Figure 1 Use this third-order, 30-kHz filter circuit to observe a Class D amplifier’s output signal on an oscilloscope.

Among the more interesting features of a digital oscilloscope is its math channel, which can help you analyze hot-swap and load-switching circuits. Math functions can yield detailed information about ...

Ok, you want to get an oscilloscope. Where do you start? This TechXchange includes content that will be useful for the operation of a scope in your test environment. This includes considerations ...

And do you know whether they all work? I came across a neat video prepared by amateur radio operator W2AEW, a 10-minute tutorial on checking components. The video gives an example of performing simple ...

Now [jgpeiro] has made one which is light years ahead of the toy kits, using a Raspberry Pi Pico, a 100 MHz ADC, and an effort to design a better input circuit.

When work on an engine control circuit [Scott] found himself in need of a way to compare the performance of two control circuits at once. The hobby quality oscilloscope he owns wasn’t up to t… ...
