Vector network analyzers (VNA) measure the complex transmission and reflection characteristics of two-port devices in the frequency domain. They sample the incident signal, separate the transmitted ...
At least that’s the lemonade [Josh Johnson] made from his lemon of a low-cost vector network analyzer. For the uninitiated, a VNA is a versatile test instrument for RF work that allows you to ...
Oscillators may use crystals as precise tuned circuits. If you have a vector network analyzer (VNA) — or even some basic test ...
