MS2711A
Handheld Spectrum Analyzer
Spectrum Analysis – Anywhere, Anytime
2
The MS2711A Handheld Spectrum Analyzer provides the
“ultimate” in measurement flexibility for field environments
and applications requiring mobility. Unlike traditional spectrum analyzers, the MS2711A features a rugged, ultra-lightweight, battery-operated design that enables users to conduct spectrum analysis measurements – anywhere, anytime.
Providing complete freedom from AC/DC power requirements, the MS2711A enables you to locate, identify, record
and solve communication systems problems quickly and easily, without sacrificing measurement accuracy.
Whether you are installing, maintaining, or troubleshooting a
modern wireless communication system, the MS2711A provides exceptional performance combined with ease-of-use
and broad functionality – making it an ideal solution for engineers and technicians who conduct field measurements in
the 100 kHz to 3.0 GHz frequency range.
The Lightest Spectrum Analyzer Available
Weighing only 4.0 lbs. (1.8 kg), the MS2711A is the lightest
spectrum analyzer available.
Rugged and Reliable
Because the MS2711A handheld spectrum analyzer was
designed specifically for field environments, it can easily
withstand the day-to-day punishment of field use. Rugged
packaging also keeps the MS2711A performing in harsh
environments.
With its lightweight NiMH battery, the MS2711A operates
continuously for over two hours on a single charge. Built-in
energy conservation features allow battery life to be extended beyond an eight-hour workday. The MS2711A can also be
operated from a 12.5 Vdc source such as an AC-DC adapter
or automotive cigarette lighter adapter that also simultaneously charges the battery.
Easy-to-Use
Operation is straight-forward and driven by firmware that
simplifies the process of making measurements and interpreting the results shown on the large, high-resolution LCD
display. The menu-driven user interface is easy to use and
requires little training.
A full range of marker capabilities such as peak, center and
delta functions are also provided, giving users a faster and
more comprehensive measurement of displayed signals.
Limit lines simplify amplitude measurements, giving users the
capability to create quick, simple, pass/fail measurements.
Frequency, span and amplitude functions are easily configured for optimum performance. Used together with the Save
setup feature, these functions can help to make testing easier and faster for less experienced users.
Exceptional Performance
The MS2711A utilizes an advanced synthesizer-based
design that delivers accurate, reliable and repeatable measurements – anywhere, every time.
A broad range of functions coupled with narrow resolution
bandwidths down to 10 kHz make it ideal for finding the
source of interfering signals in modern wireless systems.
Powerful Trace Management
Users are able to store ten test setups along with 200 measurement traces internally in the unit’s non-volatile memory.
The stored data can be easily downloaded to a personal
computer (PC) or a printer via an RS-232 serial cable for further analysis. A notebook computer can be used with the RS232 interface for automated control and data collection in the
field. Additionally, a modem can be used for remote operation.

THE SMART SOLUTION FOR FIELD MEASUREMENTS
The MS2711A is perfect for radio communications agencies
needing to monitor signals and sources of interference in
field environments.
Power, frequency, occupied bandwidth, frequency deviation,
signal strength, AM/FM demodulation and modulation depth
measurements are easily executed with the MS2711A’s intu-
itive soft-key/hard-key user interface.
The MS2711A provides a broad range of testing capability
across a variety of field applications including:
• Detection of signal interference
• Monitoring of selected and unselected transmissions
• Detection of unlicensed transmitters
• Detection of undesired emissions
• Protection against concealed transmitters
• Coverage/Signal strength mapping
Interference
With the increased deployment of wireless technologies,
identifying the source of RF interference problems can be
very difficult. The MS2711A solves this problem by providing
the noise floor and phase noise performance necessary to
enable easy detection of signal interference. The units builtin AM/FM demodulation and
zero span capability, further
facilitates detection of signal
interference.
With the units RS-232 interface,
a notebook computer can be
used for automated control and
collection of interference data in
the field. A modem can also be
used for remote operation.
Antenna Alignment
The MS2711A is ideal for field alignment of small dish antennas. Simply tune to the frequency of interest and monitor
received signal strength until position is optimized.
Signal Mapping
Ideal for site surveys and other signal mapping applications,
the MS2711A can optimize placement of antennas and
access points in a WLAN or WPBX network. Identification of
potential in-band interference as well as transmitted signal
quality can be
easily performed
as the installer
moves about the
installation site.

Spurious Emissions
In-Band and Outof-Band spurious
emissions can
cause havoc
with Tx-Rx
communication
systems. Real-time
monitoring of spurious emissions from
a transmitter or
receiver can
uncover unwanted
signals before they
interfere with other
users of the radio
spectrum, rendering
your system noncompliant.
In-Band Spur Measurement
Out-of-Band Spur Measurement
Occupied Bandwidth
Monitoring of a transmitters occupied bandwidth enables the
user to determine if the transmitter is functioning properly.
The MS2711A provides Xdb Down and N% methods to
assist users in making transmitter occupied bandwidth measurements.
Occupied Bandwith Measurement
On-Site System Test
Featuring precision calibration, synthesizer-based design and
built in functions enable the MS2711A to optimize accuracy
and allow for easy verification of system compliance.
Convenient operating procedures, high sensitivity and excellent repeatability pinpoint the smallest RF performance degradation. Harmonic distortion, Occupied Bandwidth, Antenna-toAntenna isolation and potential interference problems can be
detected before small problems grow into big, costly, timeconsuming headaches and unwanted site downtime.

Anritsu MS2711A Software Tools is a database
and analysis tool for system maintenance. Test
data can be analyzed and compared to historical
performance. Up to 200 trace memory storage
locations can be downloaded with a single menu
selection.
MS2711A Software Tools run on Windows
®
,
Windows 95
®
, Windows 98®and Windows NT®.
The MS2711A Handheld Spectrum Analyzer
communicates to external controllers with an
RS-232 port. A serial null modem (RX-TX lines
are crossed, not straight through) cable is
standard with every MS2711A.
MS2711A data traces can be transferred to a
PC database with a single menu selection. Then
each trace / data record can be quickly annotated
with site, sector, feed, test type and other
information. Data is stored with each record, so it’s
easy to keep track of each Test Site’s data history.
Handy pull down menus minimize on-site typing
during installation.
If you’d rather minimize data entry, just type in the site
number or customer name to the database header file.
MS2711A Software Tools automatically store several critical
configurations and test data when it’s downloaded.
Tired of searching for a notebook full of
obsolete measurement data? When
you go to a site, your database goes
with you. MS2711A Software Tools is
intended for use as a maintenance
tool. You can add new data to an
existing database. Compare historical
measurements to current test data to
quickly pinpoint small changes in
performance. The database’s search
feature allows technicians to enter data
into any open field on the menu. The
search returns all trace data (“records”)
which fit the description. So, if you’d
like to see every trace measured by
“Phil B.” at site number “51”, just pulldown (or key-in) those selections
and click on the Search button.

RF Wattmeter/Power Monitor (Option 5)
A RF Wattmeter option is also available on the Anritsu MS2711A
HHSA. The MS2711A power monitor features precision, high
return loss (low SWR) detectors. The excellent impedance match
dramatically reduces the largest component of power measurement error, mismatch uncertainty. Display formats include
absolute power (dBM or Watts) and relative power (dB or %).
Built-in Auto-averaging automatically reduces the effects of noise.
Zeroing control allows optimum measurement accuracy at lower
power levels.
