Anritsu MS27102A Remote Spectrum Monitor
The perfect tool for government regulators
Spectrum Monitoring
The MS27102A is part of a spectrum monitoring
system used to identify and measure spectrum
usage and to locate and remove illegal or
unlicensed interference signals. This is key in
keeping critical communication channels such as
transport, broadcasting, public safety and utilities
free of impediments and distortion. Regulating
the use of radio transmissions and mitigating
interference in the spectrum has become a high
priority with government regulators.
Spectrum Occupancy
Spectrum monitoring is also used to characterize
spectrum occupancy. Government regulators and
operators are often interested in determining the
usage rate for various frequency bands. Monitoring
these frequencies provides the information needed
to optimize spectrum for maximum utilization.
Spectrum can be re-purposed for other applications
or multiplexed with other signals using cognitive
radio techniques.
The MS27102A is rated to IP67 standards for outdoor deployment. It is dust tight (no
ingress of dust) as well as water resistant and comes with a mounting plate designed for
field applications.

Continuous. Fast. Reliable.
The MS27102A remote spectrum monitor is designed for outdoor environments where probes are
positioned in a permanent or semi-permanent location for radio surveillance and monitoring. Government
regulators often use outdoor monitors for enforcing spectrum policies. Capable of sweep rates up to 24
GHz/s, the MS27102A allows for the capture of many types of signals. This includes periodic or transient
transmissions as well as short “bursty” signals. The 20 MHz instantaneous FFT bandwidth available on the
MS27102A monitor provides the ability for wideband real-time captures of signal activity for subsequent
post-processing. IQ captures can be recorded both in block mode or streamed.

SpectraVision™ Application Software
For more detailed analysis of satellite signal quality,
SpectraVision software is available to demodulate signals
using the DVB-S1, DVB-S2 and IESS standards. Parameters
such as C/N, MER, EVM and modulation/coding schemes
are presented. Alarms can be triggered based on such
parameters as EVM or MER when values fall below a cer-
tain user-defined threshold.
Key Benefits of Remote Spectrum
Monitoring
• Automation and scalability
• Using Vision software or your own applications,
users can identify patterns of interference, record
a spectrum history and locate the sources of
problem signals
• SpectraVision software allows users to perform signal
analysis for satellite and other signal types
• New features and options can be added remotely,
no site visits required
Key Applications
• Network interference monitoring
• Geo-location of interference signals
• Maintain history of spectrum activity
• Set power threshold levels to automatically
generate alarms
Communicating with Remote Spectrum
Monitors
Integrated Web Server
Using an internet browser (Chrome and FireFox are
supported), a user from anywhere in the world can
log in to the spectrum monitor and control any of its
features. This includes such parameters as frequency
setting, RBW/VBW control, reference level configuration
and many other settings relevant to the user’s spectrum
monitoring application. At the same time, trace data,
spectrograms and other measurements can be viewed
inside the browser window.
SCPI Programming
Users can also write their own monitoring program
using available SCPI commands. Anritsu provides a user
manual listing each SCPI command, a description of the
commands and the correct syntax required for each
command. Additionally, each individual pair of IQ data
output by the monitors is time-stamped using high
precision GPS signals. This enables the use of IQ data for
Time Difference of Arrival (TDOA) applications for geo-
locating signal positions.
Vision™ Application Software
Vision works with the monitoring hardware to automate
the process of collecting measurement data, providing
useful information about network heath and use of the
spectrum. Two components of Vision, Vision Monitor and
Vision Locate, are responsible for monitoring and locating
interference signals. Vision Monitor automatically records
spectrum data, maintains a searchable spectrum history
database, enables alarm functions for unusual signal
activity, automatically sends email alerts and provides
a set of tools for managing the spectrum monitoring
system. Vision Locate provides the capability to geo-
locate interference or illegal/unlicensed signals.
