Abstract

A measuring device for over the air power measurements is provided. It comprises a power sensor unit, which is configured for measuring a power of a signal emitted by a device under test over the air and an indication unit which is configured for indicating the measured power optically. Moreover, the measuring device comprises a common housing, which encompasses the power sensor unit and the indication unit.

Claims

1. A measuring system comprising:

at least two measuring devices, each measuring device comprising;

a power sensor, configured for measuring a power of a signal emitted by a device under test over the air;

an indicator, configured for indicating the measured power optically; and

a common housing;

wherein the power sensor and the indicator are arranged in the common housing;

at least one camera, configured for recording images of the indicators of the at least two measuring devices, and

a central processor, configured for storing and/or processing the recorded images of the indicators of the at least two measuring devices.

2. The measuring system according to claim 1, comprising:

the central processor connected to the at least two measuring devices by a wireless or wired connection,

wherein the central processor is configured for communicating with the at least two measuring devices by the wireless or wired connection, and

wherein the at least two measuring devices are configured for transmitting the determined power values to the central processor by the wireless or wired connection.

3. The measuring system according to claim 2,

wherein the central processor is configured for determining the power values determined by the at least two measuring devices from the recorded images of the indication units of the at least two measuring devices.

4. The measuring system according to claim 3, wherein the central processor is configured for:

determining spatial positions of the at least two measuring devices from the recorded images of the indicators of the at least two measuring devices, and

storing the determined spatial position of each of the at least two measuring devices along with the power values determined by the central processor from the recorded images of the indicators of the at least two measuring devices.

5. A measuring method for over the air power measurement, comprising:

measuring a power of a signal emitted by a device under test over the air by a power sensor of a measuring device,

indicating the measured power optically by an indicator of the measuring device,

wherein the power sensor and the indicator are arranged in a common housing of the measuring device, and

wherein at least one camera records images of the indicators of the at least two measuring devices, and wherein a central processor stores and/or processes the recorded images of the indicators of the at least two measuring devices.
