AI 中文摘要
本文评估了X波段同轴-波导过渡件附加长度法（又称端口延伸或信道偏移）的精度，并将其与是德科技（Keysight）和罗德与施瓦茨（Rohde & Schwarz）矢量网络分析仪（VNA）上的全波导校准进行比较。该研究探讨了成本与测量精度之间的权衡，强调在没有专用波导校准套件或过渡件完整S参数表征的情况下，使用这些数学校正技术的可行性。分析得出，使用同轴-波导过渡件时，附加长度法仅对传输测量能产生准确结果。
英文摘要
This paper assesses the accuracy of the "added length method" (also known as port extension or channel offset) for de-embedding coaxial-to-waveguide transitions in the X-band, comparing it to full waveguide calibration on both Keysight and Rohde & Schwarz VNAs. The study examines the trade-offs between cost and measurement accuracy, highlighting the feasibility of using these mathematical correction techniques in the absence of dedicated waveguide calibration kits or full S-parameter characterizations of the transitions. The analysis concluded that when using coaxial-to-waveguide transitions the added length method produces accurate results for transmission measurements only.
