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
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
Jitter is the short-term variation of a digital signal’s timing relative to its nominal value. There are two main types of jitter: random jitter and deterministic jitter. Random jitter is unbounded, meaning its value continues to increase as the measurement duration increases, and it is related to random processes such as noise. Deterministic jitter, on … Read more
Hello everyone, the oscilloscope, as a versatile measuring instrument, is fundamentally designed for measurement statistics. The oscilloscope on your lab bench may have been used many times with various functions, but have you truly paid attention to its core measurement statistics function? Is this function genuinely usable and reliable? The ZDS2022 oscilloscope, after incorporating most … Read more
Improving the accuracy of an oscilloscope is not difficult, but attention to detail is required. This article will explore various methods to enhance oscilloscope measurements. Using Multiple Grids to Maintain Dynamic Range A common use of an oscilloscope (4 channels) is to sacrifice one-quarter of its dynamic range by attenuating the amplitudes of several signals … Read more

In the field of electronic engineering, oscilloscopes are important tools for analyzing signal characteristics. When it is necessary to observe and stabilize the waveforms from two different signal sources simultaneously, how can electronic engineers achieve this? Below are the specific steps to efficiently stabilize the display of both signals on the oscilloscope. 1. Check Signal … Read more
The national standard of China (GB7665-2005) defines a sensor as: “a device or apparatus that can sense the measured quantity and convert it into a usable output signal according to certain rules.” Sensors, as an important means of information acquisition, along with communication technology and computer technology, constitute the three pillars of information technology. Below, … Read more
When selecting a DAQ device, have you considered these influencing factors? —— The choice of architecture and robustness will determine the applicable scenarios of the system, such as a controlled laboratory or unpredictable field conditions. —— The selected bus can determine not only the throughput and latency of the DAQ system but also the portability … Read more
