In addition to measuring basic parameters such as voltage, current, resistance, capacitance, and inductance, digital multimeters can be adapted for various uses, expanding their functionality to achieve a multi-purpose tool. Here is a method for using a digital multimeter to determine internal breakpoints in wires and cables: when there is an internal break in the … Read more
What is the purpose of grounding an oscilloscope? Grounding serves as the reference point for all voltage measurements, ensuring that there is a known 0V voltage point in the circuit. This is crucial for ensuring measurement accuracy, suppressing noise interference, and ensuring measurement safety. It can be observed that the power cord of a desktop … Read more
Oscilloscope probes come in many types based on electrical performance and usage scenarios (as shown in the figure below). However, their interface types mainly depend on the design of the oscilloscope’s input channels and the compatibility of the probes. Below are common interface types and their characteristics: 1.BNC Interface Most Common Type, widely used in … Read more
