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 ...

[Norman] put together a rather impressive 22,500 uF capacitor bank. In addition to find things to torture with the strong magnetic field generated by a sudden discharge, he’d like to measure the ...

When checking and verifying capacitors, inductors, diodes, bipolar transistors, and cables, the gamut of test methods can range from those used to confirm a defective component to identifying the ...

Power supplies use control-loop circuits to produce constant voltage or current. The transfer function—gain and phase as a function of frequency—provides valuable information about a control loop’s ...

The oscilloscope is probably the most versatile piece of test equipment you can have on your electronics bench, offering a multitude of possibilities for measuring timing, frequency and voltage as ...

Remember fundamentals and practice situational awareness in taking measurements. It’s not only using the right probe, but it’s also using the probe right. Eliminating measurement artifacts is tricky, ...

When developing oscilloscopes, test and measurement trends drive innovation and new designs, says Lee Morgan of Tektronix Time Domain. Talking to end-users of oscilloscopes has proved that the only ...
