S11 · basics
Introduction to vector measurements
Learn what a NanoVNA actually measures, how to calibrate it and how resistors, capacitors and inductors appear in S11 and on the Smith chart.

NanoVNA course: four modules, one measurement strategy
From your first reliable S11 measurement to investigating antennas, filters, cables and unknown RF networks independently.
NanoVNA course
From a graph to a well-founded conclusion
A NanoVNA is much more than an SWR meter. It measures both magnitude and phase, allowing you to investigate how components, antennas, cables and filters behave across a frequency range.
The four practical modules build on each other. First learn to measure reliably, then explain what you see, and finally choose the right measurement independently.

S11 · further exploration
Understanding impedance and resonance
Use the NanoVNA to investigate how R, L and C combine to form impedance and how series and parallel resonance appear in S11 and on the Smith chart.

S21 · transmission
Measuring transmission, filters and cables
Learn to interpret S21 and dB, recognise four filter types and discover how electrical length and quarter-wave behaviour affect coax measurements.

Practical application
Investigating RF problems independently
Apply S11, S21, impedance and the Smith chart independently to antennas, matching, coax, unknown networks and common-mode chokes.
