Demonstration of the MT8820C Radio Communications Analyzer
At CEATEC Japan 2010, Anritsu exhibited the MT8820C radio communications analyzer used for testing the wireless functionality of LTE devices, and presented a display in which the connectivity of LTE (3.9G) mobile phones was demonstrated.
Real-time monitoring of communications status
The MT8820C radio communications analyzer exhibited by Anritsu tests the wireless functionality of 2G, 3G, and next-generation LTE mobile phones. This product incorporates base station functionality and can emulate the exchange of signals between the device and base stations to enable monitoring of signal switching status and other communications. In addition, passing communications between tested mobile phones and the MT8820C through a fading emulator (artificially creates variations in radio waves resulting from movement), allows monitoring of signals from devices moving at different speeds, such as while the user is walking or driving. The booth also exhibited a device called a signal analyzer, which does not have base station emulation functionality and only monitors wireless signals.
Practical for manufacturing and testing processes
As for the device tested, the demonstration used a type of LTE mobile terminal actually marketed in North America, which was carried out by connecting it to the MT8820C that gave off radio waves only in a specific space. Transmission and reception status of radio waves in both directions were displayed as numerical values and graphs to simplify the monitoring of wireless transmission status. Anritsu stated that in addition to testing on production lines for mobile devices, this technology can also be used for inspection testing by mobile phone companies, as well as in problem analysis when repairing or identifying defects.
