The oscilloscope is rated as the most commonly used electronic debugging tool, widely applied due to its powerful features and versatility. However, with the development of electronic technology, the complexity of testing has greatly increased, and engineers face faster signals, more complex mixed-signal debugging, and even the need for spectrum analysis of many signals. Many … Read more
Follow+Star Public Number, Don’t Miss Exciting Content Editor | strongerHuang WeChat Public Account | Embedded Column The principle of an oscilloscope is simply an ADC conversion, which displays the collected different voltages on the screen. Today, we will discuss what the oscilloscope sampling rate is all about. Example Describing Sampling Rate 1. Storage Depth Imagine … Read more
UART The serial port is asynchronous (does not transmit clock-related data). When two devices communicate using the serial port, they must first agree on a data transmission rate, and the clock frequencies of both devices must be close to this rate. A significant difference in clock frequency on either side will lead to data transmission … Read more

Since there is no reference clock signal, both parties … Read more
Hello everyone, in the last video we shared the decoding of the 1-wire protocol, today let’s take a look at its trigger function. Once the protocol trigger is turned on in the decoding module, after pressing the [Trigger] button, the trigger type automatically changes to the decoded 1-wire protocol. Set the trigger mode to normal, … Read more
In the last article, we explained the major categories of sensors and waveforms. Today, we will discuss the waveforms of actuators and the CAN bus. 01Ignition Waveform Working Principle: When the ECM controls the primary (low voltage) winding, the primary winding magnetizes the core (charging) and stores it; When the primary winding is disconnected, as … Read more
Hello everyone, previously we used the Nth edge trigger function to trigger an under-amplitude signal. So, what exactly is Nth edge triggering? Today we will discuss the Nth edge triggering of the ZDS2022. The Nth edge trigger of the oscilloscope, as the name implies, triggers on the Nth edge, but it is necessary to determine … Read more
1 Background SiC/GaN is increasingly being applied in designs with higher power and voltage, such as motor drivers for electric vehicles (EVs), fast charging stations for electric vehicles, onboard and offboard chargers, wind and solar inverters, and industrial control power supplies/lighting power supplies. As the switching speed of SiC/GaN power devices increases (extremely high dv/dt), … Read more
Today we will introduce the “Lissajous Figures.” The so-called Lissajous Figures are closed curves formed by the superposition of two mutually perpendicular simple harmonic motions. Background Knowledge: What is “simple harmonic motion”? It is somewhat similar to the swinging of a swing, the oscillation of a clock pendulum, or the “Biu” sound of a spring … Read more
