碩士 === 國立高雄應用科技大學 === 電機工程系博碩士班 === 106 === Under the rapid development of semiconductor manufacturing technology, ac-cording to Moore's Law, the number of transistors in an integrated circuit is multiplied every 1.5 years, so that the integrated circuit in the hardware circuit continues to develop toward small size, high speed and low power. The oscilloscope is the importance of the hardware engineer. Just as the eye is important to human beings, people can observe this complex and changing world through the eyes, but the "electricity" is invisible, so the scientists invented the oscil-loscope. To solve this problem, the electrical signal is converted into a waveform to represent, the voltage and time changes can be understood, the information represented by the electrical characteristics is analyzed in advance, and the electronic technology is pushed to the endless future through the oscilloscope. However, the analog oscilloscopes that were invented in the early days could not watch the waveforms of transient transients and record retention data files, which could not meet the needs of engineers. With the advancement of technology, the birth of digital storage oscilloscopes changed the habits of engineers. Using analog-to-digital conversion (ADC) technology to improve bandwidth, sampling rate, and memory depth, special trigger circuit, accurate automatic parameter measurement, multiple mathematical operations, and practical remote monitoring, greatly enhance the use of the oscilloscope Functions, whether complex and difficult to understand signals, or unusually difficult waveform changes, can be easily identified to solve the problem. The main content of the thesis is to explore the evolution process of the oscilloscope, understand the specifications, basic operations and advanced industrial demand applications, and finally explore the future development trend.
