Absolute Phase: The Role of Clear Phases and Calibration

Rohde & Schwarz, Thorsten Lück / Chiara Villante

This session focuses on the critical importance of phase information in RF measurements, often overlooked in favor of amplitude alone. We'll motivate the need for calibrated phases, overview calibration approaches with a detailed look at comb generators and their traceability and explore applications through case studies. These include time-domain transformations, frequency-converter validation, and instrument-specific considerations for VNAs.
