First claim
Opening claim text (preview).
What claimed is: 1. A measuring system for performing over the air power measurements, comprising: a detector module, comprising a detector input, a transmitter module, comprising a transmitter output, and an antenna, wherein the detector input and the transmitter output are within a single housing and are at least temporarily connected, wherein at least the transmitter output or the detector input are at least temporarily connected to the antenna, wherein the detector module comprises detector diodes adapted to rectify a signal received by the antenna, wherein the transmitter module comprises a signal source, wherein the signal source is adapted to be regulated in a digital manner, wherein the detector input and the transmitter output are connected by an electrical power coupler, wherein the antenna is connected to a direct path of the power coupler, and wherein the power coupler comprises a first coupling path and a second coupling path and whereby the first coupling path and the second coupling path are connected to the detector module. 2. The measuring system of claim 1 , wherein the detector input and the transmitter output are connected in a switchable manner. 3. The measuring system of claim 1 , wherein the detector input and the transmitter output are connected interchangeably switchable to the antenna. 4. The measuring system of claim 1 , wherein the detector input and the transmitter output are connected by a power coupler, and wherein the power coupler is adapted to couple out: a first signal, proportional to a signal received by the antenna, and/or a second signal, proportional to a signal transmitted by the transmitter module. 5. The measuring system of claim 1 , wherein the detector input and the transmitter output are connected by a power coupler, wherein the power coupler is adapted to: couple out a first signal proportional to a signal transmitted by the transmitter module, and couple in a second signal transmitted by the transmitter module. 6. The measuring system of claim 1 , wherein the signal source is a voltage controlled oscillator, or a fixed frequency oscillator, or a synthesizer. 7. The measuring system of claim 1 , wherein the signal source is adapted to be regulated in an analog manner. 8. The measuring system of claim 1 , wherein the transmitter module comprises an amplifier or a damper. 9. The measuring system of claim 1 , wherein the transmitter module comprises an input, which is connected to an external signal source. 10. The measuring system of claim 1 , wherein the transmitter module comprises a mixer. 11. The measuring system of claim 10 , wherein the mixer comprises an input, which is connected to an external signal source.
