An eye diagram, as the name suggests, is a graphical representation that resembles an eye. How is it formed? This brings us to the persistence mode of an oscilloscope. The refresh rate of our naked eyes is only 60Hz, which sometimes makes it difficult to detect occasional abnormal signals. The persistence mode can superimpose and … 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
Problem Statement Hello, Teacher Zhuo. I observed a strange phenomenon while testing my new motor driver with the oscilloscope: 1. When I set the oscilloscope to a time base on the same order of magnitude as the PWM period, I could measure a standard PWM waveform. However, when I increased the time base, I noticed … Read more
