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 arbitrary waveform generator and a function generator?
February 14, 2025 387
The Function Generator provides a preset list of waveforms or code patterns that it can generate. In a function generator, the user can change waveform parameters such as frequency, amplitude, and offset, as well as add simple distortion. Arbitrary waveform generators are more complex and can emulate real-world signals. Arbitrary waveform generators utilize pre-stored digital data to generate these waveforms,...

What is a current probe?
February 14, 2025 477
Many people use digital multimeters to easily measure current, voltage, resistance, etc. However, there is a drawback to using a digital multimeter to measure current, namely: the circuit must be disconnected and the digital multimeter must be connected in series with the circuit under test in order to make the measurement. In this case, a current probe can be used instead of a digital multimeter to make measurements. Since the electrical connection of the circuit is no longer required, the current probe is more time-consuming...

What is a function/waveform generator?
February 14, 2025 403
A function generator is an electronic test device that generates a variety of standard waveforms for a device under test (DUT), such as sine, square, ramp, or sawtooth waveforms. In circuit design and circuit boards, testing often requires the use of controlled signals to simulate routine operations. Testing physical systems and sensors often requires stable and reliable signals that are as low as a few microvolts and may be as high as...

What is IQ modulation?
February 14, 2025 242
In-phase quadrature modulation (IQ modulation) is the main modulation scheme used in communication applications. It is popular because of its efficient use of bandwidth, meeting the increasingly urgent need for bandwidth in a world where data volumes are growing exponentially. It is important to test with simulated IQ signals because designers are always faced with a lack of bandwidth in an interference-ridden spectrum. Example...
