As wireless communications, such as 4G LTE, Wi-Fi, and Bluetooth®, become increasingly integrated into our lives, the demands of their test bench increases
too. In this article, we will discuss what a wireless communication tester is and how ADI's products fit in its signal chain.
System Design Considerations
Ease of Configuration, Operation, Maintenance, and Upgrade
Factors such as easy configuration, operation, maintenance, and upgrading are important for all testers. However the DUT and the parameters to test vary. To
deal with such a challenge, a common approach is to use a similar graphic user interface (GUI) for different hardware platforms in different testers. Moreover,
if the same hardware platform can be used to cover all test requirements, it would be the best solution.
Excellent Performance and Rich Functionality
Beyond basic design and trouble shooting, the testers may be operated in complex interference, fading, and handoff scenarios and explore every nuance of a
standard. So excellent performance and rich functionality are also critical.
Solutions from ADI
A wireless communication test bench includes source (stimulus to the DUT) and measurement (response from the DUT). Below is an example implemented by
ADI's RF Agile Transceiver ™, AD9361, which can cover all LTE channel bandwidths with integrated power solution, ADP505x, and RF/IF gain block, ADL5601/
ADL5602.The completed solution consists of source units and measurement units system block diagram
