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:
•t An increase in the number of array elements results in an
increase in test times and test complexity
•t For precise beam-forming, it is critical to achieve phase
coherent sampling across all input channels, providing relative amplitude and phase measurements
•t 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.
