Editor’s Note: Oscilloscopes are almost an essential tool for electronic engineers, but not every engineer can use them effectively. This article shares seven common mistakes encountered when using oscilloscopes. These may align with what you’ve seen or differ, but of course, this is subjective. Ideally, all probes should be a wire that does not interfere … Read more
This article will introduce the types and uses of various probes. What is a probe: An oscilloscope is the most commonly used measuring instrument by electronic engineers, and the oscilloscope probe is undoubtedly the most commonly used accessory for the oscilloscope. The oscilloscope probe is the electronic component that connects the measured circuit to the … Read more
Understanding Oscilloscope Probes The measured signal cannot be directly connected to the oscilloscope, so a device is needed to establish an electrical connection between the test point and the oscilloscope. Depending on the needs, this device can be a simple wire or a more complex circuit. The device responsible for linking the test point and … Read more
Connection Method 1: Not recommended, interference leads to continuous bugs. Solution 2: Connect the passive termination resistor as shown in the figure: recommended. Connection Method 3: Connect 5V active termination resistor: Incorrect Connection Method: Error 1: The bus must be connected in a linear fashion, not in a star configuration. Error 2: Missing termination resistors. … Read more
