Testing RF devices, like power amplifiers, requires a certain input power at the device under test (DUT). Sometimes, more power than a signal generator can deliver is needed. This may be the case when devices require higher input power, or when they need to be connected using long cables, which introduce large insertion losses at high frequencies. In these cases, an external amplifier can be used to deliver the required power to a DUT.This application note gives a guideline how to increase the power delivered to a DUT by an R&S®SMW200A vector signal generator using an external amplifier.It covers shifting the power reference plane from the generator output to the DUT input using an R&S®NRP power sensor and mitigating linear and nonlinear distortions using an R&S®FSW signal and spectrum analyzer.

With the rise of Low Earth Orbit (LEO) and Medium Earth Orbit (MEO) satellite constellations for broadband data connectivity over the last few years, the need to dynamically simulate the channel between the satellite and user equipment (UE) or the satellite and the ground station (GS) has grown at a staggering pace. The satellite channel is subject to various atmospheric effects and the relative motion between the satellite and UE, resulting in frequency and level variations that depend on the satellite's position in the sky. Consequently, it is essential for manufacturers of related receivers and other hardware components to consider these effects during the design and production phases to ensure optimal performance and reliability.In this application note, the focus will be on giving an overview of the functionalities of the R&S Space Nexus and explaining how to use the software to create realistic fading files out of a given Two Line Elements (TLE) file that is describing the trajectory of a satellite.
