Why ENOB Tells You More than ADC Bit Depth
Why ENOB Tells You More than ADC Bit Depth Thursday, April 16, 2026
Effective resolution matters (way) more than nominal ADC bits in real-world signal measurements. Reality turned into numbers When we look at a picture, our mind makes the connection between the image and the fact that it is a representation of something existing in the real world. We assume it to be an accurate, true representation of a landscape, or a portrait, or anything represented for what …

What is PAM4? Signaling Basics, vs. NRZ, and Testing Monday, December 1, 2025
Mastering PAM4 Design and Test Techniques PAM4 (Pulse Amplitude Modulation 4-level) is a modulation technique that uses four distinct voltage levels to encode two bits of data per symbol. Unlike traditional NRZ, which transmits one bit per symbol, PAM4 doubles the data rate at the same bandwidth, making it essential for next-generation high-speed serial standards. In the course of our careers, we …
将函数发生器与电源结合实现高效测试 Wednesday, November 26, 2025
函数发生器和电源是测试工具库中最重要的两种设备。这两种测试设备都能支持各种项目和活动。通过将电源与函数发生器结合使用，可以进一步扩展这些测试仪器的功能。 但函数发生器到底能做什么？请与我们一起在下文中进行探讨，并探索一台可靠的直流电源可以为您的设备带来哪些帮助。 图1. 偏置三通（Bias Tee）可将信号发生器输出与直流电源输出耦合，但其功率处理能力存在限制 函数发生器的作用 函数发生器是一种电子设备，可在宽频率范围内产生各种电波形。标准波形包括正弦波、方波、三角波等。这些设备也称为任意波形发生器，可测试电子设备在运行过程中可能遇到的不同信号条件。 通过调整函数发生器的设置，可以确定设备或组件在各种条件下的耐受情况。我们可以操纵频率（MHz或KHz）、幅度和带宽等因素。此外，还可以选择创建简单的方波波形或使用复杂波形运行测试。 函数发生器应用广泛。从简单的电路调试到复杂的系统分析 …
