For different channel input signals, sometimes we want one channel signal to meet one condition while another channel waveform meets a different condition, achieving a logical “AND” combination for the channels. For example, how can we trigger channel 1 on a high level while triggering channel 2 on a rising edge? The ZDS2022 oscilloscope not … 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

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
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
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

Not knowing how to use an oscilloscope when repairing a motorcycle is really frustrating when encountering problems A GY6 clone owner reported that sometimes the motorcycle does not accelerate. Since the user … 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
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
