Today’s oscilloscopes have far more functionality than their old cathode-ray tube (CRT) analog counterparts. At first glance, the proliferation of all of those knobs and buttons may seem overwhelming, ...

Most engineering labs have digital oscilloscopes, but many engineers don’t fully explore their features. Among the more interesting features of a digital oscilloscope is its math channel, which can ...

These instruments are truly amazing today because they not only make all the basic measurements but also perform all sorts of other useful test, troubleshooting, and measuring functions thanks mainly ...

In the past, demonstrations of standing-wave phenomena could be done using an actual, physical transmission-line setup called “Lecher Lines.” 1 This method required laborious measurements to determine ...

Lots of readers are into toying around with RF and ham radios. One thing that is always of concern is tuning the antenna. New equipment is never cheap, so whenever another option comes along that uses ...

There was a time when every broadcast engineer had an oscilloscope for troubleshooting and aligning equipment, from a microphone input to the antenna. It is true that the nature of our plug-and-play ...
