Overview

Anritsu MS27101A Remote Spectrum Monitor

Anritsu offers three models of remote spectrum monitoring products, designed to both mitigate interference problems and to identify illegal or unlicensed signal activity.  The MS27101A is housed in a ½ rack enclosure with 1U height, designed exclusively for indoor applications.   MS27102A is an IP67 rated device which operates outdoors, with the ability to be mounted on poles or walls (using the included mounting bracket).  The MS27103A is a multi-port spectrum monitor (12 RF In ports or optionally 24 RF In ports) which is ideal for cellular, DAS and other applications requiring the use of multiple antennas.

  • 9 kHz to 6 GHz
  • Sweep speed up to 24 GHz/s
  • Integrated web server to view, control and conduct measurements via web browser
  • Hardware watchdog timer to insure long-term stability for remotely deployed monitors
  • Low spur levels for accurate signal discovery
  • 20 MHz instantaneous FFT bandwidth
Applications

MS27101A Remote Spectrum Monitor Applications

  • Government regulators enforcing spectrum policies
  • White space monitoring
  • 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 communication channels open for trains
  • Cable TV, to mitigate leakage to outside environment and leakage into cable system

Getting Started

Connecting to the Remote Spectrum Monitor Using an Ethernet Network

Communication with the MS27101A is done via the GBit Ethernet port located on the instrument. Options are provided for using DHCP to obtain an IP address dynamically or for setting up a static IP address. The instrument is shipped with the default static IP address of 10.0.0.2. Once a connection is made to the instrument 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 on the Library tab.
