Deterministic detection and vector band stitching for the measurement of 6G wideband test signals

This paper proposes a testbed for 6G component testing under ultra-wideband modulation using a Vector Network Analyzer. The vector spectrum is acquired by chunks and stitched back together. Deterministic image rejection and phase stitching methods to acquire wideband vector data are detailed. The state-of-the-art floor EVM of the proposed testbed is measured with multi-GHz wide test signals.
