: Standard calibrations like Thru-Reflect-Line (TRL) and Line-Reflect-Line (LRL) are critical for high-accuracy measurements, especially in waveguide or on-wafer setups where fixed standards can be manufactured to tighter tolerances than sliding terminations.

While measuring S-parameters (reflection and transmission) remains the core of network analysis, modern Vector Network Analyzers (VNAs) have evolved into "nonlinear" instruments. Modern RF and Microwave Measurement Techniques

In modern highly integrated chipsets, the antenna is often built directly into the package (Antenna-in-Package or AiP), making traditional cabled testing impossible. making traditional cabled testing impossible.
