Spectrum Monitor OEM Board MS27100A

Spectrum Monitor Module

MS27100A
Overview

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
  • Integrated web server to view, control and conduct measurements via web browser
  • Watchdog timer to insure long-term stability for remotely deployed monitors
  • Low spur levels for accurate signal discovery
  • 20 MHz instantaneous FFT bandwidth

PC based VSA software for use with IQ data captured from an Anritsu Spectrum Analyzer enabled with Option 128

MX280005A Vector Signal Analysis PC software for Anritsu analyzers with option 128 is for testing physical layer modulation quality of various transmission standards. It serves a wide variety of markets, from aerospace to public safety (TETRA) to satellite communications and commercial electronics (ZigBee, Wi-Fi).

During the design and manufacturing stages of a wireless communication system, it is common to measure the modulation quality with benchtop instruments. Using the IQ capture (optional on some analyzers) together with the MX280005A software these measurements can be validated in a field environment. In framed mode, the software decodes common wireless signals including public safety (TETRA, P25, and DMR) to aerospace and satellite communications. In unframed mode, the software analyzes continuous modulation such as DQPSK, QAM, ASK, and FSK. The Field Master Pro MS2090A supports IQ captures up to 110 MHz bandwidth meaning narrow band communications signals or wideband satellite downlink signals can be captured and analyzed with the same application. Note that framed mode is not supported on the MS2710XA series of spectrum monitors.

MX280005A software can initiate the capture of IQ data over an Ethernet connection or a data capture can be triggered manually. Multiple analysis formats are provided including signal spectrum, EVM, constellation diagrams, eye diagrams, and numeric result tables. A comprehensive insight into all aspects of the transmitter performance is provided as multiple results windows can be displayed simultaneously.

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

Getting Started

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.
