RF components for test and measurement in anechoic chambers

The best solution is to put these 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, aviation components for radar and satellite communication, marine or space uplink applications although the mere size of an aircraft or ship with the installed solution may be a physical challenge.

It is also recommended to place little to none interfering RF measurement devices in the room itself to avoid any further effects. There is one drawback, you have to transmit the RF signals in and out the shielded RF chamber without having large losses. For this purpose, 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. The same statement applies to calibration kits and mechanical accessories such as gauges for checking mating face dimensions or torque wrenches for tightening coupling nuts. In all of these cases, SPINNER has established new, extremely high standards of precision which most users would not be without. Precise measured values are especially important when transmitting high power levels. SPINNER supplies coaxial measurement equipment of outstanding electrical and mechanical quality for use at frequencies from 1 kHz to 110 GHz.
