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 ...

Frequency Range Network analyzers measure an application’s fundamental frequencies, harmonics, or spurious signals on the high end, and baseband or intermediate frequency (IF) signals on the low end.

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 ...

It comes from Ted Yapo, it is indeed a tale of hardware heroics: what happens when you don’t want to spend sixty thousand dollars on a vector network analyzer? Ted’s talk begins with a need ...
