Download Understanding the Fundamentals of Vector Network Analysis Application Note
Vector network analysis characterizes how RF components affect the magnitude and phase of swept-frequency and swept-power test signals. This application note connects transmission-line behavior and impedance matching to reflection, transmission, phase, group delay, and S-parameters, showing how incident, reflected, and transmitted waves relate to the measurements displayed on a vector network analyzer.
- Distinguish linear magnitude and phase changes from nonlinear signal behavior.
- Connect incident, reflected, and transmitted waves to reflection and transmission measurements.
- Use the Smith chart to relate complex impedance, reflection coefficient, and impedance matching.
- Interpret return loss, voltage standing wave ratio (VSWR), gain, insertion loss, insertion phase, and group delay.
- Map S11, S21, S12, and S22 to two-port reflection and transmission behavior.
