RF Components for Test and Measurement in Anechoic Chambers for Mobile Communication
Radio frequency testing of mobile communication and professional mobile radio equipment in the open-air environment is influenced by a large number of disturbing and unwanted signals in the atmosphere such as radar, broadcast and many other radio frequency emissions. This effect can cause misleading test results.
The best solution is to put these mobile communication devices in isolated rooms, shielded boxes or special RF test chambers with low-reflection surfaces, so-called anechoic chambers. Anechoic chambers are common for test scenarios of antennas and components for mobile communication and PMR/TETRA.
It is also recommended to place little to none interfering RF measurement devices in the room itself to avoid any further effects. However you have to transmit the RF signals in and out the shielded RF chamber without having large losses. For mobile communication SPINNER offers an entire portfolio of highly suitable, up-to-date measurement equipment to achieve the best signal transmission between the measurement device and the components under test (DUT) in an RF diagnostic chamber.
Particularly with vector network analyzers (VNA), it is essential to use high-precision connectors, terminations and adapters for PMR and mobile communication. The same statement applies to calibration kits and mechanical accessories. SPINNER has established new, extremely high standards of precision for the mobile communication testing equipment.
