Spectrum Master™ MS2720T Spectrum Analyzer Introduction
Overview
Introduction
Operating convenience is of paramount importance when
equipment is used in the field.
To achieve greater operating convenience several parameters
are tied to related parameters. The input attenuation value
by default is tied to the reference level, reducing the number
of parameters a field technician may have to set. Also the
RBW/VBW ratio and the span/RBW ratio default to values that
meet most user’s needs but can be changed by users to meet
specific needs, further easing the technician’s burden and
reducing the chances of errors.
Measurement flexibility is important for lab use. Resolution
bandwidth and video bandwidth can be independently set
to meet a user’s measurement needs. In addition the input
attenuator value can be set by the user and the preamplifier
can be turned on or off as needed.
For maximum flexibility, sweeping can be set to free run, or to
do a single sweep. In zero span, the sweep can free run, be set
to trigger when a signal meets or exceeds a certain power level
or it can be externally triggered. The span can be set anywhere
from 10 Hz to 9, 13, 20, 32 or 43 GHz in addition to zero span.

one to meet virtually every measurement need. In addition to
spectrum analysis a user can select optional capabilities and
analyzers including:
• High Accuracy Power Meter
• Interference Analyzer
• Channel Scanner
• 30 MHz Wide Zero-Span IF Output at 140 MHz
• GPS Receiver
• Internal Atomic Clock
• Increase frequency accuracy, geo-tag data collection
• Secure data operation
• 3GPP Signal Analyzers

• GSM, W-CDMA/HSPA+, TD-SCDMA/HSPA+
The MS2720T has a touch menu with user-defined shortcuts
• 3GPP2 Signal Analyzers CDMA and EV-DO
• IEEE 802.16 Signal Analyzers
• Fixed WiMAX, Mobile WiMAX
• PIM Analyzer
• Coverage Mapping
Fast Sweep
The new fast sweep mode has the paradigm busting capability
to set resolution bandwidth from 10 MHz to 30 kHz with very
little effect on sweep speed. The sweep speed with a 30 kHz
bandwidth is about the same as it is when using a 10 MHz
RBW. You can now select your sensitivity without the need for
long sweep times.
Burst Detect
Being able to reliably detect bursty signals is vital in the efforts
to find intermittent or bursty emitters. Using burst detect,
emitters as narrow as 200 µs can be captured the first time,
every time.
Touch Screen
The MS2720T includes a touch screen user interface. On
the touch screen menu the user can add shortcut buttons
for any menu button or file on the instrument. Using this
capability, a setup file can be recalled with a single press of
the touch screen.
The MS2720T is Anritsu’s fastest sweeping
handheld spectrum analyzer
Tracking Generators
The 9 GHz, 13 GHz and 20 GHz instruments can be equipped
with a tracking generator that covers 9 kHz to the top
frequencies of the instruments. Power output is leveled and
adjustable from 0 dBm to -40 dBm in 0.1 dB steps over the full
temperature range of the instrument: -10 °C to +55 °C.
Finding Signals
Hidden transmitters can be challenging to find, especially
if they are operating at frequencies very near a high power
transmitter. With Spectrum Master you get the powerful
combination of low phase noise, wide RBW range down to 1 Hz,
and wide dynamic range. Even if a transmitter is hidden within
10 Hz of a strong AM carrier, it can be seen with Spectrum
Master. The trace display choices and detector choices combine
to make it easy to detect intermittent signals in the presence of
steady signals and burst detect makes direction finding bursty
signals easier than it has ever been.
Low Phase Noise and wide dynamic range leaves
no place to hide a transmitter

Overview (continued)
Interference Analysis
Interference is an ever-growing concern for anyone who
transmits a signal over the air. Spectrum Master is ideally
suited for tracking down interference with its great lineup of
interference measuring capability. Spectrogram shows you
what is happening over time so spotting intermittent interferers
becomes easy. Signal strength measurement, coupled with a
directional antenna, makes finding rogue transmitters much
easier. You can even get an audio indicator of the strength of
the signal so you can find the transmitter without having to
watch the display.
Storage
Measurements, limit lines, JPEG screen shots and setup
files can be stored internally or to an external USB memory.
There is sufficient internal memory to store thousands of
spectrum analyzer traces. By using external USB memory,
tens of thousands of measurements, limit lines and setup files
or hundreds of JPEG screen shots can be saved and easily
transferred onto a computer.
Spectrogram in Interference Analysis option 25
Smart Measurements
The Spectrum Master family has dedicated routines for
one-button measurements of field strength, channel power,
occupied bandwidth, Adjacent Channel Power Ratio (ACPR) and
C/I. These are increasingly critical measurements for today’s
wireless communication systems. The simple interface for
these complex measurements significantly reduces test time
and increases analyzer usability.
Field Strength
By using an antenna for which antenna factors are known,
the instrument calculates the field strength either in dBm/m2,
dBV/m, volts/meter, Watts/m2, Watts/cm2, dBw/m2, A/m, or
dbA/m.
Occupied Bandwidth
This measurement determines the amount of spectrum used
by a modulated signal. You can choose between two different
methods of determining bandwidth: the percent of power
method or the “x” dB down method, where “x” can be from
1 dB to 100 dB down the skirts of the signal.
Built-in Occupied Bandwidth measurement
Channel Power
This smart measurement delivers the total power integrated
across a specified channel bandwidth. The user can enter
the center frequency and the channel width or it can be
automatically set by selecting a signal standard and channel
number in the frequency menu.
Adjacent Channel Power Ratio
A common transmitter measurement is that of adjacent
channel leakage power. This is the ratio of the amount of
leakage power in an adjacent channel to the total transmitted
power in the main channel, and is used to replace the
traditional two-tone intermodulation distortion (IMD) test for
system non-linear behavior.
The result of an ACPR measurement can be expressed either
as a power ratio or a power density. In order to calculate
the upper and lower adjacent channel values, the Spectrum
Master allows the adjustment of four parameters to meet
specific measurement needs: main channel center frequency,
measurement channel bandwidth, adjacent channel bandwidth
and channel spacing. When an air interface standard is
specified in the Spectrum Master, all these values are
automatically set to the normal values for that standard.
Adjacent Channel Power Ratio (ACPR) is also built-in

Spectrum Master™ MS2720T Spectrum Analyzer Introduction
Overview (continued)
Carrier to Interference (C/I) Measurement
As more 802.11 access points are installed, there is an
increasing level of interference in the 2.4 GHz and 5.8 GHz
bands occupied by this service and other devices such as
cordless telephones. This measurement capability makes it
simple for an access point installer to determine if the level
of interference is sufficient to cause difficulty for users in the
intended service area, and can show the need to change to
another access channel. The wide frequency coverage of the
Spectrum Master makes this the only spectrum analyzer you
need to install and maintain 802.11a, 802.11b and 802.11g
wireless networks.
Emission Mask
A limit line can be used as a pass/fail emission mask. A table
shows for each segment of the emission mask if the signal
passed or failed for that segment. Peak markers can be turned
on to automatically show the highest signal in each segment of
the mask.
Emission Mask measurement shows pass/fail for every segment
AM/FM/SSB Demodulation
AM, narrowband FM, 25 kHz, 12.5 kHz and 6.25 kHz,
wideband FM and single sideband (both upper and lower) can
be demodulated to audio, all with proper de-emphasis. The
demodulated audio can be heard through the built-in speaker
or through a headset plugged into the 3.5 mm headset jack.
The signal to be demodulated can be anywhere in the
frequency range of the instrument and does not have to be
within the current sweep range of the instrument, nor is it tied
to a marker. The demodulation bandwidth is automatically set
for each modulation format to assure ease of operation. There
is no need to fuss with RBW and video filters to get proper
demodulation.
GPS (Option 31)
With GPS Option 31 the frequency accuracy is 25 ppb (parts
per billion) after achieving a GPS lock. After the GPS antenna
is disconnected, accuracy is maintained at 50 ppb or better for
up to three days. Also all saved measurements are GPS tagged
for exporting to maps when the instrument has a GPS fix. Two
GPS antennas are available, 2000-1528-R with a 15 foot cable
and 2000-1652-R with a 1 foot cable. Order the antenna or
antennas that meet your needs.

Power Meter
High Accuracy Power Meter (Option 0019)
Power Meter Modes
The Spectrum Master offers an optional
High Accuracy Power Meter (option 19)
that uses external power sensors.
USB Power Sensors
Setting the transmitter output power of
a base station properly is critical to the
overall operation of a wireless network.
A 1.5 dB change in power levels means a
15% change in coverage area. Too much
power means overlapping coverage which
translates into cell-to-cell self-interference.
Too little power, too little coverage, creates
island cells with non-overlapping cell
sites and reduced in-building coverage.
High or low values will cause dead zones/
dropped calls, lower data rates/reduced
capacity near cell edges, and cell loading
imbalances along with blocked calls.
High Accuracy Power Meter (Option 19)
For the most accurate power measurement
requirements select the high accuracy
measurement option with a choice of
sensors with:
• Frequency ranges:
10 MHz to 26 GHz
• Power ranges:
–40 dBm to +51.76 dBm
• Measurement uncertainties:
≤ ± 0.18 dB
High Accuracy Power, option 19, uses USB power
sensors for accurate measurements up to 26 GHz
These sensors enable users to make
accurate measurements for CW
and digitally modulated signals for
2G/3G and 4G wireless networks.
The power sensor easily connects to the
Spectrum Master via a USB A/mini-B
cable. An additional benefit of using the
USB connection is that a separate DC
supply (or battery) is not needed since
the necessary power is supplied by the
USB port.
PC Power Meter
These power sensors can be used with a
PC running Microsoft Windows® via USB.
They come with PowerXpert™ application,
a data analysis and control software. The
application has abundant features, such as
data logging, power versus time graph, big
numerical display, and many more, that
enable quick and accurate measurements.

Outdoor Mapping
With a GPS antenna connected to the
instrument and a valid GPS signal, the
instrument monitors RSSI and ACPR levels
automatically. Using a map created with
Map Master, the instrument displays maps,
the location of the measurement, and a
special color code for the power level.
The refresh rate can be set up in time
(1 sec, minimum) or distance. The overall
amplitude accuracy coupled with the GPS
update rate ensures accurate and reliable
mapping results.
Indoor Mapping
When there is no GPS signal valid, the
Spectrum Master uses a start-walk-stop
approach to record RSSI and ACPR levels.
You can set the update rate, start location,
and end location and the interpolated
points will be displayed on the map.
Export KML Files
Save files as KML or JPEG. Open KML files
with Google Earth™. When opening up

Introduction to Wireless Measurements
Wireless Measurements
The Spectrum Master features
Wireless Measurements for the major
wireless standards around the world.
The Wireless Measurements are designed
to test and verify the following base
station transmitter performance:
• RF Quality
• Modulation Quality
• Downlink Coverage
LTE signal
The goal of these tests is to improve
the Key Performance Indicators (KPIs)
associated with:
• Call Drop Rate
• Call Block Rate
• Call Denial Rate
WiMAX signal
By understanding which test to perform
on the Spectrum Master when the KPIs
degrade to an unacceptable level, a
technician can troubleshoot down to
the Field Replacement Unit (FRU) in the
base station’s transmitter chain. This
will minimize the problem of costly no
trouble founds (NTF) associated with card
swapping. This will allow you to have a
lower inventory of spare parts as they are
used more efficiently.
Troubleshooting Guides
The screen shots on this page are all
measurements made over-the-air with
the MS2720T on commercial base stations
carrying live traffic. To understand
when, where, how, and why you make
these measurements Anritsu publishes
Troubleshooting Guides which explain for
each measurement the:
• Guidelines for a good measurement
• Consequences of a poor measurement
• Common faults in a base station
Troubleshooting guide
These Troubleshooting Guides for
Base Stations are one-page each per
Signal Analyzer. They are printed on tearresistant and smudge-resistant paper and
are designed to fit in the soft case of the
instrument for easy reference in the field.
They are complimentary and their part

• RF Measurements
RF Measurement – Occupied Bandwidth
Excessive occupied bandwidth can create interference
with adjacent channels or be a sign of poor signal
quality, leading to dropped calls.
The goal of these measurements is
to increase data rate and capacity by
accurate power settings, ensuring low
out-of-channel emissions, and good signal
quality. These attributes help to create a
low dropped call rate, a low blocked call
rate, and a good customer experience.
Cell site technicians or RF engineers can
make measurements Over-the-Air (OTA)
to spot-check a transmitter’s coverage
and signal quality without taking the cell
site off-line. When the OTA test results
are ambiguous one can directly connect
to the base station to check the signal
quality and transmitter power.
Demodulation – Error Vector Magnitude (EVM)
This is the single most important signal quality
measurement. Poor EVM leads to dropped calls, low
data rate, low sector capacity, and blocked calls.
For easy identification of which cell you
are measuring the Base Station Identity
Code (BSIC) gives the base station id,
the Network Color Code (NCC) identifies
the owner of the network, and the Base
Station Color Code (BCC) provides the
sector information.
Carrier-to-Interference (C/I)
C/I indicates the quality of the received
signal. It also can be used to identify
areas of poor signal quality. Low C/I
ratios will cause coverage issues including
dropped calls, blocked calls, and other
handset reception problems.
RF Measurement – Average Burst Power
High or low values will create larger areas of cell-tocell interference and create lower data rates near cell
edges. Low values create dropouts and dead zones.
Phase Error
Phase Error is a measure of the phase
difference between an ideal and actual
GMSK modulated voice signal. High phase
error leads to dropped calls, blocked calls,
and missed handoffs.
Origin Offset
Origin Offset is a measure of the DC
power leaking through local oscillators and
mixers. A high Origin Offset will worsen
EVM and Phase Error measurements and
create higher dropped call rates.
Pass/Fail Test
Set up common test limits, or sets of limits, for
each instrument. Inconsistent settings between base
stations, leads to inconsistent network behavior.
Occupied Bandwidth
• Demodulation
Power versus Time (Slot and Frame)
Power versus Time (Slot and Frame)
should be used if the GSM base station
is setup to turn RF power off between
timeslots. When used OTA, this
measurement can also spot GSM signals
from other cells. Violations of the mask
create dropped calls, low capacity, and
small service area issues.

W-CDMA/HSPA+ Signal Analyzers
The Spectrum Master features three
W-CDMA/HSPA+ measurement situations:
• RF Measurements
• Demodulation
• Over-the Air Measurements (OTA)
RF Measurements – Spectral Emissions Mask
The 3GPP spectral emission mask is displayed. Failing
this test leads to interference with neighboring carriers,
legal liability, and low signal quality.
Demodulation – Error Vector Magnitude (EVM)
This is the single most important signal quality
measurement. Poor EVM leads to dropped calls, low
data rate, low sector capacity, and blocked calls.
The goal of these measurements is
to increase data rate and capacity by
accurate power settings, ensuring low
out-of-channel emissions, and good signal
quality. These attributes help to create a
low dropped call rate, a low blocked call
rate, and a good customer experience.
Cell site technicians or RF engineers can
make measurements Over-the-Air (OTA)
to spot-check a transmitter’s coverage
and signal quality without taking the Node
B off-line. When the OTA test results are
ambiguous one can directly connect to the
base station to check the signal quality
and transmitter power.
Frequency Error
Frequency Error is a check to see that
the carrier frequency is precisely set.
The Spectrum Master can accurately
measure Carrier Frequency Error OTA if
the instrument is GPS enabled or in GPS
holdover. Calls will drop when mobiles
travel at higher speed. In some cases,
cell phones cannot hand off into, or
out of the cell.
Peak Code Domain Error (PCDE)
Peak Code Domain Error is a measure of
the errors between one code channel and
another. High PCDE causes dropped calls,
low signal quality, low data rate, low sector
capacity, and blocked calls.
Over-the-Air Measurements – Scrambling Codes
Too many strong sectors at the same location creates
pilot pollution. This leads to low data rate, low
capacity, and excessive soft handoffs.
Multipath
Multipath measurements show how
many, how long, and how strong the
various radio signal paths are. Multipath
signals outside tolerances set by the
cell phone or other UE devices become
interference. The primary issue is
co-channel interference leading to
dropped calls and low data rates.
Pass/Fail Mode
The Spectrum Master stores the five test
models covering all eleven test scenarios
specified in the 3GPP specification
(TS 25.141) for testing base station
performance and recalls these models for
quick easy measurements.
Pass/Fail Test
Set up common test limits, or sets of limits, for
each instrument. Inconsistent settings between base
stations, leads to inconsistent network behavior.

• RF Measurements
• Demodulation
• Over-the Air Measurements (OTA)
RF Measurements – Spectral Emissions Mask
The 3GPP spectral emission mask is displayed. Failing
this test leads to interference with neighboring carriers,
legal liability, and low signal quality.
Modulation Quality – EVM
High or low values will create larger areas of cell-tocell interference and create lower data rates near cell
edges. Low values affect in-building coverage.
The goal of these measurements is
to increase data rate and capacity by
accurate power settings, ensuring low
out-of-channel emissions, and good signal

and signal quality without taking the cell
site off-line. When the OTA test results are
ambiguous one can directly connect to the
base station to check the signal quality
and transmitter power.
Error Vector Magnitude (EVM) is the ratio
of errors, or distortions, in the actual
signal, compared to a perfect signal. EVM
faults will result in poor signal quality to
all user equipment. In turn, this will result
in extended hand off time, lower sector
capacity, and lower data rates, increasing
dropped and blocked calls.
Peak Code Domain Error (Peak CDE)
Peak CDE is the EVM of the worst code.
Code Domain displays show the traffic
in a specific time slot. Peak CDE faults
will result in poor signal quality to all
user equipment. In turn, this will result
in extended hand off time, lower sector
capacity, and lower data rates.
OTA Tau Scanner Ec/Io
Ec/Io faults indicate excessive or
inadequate coverage and lead to low
capacity, low data rates, extended
handoffs, and excessive call drops.
Over-the-Air Measurements – Sync Signal Power
Check for uneven amplitude of sub-carriers. Data will
be less reliable on weak sub-carriers, creating a lower
overall data rate.
DwPTS OTA Power Mapping
DwPTS OTA Power when added to
Ec/Io gives the absolute sync code power
which is often proportional to PCCPCH
(pilot) power. Use this to check and plot
coverage with GPS. Coverage plots can
be downloaded to PC based mapping
programs for later analysis. Poor readings
will lead to low capacity, low data rates,
excessive call drops and call blocking.

Spectrum Master™ MS2720T Spectrum Analyzer Features
LTE FDD/TDD Measurements (Option 883)
LTE FDD/TDD Signal Measurements
The Spectrum Master features three LTE
measurement modes:
• RF Measurements
• Modulation Measurements
• Over-the Air Measurements (OTA)
Modulation Quality – Power vs. Resource Block
A high utilization of the Resource Blocks would indicate
a cell site in nearing overload and it may be appropriate to start planning for additional capacity.
The goal of these measurements is
to increase data rate and capacity by
accurate power settings, ensuring low
out-of-channel emissions, and good signal
quality. These attributes help to create a
low dropped call rate, a low blocked call
rate, and a good customer experience.
Cell site technicians or RF engineers can
make measurements Over-the-Air (OTA)
to spot-check a transmitter’s coverage
and signal quality without taking the cell
site off-line. When the OTA test results are
ambiguous one can directly connect to the
base station to check the signal quality
and transmitter power.
Adjacent Channel Leakage Ratio (ACLR)
Modulation Quality – Control Channels
High values will create larger areas of cell-to-cell
interference and create lower data rates near cell
edges. Low values affect in-building coverage.
Adjacent Channel Leakage Ratio (ACLR)
measures how much BTS signal gets into
neighboring RF channels. ACLR checks the
closest (adjacent) and the second closest
(alternate) channels. Poor ACLR can lead
to interference with adjacent carriers
and legal liability. It also can indicate
poor signal quality which leads to low
throughput.
Cell ID (Sector ID, Group ID)
Cell ID indicates which base station is
being measured OTA. The strongest base
station at your current location is selected
for measurement. Wrong values for Cell ID
lead to inability to register. If the cause is
excessive overlapping coverage, it also will
lead to poor EVM and low data rates.
Pass/Fail Test
Over-the-Air Measurements – Tx Test
By looking at the reference signals of MIMO antennas
one can determine if MIMO is working properly. If the
delta power is too large, there is an issue.
Set up common test limits, or sets of
limits, for each instrument. Inconsistent
settings between base stations, leads to
inconsistent network behavior.
EVM
High values will create larger areas of
cell-to-cell interference and create lower
data rates near cell edges.
Mapping
Over-the-Air On-screen Mapping
With Map Master™ import map area on instrument
screen to drive test downlink coverage of S-SS Power,
RSRP, RSRQ, or SINR.
On-screen mapping allows field technicians
to quickly determine the downlink
coverage quality in a given geographic
location. Plot S-SS Power, RSRP, RSRQ or
SINR with five user definable thresholds.
All parameters are collected for the
three strongest signals and can be saved
as *.kml and *.mtd (tab delimited)
for importing to third party mapping
programs for further analysis.

Spectrum Master™ MS2720T Spectrum Analyzer Features
CDMA/EV-DO Measurements (Option 884)
CDMA Measurements
The Spectrum Master features three
CDMA measurement modes:
• RF Measurements
• Demodulation
• Over-the Air Measurements (OTA)
RF Measurements – Spectral Emissions Mask
The 3GPP2 spectral emission mask is displayed. Failing
this test leads to interference with neighboring carriers,
legal liability, and low signal quality.
Modulation Quality – EVM
High or low values will create larger areas of cell-tocell interference and create lower data rates near cell
edges. Low values affect in-building coverage.
The goal of these measurements is
to increase data rate and capacity by
accurate power settings, ensuring low
out-of-channel emissions, and good signal
quality. These attributes help to create a
low dropped call rate, a low blocked call
rate, and a good customer experience.
Cell site technicians or RF engineers can
make measurements Over-the-Air (OTA)
to spot-check a transmitter’s coverage
and signal quality without taking the cell
site off-line. When the OTA test results are
ambiguous one can directly connect to the
base station to check the signal quality
and transmitter power.
Adjacent Channel Power Ratio (ACPR)
ACPR measures how much of the carrier
gets into neighboring RF channels. ACPR,
and multi-channel ACPR, check the closest
(adjacent) and second closest (alternate)
RF channels for single and multicarrier
signals. High ACPR will create interference
for neighboring carriers. This is also an
indication of low signal quality and low
capacity, which can lead to blocked calls.
RMS Phase Error
RMS Phase Error is a measure of signal
distortion caused by frequency instability.
Any changes in the reference frequency
or the radio’s internal local oscillators will
cause problems with phase error. A high
reading will cause dropped calls, low signal
quality, low data rate, low sector capacity,
and blocked calls.
Over-the-Air Measurements – Sync Signal Power
Check for uneven amplitude of sub-carriers. Data will
be less reliable on weak sub-carriers, creating a lower
overall data rate.
Noise Floor
Noise Floor is the average level of the
visible code domain noise floor. This will
affect Rho. A high noise floor will result in
dropped calls, low signal quality, low data
rate, low sector capacity, and blocked calls.
Ec/Io
Ec/Io indicates the quality of the signal
from each PN. Low Ec/Io leads to low data
rate and low capacity.

Spectrum Master™ MS2720T Spectrum Analyzer Features
CDMA/EV-DO Measurements (Option 884)
EV-DO Measurements
The Spectrum Master features three
EV-DO measurement modes:
• RF Measurements
• Demodulation
• Over-the Air Measurements (OTA)
RF Measurements – Pilot and MAC Power
High values will create pilot pollution. High or low
values will cause dead spots/dropped calls and cell
loading imbalances/blocked calls.
Demodulation – Frequency Error
Calls will drop when mobiles travel at higher speed. In
some cases, cell phones cannot hand off into, or out of
the cell, creating island cells.
The goal of these measurements is
to increase data rate and capacity by
accurate power settings, ensuring low
out-of-channel emissions, and good signal
quality. These attributes help to create a
low dropped call rate, a low blocked call
rate, and a good customer experience.
Cell site technicians or RF engineers can
make measurements Over-the-Air (OTA)
to spot-check a transmitter’s coverage
and signal quality without taking the cell
site off-line. When the OTA test results are
ambiguous one can directly connect to the
base station to check the signal quality
and transmitter power.
Spectral Emission Mask (SEM)
SEM is a way to check out-of-channel
spurious emissions near the carrier. These
spurious emissions both indicate distortion
in the signal and can create interference
with carriers in the adjacent channels.
Faults leads to interference and thus, lower
data rates for adjacent carriers. Faults
also may lead to legal liability and low
in-channel signal quality.
Rho
Rho is a measure of modulation quality.
Rho Pilot, Rho Mac, and Rho Data are the
primary signal quality tests for EV-DO
base stations. Low Rho results in dropped
calls, low signal quality, low data rate, low
sector capacity, and blocked calls. This is
the single most important signal quality
measurement.
Over-the-Air Measurements – Multipath
Too much Multipath from the selected PN Code is the
primary issue of co-channel interference leading to
dropped calls and low data rates.
PN Codes
PN Code overlap is checked by the pilot
scanner. Too many strong pilots create
pilot pollution which results in low data
rate, low capacity, and excessive soft
handoffs.
Over-the-Air (OTA) Pilot Power
OTA Pilot Power indicates signal strength.
Low OTA Pilot Power causes dropped calls,
low data rate, and low capacity.

Spectrum Master™ MS2720T Spectrum Analyzer Features
WiMAX Fixed/Mobile Measurements (Option 885)
WiMAX Fixed/Mobile Measurements
The Spectrum Master features two
Fixed WiMAX and three Mobile WiMAX
measurement modes:
• RF Measurements
• Demodulation (up to 10 MHz)
• Over-the Air Measurements (OTA)
(Mobile only)
RF Measurement – Preamble Power
High or low values will create larger areas of cell-tocell interference and create lower data rates near cell
edges. Low values affect in-building coverage.
Demodulation – Frequency Error
Calls will drop when user’s equipment travels at high
speed. In severe cases, handoffs will not be possible at
any speed, creating island cells.
Over-the-Air Measurements – PCINR
A low Physical Carrier to Interference plus Noise Ratio
(PCINR) indicates poor signal quality, low data rate and
reduced sector capacity.
The goal of these measurements is
to increase data rate and capacity by
accurate power settings, ensuring low
out-of-channel emissions, and good signal
quality. These attributes help to create a
low dropped call rate, a low blocked call
rate, and a good customer experience.
Cell site technicians or RF engineers can
make measurements Over-the-Air (OTA)
to spot-check a transmitter’s coverage
and signal quality without taking the cell
site off-line. When the OTA test results are
ambiguous one can directly connect to the
base station to check the signal quality
and transmitter power.
Cell ID, Sector ID, and Preamble
(Mobile WiMAX)
Cell ID, Sector ID, and Preamble show
which cell, sector, and segment are being
measured OTA. The strongest signal is
selected automatically for the additional
PCINR and Base Station ID measurement.
Wrong values for cell, sector and segment
ID lead to dropped handoffs and island cells.
If the cause is excessive coverage, it also
will lead to large areas of low data rates.
Error Vector Magnitude (EVM)
Relative Constellation Error (RCE)
RCE and EVM measure the difference
between the actual and ideal signal. RCE
is measured in dB and EVM in percent.
A known modulation is required to make
these measurements. High RCE and
EVM causes low signal quality, low data
rate, and low sector capacity. This is
the single most important signal quality
measurement.
Preamble Mapping (Mobile WiMAX)
Preamble Scanner can be used with the
GPS to save scan results for later display
on a map. PCINR ratio can be used for the
strongest WiMAX preamble available at
that spot. The Base Station ID and Sector
ID information are also included so that
it’s easier to interpret the results. Once
PCINR data is mapped, it becomes much
easier to understand and troubleshoot any
interference or coverage issues.
Pass/Fail Test
Set up common test limits, or sets of limits, for
each instrument. Inconsistent settings between base
stations, leads to inconsistent network behavior.
