WMK: Unlocking the Power of Phase Information in RF Measurements

Presentation Abstract
In RF device characterization, understanding and utilizing phase information is crucial for achieving accurate measurements. This workshop is designed for engineers, technicians, and researchers who seek to deepen their knowledge of phase references and their applications in vector network analyzers (VNAs) and vector signal analyzers/generators (VSAs/VSGs). The primary goal of this workshop is to emphasize the significance of phase information in RF measurements. We introduce the concept of a “signal comb” as a phase reference and a tool for enhancing measurement accuracy. Participants will gain insights into how a comb generator works and how phase references can improve the reliability of amplitude and phase measurements across various RF applications. Key Topic #1 — Understanding Phase Information: • Introduction to phase information and its relevance in RF measurements; • Discussion of the limitations of traditional amplitude measurements and the often-overlooked phase references. Key Topic #2 — The Role of Signal Comb: • Explanation of what a signal comb is and its function in RF testing; • How a signal comb acts as a “Swiss army knife” for calibration and broadband verification; • Design overview of a comb generator and its traceability. Key Topic #3 — Benefits of Phase References: • Detailed exploration of how aligning VNAs and VSAs/VSGs to a known phase reference enhances measurement accuracy; • The importance of traceable calibration for establishing transfer standards in amplitude and phase uncertainties. Key Topic #4 — Practical Applications: • Hands-on examples demonstrating the application of phase calibration in real-world scenarios; • Case studies including time domain transformation and frequency-converting circuit measurements. Key Topic #5 — Advanced Measurement Techniques: • Techniques for aligning multi-port VSAs in amplitude, phase, and time using phase references; • Over-the-air measurement of group delay in low-noise block downconverters (LNBs) and pulse response determination of amplifiers at optimized operating points. Who Should Attend — This workshop is ideal for RF engineers, measurement technicians, and researchers involved in RF device characterization and testing. Whether you are a seasoned professional or new to the field, this workshop will provide valuable insights and practical skills to enhance your measurement capabilities.
