Measurement sites for radiated measurements and object characterization

Besides the standard labor measurement test spaces with mobile measurement equipment, we have two own "fix" measurement sites with dedicated RF-specifications. One of each is:

Open test range

Open test range. The device under test is mounted on a dielectric platform that can be elevated by the semi automated steering system.

Open test range. The receiving antenna is mounted on the dielectric mast. The antenna can be rotated along the polarization axis by steps of 5°.

The open test range has following core specifications:
  • Distance between the two dielectric masts: 15m
  • Maximal achievable height over terrain with both masts: 6m
  • Controlling of measurement height: Made by a laser measurement system attached to the DUT-platform
  • Typical reference antenna: WLE1058A, LogPer-Antenna 100MHz to 2.5GHz (3GHz typical)
  • Measurement control system: LabView
  • Measurement instruments: Selective receiver or vector network analyzer, dependent of the measurement task
  • Additional information: Some extensions of the measurement platform are in execution (state: October 2016)

Shielded anechoic chamber

The anechoic chamber is refurbished and first measurements are possible, but some details are still under work (@ Jan 2017). Initial measurements are already made, even though some further characterization work needs to be completed for the final release.

Anechoic Measurement Chamber. The surfaces and structure elements below the absorbers are with an excellent conductive surface coated, preventing external signals entering into the chamber.

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.
