To meet the extreme data throughput requirements of next-generation AI clusters, developers are exploring terahertz (THz) interconnects as a high-bandwidth, energy-efficient alternative to traditional copper and optical links. Characterizing these complex signals, which operate at frequencies up to 1 THz with high-order modulation, presents significant measurement challenges. Keysight software, particularly the Vector Signal Analysis (VSA) suite, is instrumental in this process. By providing advanced frequency estimation and streamlined equalization, the software allows engineers to accurately analyze high-speed waveforms. These capabilities empower researchers to optimize signal integrity, reduce design risks, and accelerate the commercial readiness of groundbreaking THz communication pla
