How to Distinguish Pitch, Loudness, and Timbre from Waveforms

How to Distinguish Pitch, Loudness, and Timbre from Waveforms

1. The Three Elements of Musical Sound 1. Pitch refers to the highness or lowness of a sound, determined by frequency. In physics, the speed of an object’s vibration is described by the frequency, which is the number of vibrations per second. A faster vibration results in a higher frequency and a higher pitch; a … Read more

Audi's Fault: Burning Money Faster than Circuit Boards!

In recent days, several Audi vehicles have come into the shop, all displaying the warning “Battery Voltage Low.” The car owners initially thought, “It’s fine, we can still drive!” But as they drove, the car suddenly broke down and turned into an electric deadweight! Time to call a tow truck! Using a diagnostic tool, the … Read more

Practical Applications of Oscilloscopes: Precise Control of Exposure and Color Cast with Waveform and Vectors

Practical Applications of Oscilloscopes: Precise Control of Exposure and Color Cast with Waveform and Vectors

Our eyes can deceive us, but data never lies. Today, I will teach you how to use DaVinci’s built-in “Oscilloscope Duo”—the waveform and vector scopes—to precisely control the brightness and color of your footage, just like playing a puzzle game. All operations have been tested on the free version of DaVinci 18, so follow along … Read more

Understanding Norm and Auto Modes on Oscilloscope

Understanding Norm and Auto Modes on Oscilloscope

One of the fundamental issues when using an oscilloscope is how to stabilize the displayed waveform. This article explains what norm and auto mean on the mode selection switch of an oscilloscope. This involves the triggering operation, which is a skill that is relatively difficult to master when using an oscilloscope because it relates to … Read more

Oscilloscope Operation Special Edition 8: One-Key Scroll

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

USB Digital Real-Time Oscilloscope: 5000D Series Adjustable Vertical Resolution

USB Digital Real-Time Oscilloscope: 5000D Series Adjustable Vertical Resolution

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
