Multi-Channel Antenna Calibration, Reference Solution - 1

SOLUTION BROCHURE Multi-Channel Antenna Calibration, Reference Solution Challenge the Boundaries of Test Agilent Modular Products Accelerate the calibration of large antenna arrays with precise cross-element phase and magnitude measurements. Get ready for the future with increased measurement bandwidth and system flexibility. Multi-channel antenna calibration challenges As the market for multi-channel, phased-array antennas grow, manufacturers experience increased pressure to reduce cost and increase test capacity. At the same time, manufacturers would like to expand test system flexibility to cover broad use cases and provide options for future upgrades. The calibration and testing of multi-channel antennas brings many challenges and, therefore requires a new testing approach: • An increase in the number of array elements results in an increase in test times and test complexity • For precise beam-forming, it is critical to achieve phase coherent sampling across all input channels, providing relative amplitude and phase measurements • Advancements in antenna and radar technologies requires a test system that is flexible and upgradeable Multi-channel antenna calibration, Reference Solution The multi-channel antenna test Reference Solution is a combination of hardware, software, and measurement expertise providing the essential components of a narrow-band antenna calibration test system. This enables engineers to use, enhance, or modify the test system as required to meet specific test application needs including scalable channel count, options for downconversion of antenna receive channels, selectable analysis BW, and choice of RF/micro wave sources and LO. It can also be extended to wide-band measurements as needs change. To facilitate evaluation and integration in your test environment, you can use supplied test code examples to set up receiver channels, including DDC, make phase and magnitude measurements, add channel-channel correction factors, and export measurements for post-processing.

Multi-Channel Antenna Calibration, Reference Solution - 4

Antenna calibration example software The Reference Solution is provided with a C# test code exam- ple specifically designed to collect data from an antenna under test and compute cross-channel magnitude and phase data. To accelerate test development and facilitate the integration in your test environment, the source code for the example soft- ware is provided in the form of a .NET class library. This allows you to build-upon the example (using Microsoft Visual studio or National Instruments LabVIEW) and customize the collection and processing of data to your specific application needs. Test...

Multi-Channel Antenna Calibration, Reference Solution - 5

Wide-band signal analysis software Integrating the Reference Solution into your test environment When integrating this Reference Solution into your test environment, keep the following notes in mind: Using the M9703A and DDC with Agilent 89600 VSA software for advanced measurement analysis enables cross-channel baseband measurements including phase and amplitude. The VSA software provides seamless control of the M9703A digitizer including DDC and multi-channel support (up to 8-channels). It is particularly useful when more complete visualization is required with wide-band measurements. •...
