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 ...

Newman-Kees Principal Consulting Engineer Frank Hertel says a friend recently brought him an old LPB 30-Watt AM transmitter for repair. It’s a good low-power transmitter, but this one had been abused.

When you perform EMC tests, you often think of emissions measurements made with a spectrum analyzer. But, there are EMC applications for oscilloscopes. A relatively underutilized use for oscilloscopes ...

What can we say, we’re a sucker for projects featuring our logo. That being said, this one is seriously awesome. [CNLohr] has figured out how to create a vector display output on an oscilloscope… from ...

For some applications such as extremely low-noise amplifiers or precision automated test equipment, it’s still possible to find a linear power supply at work converting AC utility power into some form ...

Engineering consultant Frank Hertel outlines a method of measuring an inductor’s value using only an oscilloscope and a signal or function generator.

What if a variable-frequency drive (VFD) on a critical system has a fault indication, the “error” LED on a DC power supply has turned on, or a conveyor belt has started behaving erratically — most ...
