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

The oscilloscope is one of the most important testing instruments in modern electronics, and its applications are also very broad in other fields. The main use of an oscilloscope is to observe and measure the waveforms of electrical signals. Additionally, using its image display function, users can directly measure parameters such as the amplitude, frequency, … Read more
1. Introduction Originally, I needed to use the front end of the oscilloscope probe to create a shielded connection, but unexpectedly, when disassembling the front end, I discovered a strange part inside. It seems there is a small capacitor within this structure. 2. Internal Structure To minimize the impact on the circuit being measured, the … Read more
