AT1000L Automotive OTA measurement sub-system for SISO/MIMO antennas, passive and active test (TRP/TIS/EIS/EIRP) for reliable automotive connectivity.
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. | Passive and active tests (TRP, TIS, EIS, EIRP) |
| Differentiated Asymptotic Near Field (ANF) method testing software | Enabling fast EIRP/EIS SISO testing |
| No requirements for large chamber | Radiated-Two-Stage (RTS) method for MIMO testing software |
