QUESTION: If PDN (Power Distribution Network) analysis is an assessment of the input power supply voltage to a CPU then why is it measured using a VNA and not an oscilloscope? ANSWER: First, your ...

The test and measurement world is almost universally a 50Ω environment. It used to be that, if you wanted to characterize a 75Ω cable for use in a 75Ω environment, you had to buy a very expensive 75Ω ...

As the use of microcontrollers, CPUs and FPGAs continues to grow, more engineers are facing challenges with their power distribution network (PDN) design. Many engineers are just starting to perform ...

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 ...

If you’ve done any amount of electronic design work, you’ll be familiar with the need for decoupling capacitors. Sometimes a chip’s datasheet will tell you exactly what kind of caps to place where, ...
