Abstract: In response to the current issues of low sampling rates and poor portability in signal acquisition systems, a design for a high-speed portable signal acquisition system based on FPGA is proposed. This design uses an FPGA chip to control an analog-to-digital converter (ADC) chip for high-speed signal sampling, then stores the data in a … Read more

A multimeter, also known as a multi-tester or volt/ohm meter, is a multifunctional, multi-range measuring instrument. It is the most basic tool in the field of electronic testing and is widely used; it is a measuring tool that personnel in the electronics industry must master. Multimeters are divided into pointer and digital types. A typical … Read more
A multimeter is a common measuring instrument for voltage, resistance, capacitance, temperature, and more. The digital multimeter is easy to operate, rich in functions, and the display screen directly shows the required measurements for DC voltage, AC voltage, DC current, AC current, resistance, capacitance, etc. Today, we will take the clamp multimeter as an example … Read more
A multimeter is an instrument that can measure various parameters, such as alternating current (AC) or direct current (DC) voltage, AC or DC current, resistance, temperature, capacitance, and more. Modern digital multimeters have adopted digital and logic technologies, becoming smaller in size and featuring more built-in functions. By introducing digital technology, digital multimeters can provide … Read more
Oscilloscope, as its name implies, is a machine that displays waveforms, and it is also known as the “eye of the electronic engineer.” Its core function is to display the actual waveform of the measured signal on the screen, allowing engineers to locate problems or evaluate system performance, among other tasks. Its development has also … Read more
