When analyzing the characteristics of a signal, it is necessary to examine the measurement results of various parameters of that signal. The ZDS2022 oscilloscope is equipped with the capability to measure 51 different parameters. This video demonstrates this function in practice. Typically, when analyzing the characteristics of a signal, we rely on the measurement results … Read more
Introduction: In previous videos, we introduced the ROLL mode in the horizontal time base. Now, let’s take a look at the X-Y mode in the horizontal time base. What exactly is it? Figure 1 Oscilloscope Screen Display in X-Y Mode In simple terms, the X-Y mode converts voltage-time display into voltage-voltage display. In fact, in … Read more
Hello everyone, sometimes we encounter such waveforms in waveform measurement. Based on the characteristics of the waveform, we have set the appropriate edge trigger, but the waveform still cannot be displayed stably. What is the reason for this? How should we operate in this case? In the trigger settings, there is a function to set … Read more
Introduction In the failures of medical equipment, issues often arise from certain key chips, leading to abnormal control signals and erratic device actions. In these situations, the oscilloscope becomes a powerful tool, allowing for the rapid identification of key signals and the localization of the root problem. This article analyzes a fault repair case of … Read more
To measure the functionality of an oscilloscope, the trigger module is generally a point of focus. In fact, the triggers used internally in oscilloscopes are divided into analog triggers and digital triggers. The ZDS2022 oscilloscope uses a digital trigger, which results in low signal jitter and high trigger sensitivity, with dynamic adjustment available! We discovered … Read more
The ZDS2022 oscilloscope’s hundred technical exchange meetings are still in full swing. Through communication with a certain customer, it was learned that one of their samples may have abnormal waveforms at the moment of power-up. Today, we will use the ZDS2022 to capture the power-on signal multiple times and observe the real-time comparison of multiple … Read more
During the repair process of welding machines, we often encounter some difficult issues, and at this time, we will use the oscilloscope. Case:NBC270Gas shielded welding with manual welding The fault phenomenon is that the gun outputs gas and feeds wire normally, but does not melt the wire. After excluding problems with the main control board, … Read more
[Title] The motion of charged particles in an electric field is a key and challenging topic in electric field problems. This part integrates knowledge of kinematics, Newton’s laws, curved motion, and energy, making it an excellent question to assess students’ comprehensive abilities. The principle of the oscilloscope is a typical problem within this content, and … Read more
01 What Went Wrong to Study Passive Probes It all started with a question: Can a 1X passive probe be used to match a 50-ohm or 75-ohm system like a coaxial cable? Experienced individuals would immediately answer no, because even a 1X probe has a significant resistor in series. I happened to have a discarded … Read more
