VNA basics
A Vector Network Analyzer (VNA) measures the reflection and transmission behavior of a device under test
(DUT) across a configured frequency range.
The NanoVNA V2 is a two port T/R (transmission/reflection) VNA which can measure the S parameters S11 and
S21 of a two port network, or the reflection coefficient (S11) of a one port network.
Before any measurements are performed, the VNA must be calibrated. See section 3.1.Calibration for details.
