If you buy a serious scope these days, it is a good bet it will have at least two channels. There is a lot of value to being able to see two signals in relation to one another at one time. Even though ...

Equipped with a high-brightness CRT, the Model 6030C dual-trace analog oscilloscope from Protek comes with a pushbutton-activated component tester for checking inductors, capacitors, and diodes via a ...

I own two analog scopes: a B+K Precision 100 MHz dual trace portable that I bought back in the 1980s and a Tektronix analog storage tube mainframe scope with high-performance plug-ins acquired at an ...

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 ...

In circuit development and testing, it's often necessary to display more channels than today's oscilloscopes provide. One simple solution is to trigger several oscilloscopes in parallel. However, a ...
