Oscilloscope Input Impedance Matching Issues – Experience Sharing

When testing a signal with an output impedance of 50Ω using a Pico oscilloscope, a 50Ω to 1MΩ direct terminal is required. Recently, during an on-site test with a client, I found that the waveform oscillated severely, as shown in Figure 1 (red box), making it impossible to conduct accurate data analysis. Figure 1 Severe … Read more

Oscilloscope Duty Cycle Search: Practical Guide

Hello everyone, in the previous episode of our 100-episode practical video series, we shared the pulse width search function of the ZDS2022 oscilloscope. The oscilloscope’s search function is practical and convenient. However, some users are still not very familiar with the search function of the ZDS2022 oscilloscope. In fact, the ZDS2022 oscilloscope has a powerful … Read more

Oscilloscope Practical Series 21: Slope Measurement

During the technical exchange meetings of oscilloscopes, we learned that some customers need to understand the rise slope of CAN signals. They usually measure some values and then calculate manually. The ZDS2022 oscilloscope will save you a lot of time by displaying the results directly without manual calculations! The operation is very simple. First, connect … Read more

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

Oscilloscope Practical Series Episode 9: X-Y Mode

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

Oscilloscope Practical Series 55: Trigger Hold Off

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

Application of Oscilloscope in SOMATOM CT Maintenance

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

Oscilloscope Practical Series 48: Trigger Sensitivity

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
