What is a function/waveform generator?

February 14, 2025common problems 4000

函数发生器是一种电子测试设备，可为被测器件（DUT）生成多种标准波形，例如正弦波、方波、斜波或锯齿波。在电路设计和电路板中，测试通常需要使用可控信号来仿真常规操作。测试物理系统和传感器通常需要稳定可靠的信号，这些信号的电压最低只有几微伏，最高可能有几十伏甚至更高。

通过提供激励信号或已知的输入信号，我们能够观察器件在不同条件下做出的反应。被测器件展现出来的特性是否符合预期？在性能崩溃之前它有怎样的容忍度？

您可以将已知的正常信号输入被测器件并监测输出，从而评测被测器件的性能。波形发生器的输出必须纯净且稳定，应当能代表器件的最终应用将会使用的真实信号。

What is ATE System Power?
February 14, 2025 480
Automated Test Equipment (ATE) system power supplies are programmable power supplies designed specifically for ATE systems. Form factor is critical. ATE power supplies with higher power densities take up less rack space, reducing the factory floor space required for test equipment. The ATE power supply is a programmable power supply designed specifically for ATE systems.

How do I measure voltage? If you use a multimeter, anyone can measure it easily ■ Summary Since voltage is not visible to the naked eye, it is not possible to confirm "how much voltage is flowing through a circuit at a glance". However, the circuits of electronic devices have a set voltage for normal operation, and if the voltage is too high, it may lead to product malfunction or personal injury. In addition, ...
