, use an open-end wrench to keep the connector body from turning
while loosening with a second wrench.
2. Complete the disconnection by hand, turning only the connector nut.
3. Pull the connectors straight apart without twisting or bending.
ESD Caution
The Spectrum Master, like other high performance instruments, is susceptible to electrostatic
discharge (ESD) damage. Coaxial cables and antennas often build up a static charge, which
(if allowed to discharge by connecting directly to the instrument without discharging the
static charge) may damage the Spectrum Master input circuitry. Instrument operators must
be aware of the potential for ESD damage and take all necessary precautions.
Operators should exercise practices outlined within industry standards such as JEDEC-625
(EIA-625), MIL-HDBK-263, and MIL-STD-1686, which pertain to ESD and ESDS devices,
equipment, and practices. Because these apply to the Spectrum Master, it is recommended
that any static charges that may be present be dissipated before connecting coaxial cables or
antennas to the instrument. This may be as simple as temporarily attaching a short or load
device to the cable or antenna prior to attaching to the Spectrum Master. It is important to
remember that the operator may also carry a static charge that can cause damage. Following
the practices outlined in the above standards will ensure a safe environment for both
personnel and equipment.
RF Input Warning
The Anritsu Spectrum Master is a sensitive measuring instrument designed to measure low
power levels. Avoid damaging this sensitive circuitry by observing the maximum input levels
printed on the instrument connector labeling and specified in the product technical data
sheet.
Typical maximum input is +23 dBm (±50 VDC) and could be less if additional features, such
as a preamplifier, are in use. Be sure to review the product technical data sheet or Anritsu
website for recommended components and accessories that can help you protect your
instrument. These include a variety of adapters, attenuators, filters, and RF power detection
accessories.

Chapter 3 — Initial Startup
3-1Introduction
This chapter gives a brief overview of the Anritsu MS2720T Spectrum Master and is intended
to assist you in your first use of the instrument. The purpose of this chapter is to provide a
starting point for making basic measurement setups. This chapter describes general
instrument setup, including: instrument mode, frequency, bandwidth, amplitude, span, limit
lines, and markers. After measurements are taken, refer to “Managing Files” on page 4-1 for
a description of saving, recalling, and deleting measurement files. For more detailed
information about specific measurements, refer to the measurement descriptions in the
measurement guides for the specific instrument mode and analyzer technology (such as
Spectrum Analyzer, WiMAX, or 3GPP). Refer to Appendix A, “Related Documents”, for a list of
these measurement guides and their Anritsu part numbers.
The Spectrum Analyzer Measurement Guide includes sections that describe resolution
bandwidth, video bandwidth, sweep, and attenuator functions. For example, in the
Spectrum Master, Resolution Bandwidth is determined by the intermediate frequency (IF)
filter bandwidth. The spectrum analyzer traces the shape of the IF filter as it tunes past a
signal. If more than one IF filter is used in a spectrum analyzer, then the narrowest one
dominates and is considered the resolution bandwidth.

GPS
6-1Introduction
The Spectrum Master MS2720T is available with a built-in GPS receiver feature (Option 31)
that can provide latitude, longitude, altitude, and UTC timing information. This option also
enhances frequency reference oscillator accuracy in the spectrum analyzer mode. When GPS
is actively locked to satellites, this information is saved with all saved measurements and can
be displayed with Master Software Tools. No accuracy specifications apply if no GPS
satellites are acquired.
The Spectrum Master Technical Data Sheet provides a list of the options and

4. When the GPS receiver is tracking at least four satellites, the GPS icon changes to
green. Latitude and longitude information is displayed in the title bar at the top of the
display. Acquiring satellites may take as long as three minutes.
Figure 6-2.GPS Icon, Green
5. Press the GPS Info submenu key to display the following information:
• Tracked satellites
• Latitude and longitude
• Altitude
• UTC timing information
• Fix available
• Almanac complete
• Antenna and receiver status
• GPS antenna voltage and current
Refer to “GPS Menu” on page 6-4 for details on the above GPS Info items.
After GPS location fix is attained, the internal reference oscillator begins to correct its
frequency to match the GPS standard. After the internal frequency is adjusted to match the
GPS standard, the status is indicated by “GPS High Accuracy” showing in the Status menu,
which is displayed on the left side of the measurement display. When the GPS feature is not
enabled, the reference source displays either “Internal Standard Accuracy” or a user-selected
external reference frequency in the Status menu.
Within three minutes of satellite acquisition, the reference oscillator will have an accuracy of
better than 25 ppb (parts per billion). The correction factor applied to the internal OCXO
allows the instrument to maintain GPS frequency accuracy for three days at better than
50 ppb, even when the instrument is obstructed from receiving signals from the GPS
satellites.
In order to acquire data from the GPS satellites, you must have line-of-sight to the satellites,
or the antenna must be placed outside with no obstructions.
If no GPS is connected for at least three days, the Frequency Reference annotation reads Int Std Accy.
When GPS is connected, with a fix, and the tuning process has completed (which may take a
few minutes), the Frequency Reference annotation shows GPS Hi Accy. If GPS is
subsequently lost (for example, GPS is turned off, disconnected, or there is no signal due to
physical obstruction), the instrument goes back to Int Hi Accy after a few moments. If GPS
remains disconnected for three consecutive days, whether the instrument is on or off, the
instrument reverts to Int Std Accy.

Chapter 8 — Web Remote Control
8-1Introduction
Web Remote Control capabilities are embedded in the Spectrum Master, providing full
instrument control through an HTML-5 compatible browser. The ability to remotely monitor
and control the instrument from the ground or desk enhances operator safety and efficiency
when conditions make it unsafe or impractical to be close to the instrument. Login passwords
can be used to allow access to authorized users only.
A remote connection terminates when the user logs out or closes the browser, or when the
session time requested at login expires. To prevent multi-user conflicts, only one connection is
permitted at a time. A second user who tries to log in will see a message indicating the
instrument is currently reserved by another client, with the time remaining in their session.
While only one user can have control of the instrument, multiple users can view the same
instrument using a desktop sharing application.
8-2Setup
You can connect one or more instruments to any computer with HTML-5 compatible browser.
Anritsu strongly recommends using Google Chrome, as other browsers do not fully support
HTML-5. The control device may be a laptop, a desktop computer, or a mobile device,
including a wide range of tablets and smart phones running Android or iOS operating
systems. Note that you cannot download files to an iOS device, for lack of a user-accessible file
system in this environment.
Physical connection is established from the instrument’s Ethernet port directly to the
computer, or to a LAN or a portable Wi-Fi router such as the ZyXEL MWR102 Portable
Router.
