7880SA

Spectrum Analyzer

Product ManualManual
  • New

The 7880SA module is Evertz spectrum measurement and analysis module providing high-end performance at a low price. It is available as a 7800 series module as well as an integrated option to Evertz XPRF14-128x128 routing platform. When installed in a 7800 multi frame, It can function as independent spectrum analyzer in a satellite, cable or terrestrial network or as integrated monitoring device with Evertz RF transport and VLPro NMS solution.

7880SA uses state of the art digital technology and Fast Fourier Transformations to make lightning fast and accurate measurements. With a very low noise floor and large dynamic range, it is well-suited to measure any type of satellite, cable or terrestrial wireless carrier, including very small carriers, beacon signals and for carrier monitoring applications. 7880SA accepts all signals from 5MHz to 3GHz and input power levels ranging from -110 to +5dBm. RBW varies from 1Hz to 15MHz. The 7880SA can be connected to an external 10MHz reference for improved frequency accuracy and stability. All data communications with the 7880SA occurs via its built-in Ethernet port.

The 7880SA's powerful Graphical User Interface (GUI) is available using any standard web browser. No additional software is required. The GUI is very easy to use and operates like most traditional spectrum analyzers. It provides user selectable colors for markers and traces, allows storage of multiple traces and provides measurement reporting. The 7880SA GUI also includes a powerful built-in Carrier Monitoring function, which provides notification via email or SNMP of carrier measurements that exceed user-defined limits, offering you peace of mind that up to 100 of your carriers are operating as expected.

The 7880SA provides network access to all technical staff connected to the facility network or a corporate wide area network. This allows all technical staff the ability to monitor feeds and carriers at any time and from any location in the world using only a web browser.

For integration into a satellite terminal or measurement system, the 7880SA can be operated via its built-in GUI or the user can create a separate user interface using the publicly available API. An SNMP status interface is also provided.
