Anritsu Corporation reported that its Radio Communication Analyzer MT8821C, mainly for DUT maximum output power and receiver sensitivity testing, was recently opted by EDAG, a German engineering services and testing company.
Among the many advantages that the Anritsu MT8821C provides to EDAG Are:
- Quick and easy OTA (Over The Air) connection with a DUT,
- An intuitive graphical user interface (GUI) that is easy to use and train,
- Ability to quickly locate and configure important parameters for establishing an OTA connection, such as input/output levels and SIM card criteria.
Vehicle engineering, electronics, software and digitalization, and production (smart factories) are the main areas of focus for EDAG, a mobility and engineering development and testing firm.
With more than 50 years of technical experience, EDAG is renowned for their in-house 360-degree development methodology, which has established itself as a standard for excellence in the comprehensive creation of smart factories and automobiles.
The testing of communications technologies in the electronics and automotive sectors is a crucial component of EDAG. For instance, in addition to the typical OTA software updates, GPS for navigation, and Bluetooth connections, modern cars must take into account advanced communications like V2X (Vehicle-to-Everything), LTE, 5G, MIMO, and carrier aggregation.
Why EDAG Chose Anritsu MT8821C
The Anritsu MT8821C was chosen by EDAG due to its user-friendly measuring features in a single device and extensive test capabilities, which include support for NB-IoT and CatM1 technologies, LTE-Advanced, and software options including 3 CC carrier aggregation and 4×4 MIMO (individually tested).
While configuring some essential parameters for connecting, including input/output levels and SIM card parameters, is simple, the MT8821C’s graphical user interface is simple to use and train.
In order to eliminate user mistake in the creation of complex test conditions in RF testing, LTE has a feature called “Test Parameter Setup” that allows users to configure all pertinent parameters at once. The ability of the instrument to establish and sustain a connection with the DUT under dynamically changing pathloss settings, made possible by the broad dynamic range of its RF front-end interface, is a significant advantage when testing in OTA situations.
The MT8821C’s capability to be set up as an automated test system with a remote control via an Ethernet or GPIB interface is another crucial factor to take into account. In order to do the measurement in a fully automated manner without requiring user participation, users can also choose the necessary test case from a list using an automation tool called ATS that complies with the 3GPP RF test standard.
Leadership Comments
“We purchased MT8821C Anritsu radio communications analyzer with various hardware and software options. Key considerations were the instrument’s ease-of-use and ability to quickly establish an OTA connection with the DUT for maximum output power and receiver sensitivity testing as well as ability to keep and maintain the connection during the testing in radiated connection conditions. Another major factor for EDAG is that the MT8821C can be easily configured as an automated test system, even by novice users, reducing training time and increasing productivity.” says Andreas Bolaender, Dept. Manager EMC, EDAG.
Martin Varga, Anritsu’s Engineering & Technology Wireless Team Leader for the EMEA region added: “The purchase by EDAG validates the MT8821C as the ideal instrument for automated radio communications testing. Key to the success of the MT8821C is its built-in, flexible front-end with switches and RF dividers to eliminate the need for external combiners or a test set, thus simplifying test setup and calibration.”
