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.
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.
