Optimize Full Vehicle OTA Testing for Reliable Connectivity
The Full Vehicle OTA Testing solution combines RF instrumentation and advanced OTA (over-the-air) antenna measurement software, integrated in an automotive-grade anechoic chamber, to improve efficiency in full vehicle antenna testing. It supports passive and active measurements such as TRP, TIS, EIRP, and EIS for both SISO and MIMO antennas. It helps reduce test time, complexity, and the required chamber size.
Advanced OTA Methodologies
Leverage differentiated ANF and RTS methods to improve OTA measurement efficiency across full‑vehicle validation workflows.
Repeatable Results
Patented AUT offset compensation reduces sensitivity to antenna positioning offsets for more consistent, repeatable outcomes.
SISO and MIMO Coverage
Measure and validate performance across single‑input, single‑output (SISO) and multiple‑input, multiple‑output (MIMO) antenna configurations.
Higher Throughput, Lower Cost
Keysight’s Automotive Over-the-Air (OTA) Measurement Sub-System combines test equipment and innovative software to boost test efficiency while reducing costs.

Innovative Automotive Over-the-Air Methodologies Improving Testing Efficiency
In the evolving automotive connectivity landscape, vehicles use various antennas to support functions like entertainment, navigation, safety, autonomous driving, and intelligent transportation. Testing full vehicle antenna is complex and costly due to the need for enormous size chambers. High sampling rates remove the eccentricity issue while decreasing the test efficiency. In this comes challenges of cost, complexity, and time-to-market.
Addressing these challenges, Keysight’s Automotive Over-the-Air (OTA) Measurement Sub-System offers measurement instruments and innovative software to reduce testing complexity and time. For both passive and active tests, Single Input, Single Output (SISO), and Multiple Input Multiple Output (MIMO) testing. The sub-system provides comprehensive testing capabilities for vehicle antennas, ensuring reliable performance and connectivity. Leverage innovative software methods to boost test efficiency and reduce costs.

Frequently Asked Questions
Full-vehicle OTA testing measures an antenna’s wireless performance with all antennas and modules integrated into the final vehicle environment. It validates real-world effects like antenna radiation patterns, sensitivity, and total radiated performance, including interference and co-existence issues that can be introduced by the vehicle structure, materials, and onboard electronics. This takes place in a fully shielded (anechoic) chamber that eliminates external interference signals, ensuring accurate, reproducible results.
The number of wirelessly connected devices integrated into vehicles is increasing, and with it the system’s complexity. Crosstalk and interference negatively impact their operation, and ultimately, the quality-of-service experienced by the user. Testing the integrated system before vehicle roll out helps mitigate those physical layer challenges on time.
With increasing operating frequencies, the antenna far field increases. As antennas are installed in various spots on or within the vehicle’s metallic hull, their far field, and therefore, the antenna radiation pattern, changes. Additionally, multiple antenna’s co-existence within the same vehicle must be tested in a realistic setup.
Large antenna far fields require extremely large anechoic chambers. Near field to far field NF2FF transformation algorithms are time consuming. High sampling rates remove the antenna placement eccentricity while decreasing test efficiency. This results in increased cost, complexity, and time-to-market.
