Time-domain reflectometry (TDR) is a technique that measures and displays the impedance of a network (cable, filter, and so on) over time. Traditionally, this is done with a device that generates very ...

The Vector Network Analyzer (VNA) has come a long way since it was used to test antenna arrays for military applications. Vector Network Analysis can be used to perform more than 100 critical ...

If you are making certain precision measurements, you know you need to terminate the connections with the right impedance, normally 50 ohms. Proper termination minimizes reflections on the line which ...

What are your favorite hardware tools that you use? My favorite hardware tool is the anechoic antenna measurement chamber. I also enjoy using vector network analyzers (VNA). Every electrical engineer ...
