RayRobo is an automotive OTA test solution where an antenna is placed at the end of the movable robot and integrates with an EMC turntable to perform 3D wireless performance test; you can add the OTA test functions of RayRobo to an already existing EMC chamber. This option saves valuable construction time as well as cost. Refer to the product brochure for complete details.
Principle
Spherical near field sampling + NF-FF
Speed
Normal
Accuracy
Normal
Mechanical accuracy can match that of a large chamber, but it depends on the EMC chamber material
Measurable items
- Passive measurements
- ICV SISO
- ICV MIMO measurement (patented) option
- EMC test (patented) option
