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 ...

You're probably familiar with clamp on current probes, but chances are you don’t know much about the Rogowski current probe. A Rogowski coil produces a voltage that is proportional to the rate of ...

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 ...

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, ...
