Typical reference antenna2: QRH18, Quadridged-Antenna 1 GHz to 18 GHz
Measurement control system: LabView
Measurement instruments: Selective receiver or vector network analyzer, dependent of the measurement task
The extensions of the measurement platform are finished
3D-Antenna pattern measured in one shot
The axis extension of the positioner allows to measure the DUT in one shot over the whole surface of the sphere. It does not
matter if the DUT itself emits the signal or if the measurement signal is generated with the VNA and applied to the DUT.
Measured, normalized Antenna Gain. The DUT is sweept over the requested angular Theta and
Phi ranges while the co- and cross polar signal portions are recorded. Out of them are the single polarization elements
calculated for display in the graphs.
3D Antenna Pattern. The recording of the data is made in one setup. The co- and the cross
polar portions are recorded, out of them are the single polarizations calculated and displayed.
Shielded anechoic chamber
The anechoic chamber upgrade is finished. The covered frequency range starts at 500 MHz and ranges up to 40 GHz. The upper
frequency limit is mainly driven by the test instruments and is not limited by the absorbing elements.
Anechoic measurement chamber . All surfaces are completely covered by absorbing elements, making sure that incident waves are absorbed
by 30dB and more. This leads to the fact that the reflected energy has a very, very low level.
Advantages of the two measurement sites
Through the availability of the two measurement sites are we very flexible to measure your emitting unit under tests or to characterize your antennas. Dependent of the measurement
job are we using VNA's or selective receivers to operate the site. This allows high flexibility to make customized measurement setups. The devices under test and the used measurement
equipment are controlled by LabView, allowing higher efficiency and excellent reproducibility. By doing so, the measurement processes are standardized and automated.
