View Full VersionWhat is the purpose of an oscilloscope?
测试工程师和开发人员在研究和开发、验证、质量保证以及电子系统、电路板和集成电路的故障排除或调试过程中使用示波器来显示、可视化图形和分析电信号。示波器在所有行业的各种应用和技术中发挥关键作用，包括高速数字电子、光通信、射频、电力电子、汽车和航空航天及国防。
示波器是观察、分析或记录电信号行为的关键测试仪器。在电子实验室中，示波器的一些具体用例包括测量电压波形、分析电子信号、检测不需要的噪声和串扰以及评估电力系统中的有害瞬变。
在高速信号分析中，示波器可以通过显示和测量眼图来测量信号完整性，包括眼高和眼宽。混合信号示波器可以通过显示测量的数字信号的逻辑状态和时序来帮助调试数字电路。高级示波器甚至可以帮助模拟理想的参考接收器进行发射机测试，使用光电转换器测量光纤信号，并分析射频信号。
由于其多功能性，示波器根据应用的不同具有许多不同的性能水平和软件功能。它们是电子开发、故障排除和分析中不可或缺的工具。

What is the difference between an oscilloscope and a spectrum analyzer/signal analyzer?
97We usually use time as a frame of reference, focusing on when certain specific events will occur. This includes electrical events. Oscilloscopes allow you to view the instantaneous value of a particular electrical event (or the voltage value of some other event converted by an appropriate transducer) over time. In other words, we can use an oscilloscope to view the waveform of a signal in the time domain. Fourier theory...

What is the importance of waveform sequencing?
338Waveform sequencing lets you create multiple configured waveforms that contain multiple common segments. Sorting lets you build complex, long waveforms using as little instrument memory as possible. Waveform sequencing lets you save storage capacity by replaying shorter waveforms at different locations on the signal as needed. Many tests require long waveform memory records. The required record length...

How does a spectrum analyzer work?
479A signal that looks very complex in the time domain behaves quite differently in the frequency domain. Time domain measurements show an impure sine wave. Without frequency domain measurements, it is still impossible to know the source and frequency of the second harmonic. Spectral analysis can show the spectral components individually, thus revealing the source of the interference. The information provided in the time domain (e.g., the signal pulse on...
