Rohde & Schwarz, IMST demonstrate solution for SATCOM terminal testing at EuMW 2023

Rohde & Schwarz has joined forces with IMST to demonstrate a solution for SATCOM (satellite communications) terminal testing at EuMW in Berlin. Testing the performance of satellite terminal systems and components with appropriate signals under realistic over-the-air conditions is crucial. SATCOM infrastructure size, form factor, weight and performance are all challenging for SATCOM terminal manufacturers.

At EuMW, Rohde & Schwarz and IMST will showcase a test solution that uses compact R&S ATS1800C CATR (compact antenna test range) based test chamber from Rohde & Schwarz for OTA measurements to characterise a SANTANA IV antenna array module from IMST. The R&S ATS1800C has a high-quality CATR reflector that creates a large quiet zone (QZ) for much higher measurement certainty relative to other solutions.

The R&S ZNA vector network analyser can complete test and securely characterise DUTs (device under tests). R&S AMS32 software measures technical parameters such as magnitude and phase of far field and near field distributions, as well as metrics such as error vector magnitude (EVM) to characterise the digitally-modulated transceiver performance.

The SANTANA IV module (FKZ 50RK1925) is a smart antenna terminal designed by IMST. It is equipped with electronically controlled antenna beam steering that allows the beam shape and pointing direction to be electronically adjusted without any moving mechanical parts.

The TX antenna array has 64 elements that support dual linear or circular polarisation. The array was designed for an operating frequency range from 29.5 GHz (gigahertz) to 30 GHz, which can be used for applications such as SATCOM-on-the-move (SOTM). The single 64-element module can be used as a base module for larger arrays.
