Before learning how to use an oscilloscope to reduce noise, let’s first understand how noise in oscilloscopes arises. Many people who have just transitioned from analog oscilloscopes to digital oscilloscopes may complain that the waveforms measured by their new oscilloscope are not as clear as those from their old analog oscilloscope, even doubting whether their … Read more
Power supply ripple testing is a crucial parameter in power quality detection, but accurately measuring power supply ripple has become a challenge for engineers. How can we overcome this problem? In fact, after searching for it thousands of times, the solution is right there in front of us. Because a DC regulated power supply is … Read more
May 2020 Introduction to the Equipment The pico automotive oscilloscope perfectly combines hardware and software, making it one of the most advanced automotive fault diagnostic devices available today. As shown in Figure 1, it mainly consists of the oscilloscope host (such as pico scope 4425, pico scope 4823, etc.), diagnostic software (pico scope 6 automotive … 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
Today, I will share with you the scrolling mode of the ZDS2022 oscilloscope. When it comes to scrolling mode, you might find it unfamiliar. Let’s first understand what scrolling mode is all about. Figure 1 Screen Display in Scrolling Mode In scrolling mode, the oscilloscope continuously samples the waveform without any dead time. The waveform … Read more
A digital real-time oscilloscope is a type of digital oscilloscope (DSO), also known as a “single-shot” oscilloscope, which captures signals in real-time at a sampling rate far exceeding the signal bandwidth (generally over 2 times, ideally over 5 times), making it easy to observe high-speed single-shot signals. There are three important technical specifications that define … Read more

It can measure voltage, signal waveforms, and can also generate common voltage waveforms for circuit testing. Keywords：STC，DSO，Handheld Mini Oscilloscope In Make Your Own Oscilloscope(Mini DSO) With STC MCU Easily, … 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
