Spectrum Monitor Module MS27100A

Overview

Description
Features

The MS27100A facilitates the identification and removal of illegal or unlicensed interference signals. By monitoring spectrum on a continual basis, problem signals can be identified as they occur in real time. Patterns of unwanted signal activity can also be examined, providing an efficient way to characterize and locate the source of the interference problem.

In addition to interference detection, the MS27100A 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.

Spectrum monitoring can also serve to enforce compliance with government regulations. Police, fire fighters, air traffic control, military and emergency services must all have access to communications free of impediments and distortion. Compliance with spectrum regulations is often enforced by spectrum monitoring.

With its small form factor, the MS27100A is ideally suited for placement in racks where space is at a premium. The MS27100A also supports an IF output (140 MHz) which can be used for further processing by the user.

9 kHz to 6 GHz
Sweep speed up to 24 GHz/s

Applications

Detection of illegal or unlicensed AM/FM/Cellular broadcasts
Sensitive site monitoring (national borders, military facilities, nuclear power plants…)
Airport monitoring (with communication frequencies often adjacent to FM bands)
Monitor jails/prisons for illegal broadcasts
Positive Train Control (PTC), insure clear communication channels for trains
Cable TV, to mitigate leakage to outside environment and leakage into cable system
Government regulators enforcing spectrum policies

Connecting to the Remote Spectrum Monitor using a Ethernet Network

Communication with the MS27100A is done via the GBit Ethernet port located on the board. Options are provided for using DHCP to obtain an IP address dynamically or for setting up a static IP address. The board is shipped with the default static IP address of 10.0.0.2. Once a connection is made to the board via a laptop/PC, the IP type can be changed via the user interface presented by the monitor’s integrated web server.

For DHCP usage, Anritsu offers an Ethernet Discovery Program which queries your network for all connected devices. The Ethernet Discovery Program can be found on the Anritsu website.

Some customers may prefer to use a Domain Name Server (DNS) where the spectrum monitor’s hostname can be resolved into its dynamic IP address. A DNS server provides the ability to create a hostname. Examples might include hostnames such as “mymonitor1.org” or “spectrum1.net”. There are several free DNS services available. One such service used by Anritsu is www.no-ip.com. You will need to create an account and select a hostname for your instrument.

Further details about configuring your Ethernet connection can be found in our Configuration Quick Start Guide available for download in the Library tab.
