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 ...

Many common problems can be solved easily using the edge trigger of an oscilloscope. But sometimes a more complicated trigger mode such as pulse triggering can shorten the troubleshooting cycle. This ...

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 ...
