In this presentation, we will explain the advantages of the new wideband modulated load pull solution from Rohde & Schwarz, which addresses these limitations with a novel approach to RF frontend testing. By using the R&S®RTP oscilloscope instead of a traditional vector network analyzer (VNA), this solution enables wideband modulation characterization of RF frontends across varying impedances. This new test setup is ideal for verifying power amplifier performance when connected to an antenna, which typically shows a dispersive impedance.
