UART Serial Bus Protocol

UART Serial Bus Protocol

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

Using Oscilloscope to View UART Waveforms

If you don’t want to miss my updates, remember to click the top right corner – view public account –set as starred, and send you a little star Source: Breadboard CommunityUART is an asynchronous full-duplex serial communication protocol consisting of two data lines, Tx and Rx. Since there is no reference clock signal, both parties … Read more

Oscilloscope Practical Series: 1-Wire Protocol Trigger

Oscilloscope Practical Series: 1-Wire Protocol Trigger

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

Understanding Waveforms in 3 Minutes: Actuators and CAN Bus Analysis

Understanding Waveforms in 3 Minutes: Actuators and CAN Bus Analysis

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

Practical Oscilloscope Video 35: Nth Edge Triggering

Practical Oscilloscope Video 35: Nth Edge Triggering

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

Correct Measurement of Signals in SiC/GaN Power Electronics Systems

Correct Measurement of Signals in SiC/GaN Power Electronics Systems

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

Understanding Lissajous Figures

Understanding Lissajous Figures

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

The Role of Oscilloscopes in Radar Analysis: Triggering

The Role of Oscilloscopes in Radar Analysis: Triggering

Introduction to Oscilloscopes Oscilloscopes are fundamental tools for detecting voltage variations over time. They are particularly suitable for displaying the shape of baseband pulses. The performance parameters of oscilloscopes can be traced back to the characteristics of early radar pulses. Real-time oscilloscope bandwidths can reach up to 33GHz, designed to capture and display repetitive or … Read more

Oscilloscope Practical Series 14: Crystal Oscillator Measurement

Oscilloscope Practical Series 14: Crystal Oscillator Measurement

When observing the waveform on the crystal oscillator pins with an oscilloscope, it often happens that the crystal oscillator waveform is not visible on the screen or the characteristics of the waveform are incorrect. This article explains the correct method for measuring the crystal oscillator waveform with an oscilloscope through practical operations. Through the previous … Read more

Measuring Positive Duty Cycle with Oscilloscope

Measuring Positive Duty Cycle with Oscilloscope

How do we calculate the positive duty cycle for such a narrow pulse on the screen? We set the horizontal time base to 200us/div, allowing us to observe its two cycles. Since the pulse is too narrow, using traditional manual measurement with cursors is not the best option. What methods can the ZDS2022 provide? The … Read more
