Abstract
A method includes defining a Center-of-Radiation Reference for a device under test, the CORR indicating a reference origin of an electromagnetic wave pattern formable with the DUT; determining a 3-dimensional orientation information with respect to the CORR, the 3-dimensional orientation information indicating a direction of the electromagnetic wave pattern; and providing the CORR and the 3-dimensional orientation information to a measurement system.
Claims33
A method comprising:
- defining a Center-of-Radiation Reference for a device under test, the CORR indicating a reference origin of an electromagnetic wave pattern formable with the DUT;
- determining a 3-dimensional orientation information with respect to the CORR, the 3-dimensional orientation information indicating a direction of the electromagnetic wave pattern;
- and
- providing the CORR and the 3-dimensional orientation information to a measurement system.
A method comprising:
- detecting a radio frequency electromagnetic wave pattern from a DUT;
- receiving information indicating a Center-of-Radiation Reference for a device under test, the CORR indicating a reference origin of an electromagnetic wave pattern formed with the DUT and receiving a 3-dimensional orientation information with respect to the CORR, the 3-dimensional orientation information indicating a direction of the electromagnetic wave pattern;
- and
- evaluating the detected radio frequency electromagnetic wave pattern with respect to a match with the CORR and the 3-dimensional orientation information.
An apparatus comprising:
- a display;
- and
- an interface configured to receive a signal indicating a request that the apparatus is requested to perform a test mode;
- wherein the apparatus is configured to switch to the test mode responsive to the signal and to display a predefined optical signal pattern with the display, the optical signal pattern providing at least a part of a set of reference markers at the apparatus.
A non-transitory digital storage medium having a computer program stored thereon to perform the method comprising:
- defining a Center-of-Radiation Reference for a device under test, the CORR indicating a reference origin of an electromagnetic wave pattern formable with the DUT;
- determining a 3-dimensional orientation information with respect to the CORR, the 3-dimensional orientation information indicating a direction of the electromagnetic wave pattern;
- and
- providing the CORR and the 3-dimensional orientation information to a measurement system,
- when said computer program is run by a computer.
A non-transitory digital storage medium having a computer program stored thereon to perform the method comprising:
