Sometimes the test signal needs a flaw. A clean waveform is easy to generate, but a narrow glitch in the middle of it can replicate a behavior or gives an oscilloscope something …

I dive into Pico Technology’s latest PicoScope oscilloscope software, PicoScope 7. Using a PicoScope 2000A (from the element14 Community), James walks through key measurements and …

A long time ago, I made a video suggesting math was unnecessary to determine proper pull-up resistor values. Like most generalized statements, that suggestion is not always true. …

A powerful, but an underused feature of digital oscilloscopes is the trigger circuit. Learn from James how to use an oscilloscope’s trigger to find glitches, measure pulse widths, …

When running on a battery, it is important to know what parts of your circuit draw the most current. Profiling is a process where you look at sections of code or interactions with …

When connecting multiple oscilloscope probes to a circuit, does each probe need to connect to ground? The short answer is yes! Why? The long answer is kind because of the ground …

Every digital oscilloscope I have ever used has a menu or dialog for “acquisition modes.” And depending on the current settings, changing that acquisition mode does not seem to …

Measuring a switch-mode power supply (SMPS) with a DMM might show a stable voltage. But the same DC rail on an oscilloscope can show a completely different story! In this video, …

When you cannot get an oscilloscope probe into a tight spot, can you just use a piece of wire? Sometimes. When signal integrity matters, you CAN use a low-cost DIY solder-in probe. …

Analog Discovery Pro from Digilent comes in a 2-channel (ADP3250) or 4-channel (ADP3450) version. These all-in-one instruments work with a PC over USB or can run entirely …
