Abstract

A measuring system for performing over-the-air measurements on a device under test is provided. The measuring system comprises an antenna, configured for performing over-the-air measurements, an alignment device and an antenna holder interface, configured for interchangeably holding one of the antenna and the alignment device. The alignment device is configured for aligning the antenna holder interface and the device under test.

First claim

What is claimed is:

1. A measuring system for performing over the air measurements on a device under test, comprising:
an antenna, configured for performing the over the air measurements,
an alignment device, and
an antenna holder interface, configured for interchangeably holding one of the antenna or the alignment device,

wherein the alignment device is configured for aligning the antenna holder interface and the device under test.

2. The measuring system of claim 1 ,
wherein the alignment device is a laser, configured for emitting a laser beam.

3. The measuring system of claim 2 ,
wherein the antenna holder interface is configured so that a main radiation direction of the antenna is fixed to a first direction relative to the antenna holder interface, when the antenna holder interface holds the antenna, and
wherein the antenna holder interface is configured to hold the alignment device so that the laser beam is emitted into said first direction.

4. The measuring system of claim 3 ,
wherein the antenna comprises an interface configured to connect to the antenna holder interface, and/or
wherein the alignment device comprises an interface configured to connect to the antenna holder interface.

5. The measuring system of claim 3 ,
wherein the antenna holder interface is aligned with the device under test, when the first direction points to a specific point of the device under test.

6. The measuring system of claim 5 ,
wherein the system comprises the device under test,
wherein the device under test comprises an interface, configured for holding the alignment device.

7. The measuring system of claim 6 ,
wherein the interface of the device under test is configured for holding the alignment device, so that the alignment device emits the laser beam into a second direction fixed with regard to the device under test, when the alignment device is held by the interface of the device under test.

8. The measuring system of claim 7 ,
wherein the device under test is aligned with the antenna holder interface, when the second direction points to a specific point of the antenna holder interface.

9. A method for performing measurements on a device under test, comprising:
connecting an alignment device to an antenna holder interface,
aligning said alignment device with the device under test,
connecting an antenna to the antenna holder interface while keeping the orientation and position of the antenna holder interface fixed, and
performing measurements on the device under test, using the antenna.

10. The method of claim 9 ,
wherein the alignment device emits a laser beam.

11. The method of claim 10 ,
wherein a main radiation direction of the antenna is fixed to a first direction relative to the antenna holder interface, when the antenna holder interface holds the antenna, and
wherein the antenna holder interface holds the alignment device so that the laser beam is emitted into said first direction.

12. The method of claim 11 ,
wherein the antenna holder interface is aligned with the device under test, when the first direction points to a specific point of the device under test.

13. The method of claim 12 ,
wherein an interface of the device under test can hold the alignment device so that the alignment device emits the laser beam into a second direction fixed with regard to the device under test, when the alignment device is held by the interface of the device under test.

14. The method of claim 13 ,
wherein the device under test is aligned with the antenna holder interface, when the second direction points to a specific point of the antenna holder interface.
