There are many key indicators for measuring the quality of an oscilloscope testing system, and the “Effective Number of Bits (ENOB)” is crucial for understanding the entire measurement system. This article will discuss the effective bits of oscilloscopes, the impact of ENOB on actual signal testing, and provide methods for solving it using EXCEL in … Read more
The oscilloscope is the most common instrument for electronic engineers, and many people compare it to the “eyes” of an engineer, which is enough to illustrate how important oscilloscopes are to engineers. How is the signal displayed on the oscilloscope screen? On the oscilloscope, the signal is transmitted through a series of resistors and capacitors … Read more
X-Y display, also known as a scatter plot or cross-plot, provides a method for plotting one trace against another. This type of display can be used to compare two waveforms and show the relationship between them. A third parameter, such as frequency of occurrence, can be added to the two-dimensional plot as a variation in … Read more
The digital multimeter is a powerful assistant for measuring electrical signals. Although it is called a “universal” meter, its common functions are limited to measuring voltage, current, and resistance. Voltage and current measurements also include AC and DC ranges. In addition, some multimeters can measure inductance, capacitance, continuity, diode forward voltage, transistor current gain, counting … Read more
01 DM3068 Digital Multimeter 1. DM3068 Digital Multimeter This is a RIGOL six-and-a-half digit digital multimeter, model DM3068. Yesterday, while using this multimeter in DC mode to test the DC signal in a square wave signal, I encountered a major pitfall. The frequency of this square wave signal is 1kHz, with a low level of … Read more
Hello everyone, in this video we will introduce the most commonly used Lissajous measurement method in X-Y mode. First, we will connect two sine wave signals with the same frequency but different phases to Channel 1 and Channel 2. After capturing the waveform, you can see that the phase difference between the two signals is … Read more
The oscilloscope is one of the most important testing instruments in modern electronics, and its applications are also very broad in other fields. The main use of an oscilloscope is to observe and measure the waveforms of electrical signals. Additionally, using its image display function, users can directly measure parameters such as the amplitude, frequency, … Read more
An oscilloscope is an indispensable instrument in modern electrical repair. With it, technicians can quickly and accurately locate common faults, making the proper and skilled use of an oscilloscope a required skill for electrical repair personnel. Although there are various models, specifications, and types of oscilloscopes, their basic structure and function are quite similar. This … Read more
