Datasheet

Overview

The Anritsu MS27103A is a remote spectrum monitor for identifying and locating interfering signals. Typical uses are cellular base station (BTS) receive monitoring, distributed antenna systems (DAS) and satellite earth stations. Interference can come from illegal transmitters or from unintended sources such as intermodulation products, and it reduces network data capacity.

The instrument sits in a rack-mountable enclosure with 12 RF inputs as standard, or 24 with Option 424. A high-speed electronic switch moves between ports in approximately 300 ns, and the datasheet specifies more than 30 dB isolation between RF input ports. The standard configuration suits three-sector BTS architectures with multiple carriers per sector. The 24-port version suits six-sector sites or other applications that need many antennas and frequency bands.

The MS27103A sweeps at up to 24 GHz/s, so it can capture periodic, transient and short bursty signals. A 20 MHz instantaneous FFT bandwidth allows wideband real-time captures for later post-processing. IQ data can be recorded in block mode or streamed. A save-on-event function records spectrum measurements only when user-set thresholds are exceeded.

Remote operation and communication

An integrated web server lets users control the monitor and view traces and spectrograms from Chrome or Firefox on any device. Communication runs over Gigabit Ethernet using DHCP, a static IP address (default 10.0.0.2) or DNS. Users can also write their own control programs with SCPI commands. IQ samples are time-stamped by the built-in GPS receiver, which supports time difference of arrival (TDOA) geolocation. For remote deployments, the monitor provides a watchdog timer, remote firmware updates and a protected "Golden" firmware image for automatic recovery.

Software

Vision software (options 400 and 401) runs on a Windows PC. Vision Monitor records spectrum data, keeps a searchable spectrum history database, raises alarms and sends email alerts. Vision Locate geolocates interference or unlicensed signals using three or more monitors. With Option 128, IQ Signal Master MX280005A software can post-process captured IQ data.
