縮短理論與現實之間的差距 Wednesday, November 4, 2026
一名工程系學生在對射頻發射器進行疑難排解時，注意到了一些奇怪的情況。當他站在系統旁邊時，系統運作正常。當他走開幾英尺後，效能就發生了變化。 設計沒有改變。計算結果並沒有改變。然而行為是不同的。 最終，問題的根源變得清晰起來。房間裡的螢光燈產生了干擾。站在電路旁邊時，學生的身體在無意中起到了遮蔽作用。當他走開時，干擾又回來了。 我第一次從美國一所主要研究型大學的工程學院聽到這個故事，我經常想到它，因為它捕捉到我在職業生涯中多次看到的一些東西。理解理論只是理解系統在實踐中如何運作的開始。縮短這一差距是工程的重要組成部分。 在我職業生涯的大部分時間裡，我看著工程團隊應對越來越複雜的挑戰。改變的不是工程師的學習能力。改變的是技術週期的速度。電源架構正在快速演進。AI 基礎設施正在呈指數級擴張。新的寬能隙半導體材料正在改變資深工程師花費數十年才掌握的設計。 在現代工程中 …

Four Innovations that Accelerate High Channel-Count, High-Precision Semiconductor Testing
加速高通道數、高精密度半導體測試的四項創新 Monday, July 13, 2026
半導體測試工程師持續面臨提高輸送量和涵蓋範圍的壓力，同時不影響量測準確度或裝置安全性。增加通道數量有助於提高輸送量—透過平行測試多個 DUT，同時也提升涵蓋範圍。然而，當工程師們擴展多通道、高精密度測試系統時，會面臨一些突出的工程挑戰： • 管理更多通道和更多儀器 • 來源和量測之間更緊密的時序協調。 • 運用 AI 和現代工具來進行高效軟體開發 • 維持或提升量測精度 Tektronix MP5000 系列模組化精密測試系統採用重大創新設計，專為此現實情況協助測試工程師克服這些挑戰。： 1. 高通道密度有助於管理機架空間。 2. 彈性的儀器上指令碼，可降低通訊開銷。 3. 進階觸發和序列，實現決定性計時。 第四。硬體交錯觸發與同步化 本文說明其運作方式，以及它們如何有助於半導體測試的生產量和覆蓋率。本文也說明 MP5000 和 3706A …

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 …

Understanding ENOB (Effective Number of Bits) in Test and Measurement Equipment Wednesday, November 19, 2025
ENOB — the Practical Measure of ADC Accuracy Leading-edge electronic systems are becoming faster, denser, and more complex. Engineers working on next-generation wireless, automotive radar, medical imaging, and high-speed computing are all pushing the boundaries of performance. As a result, testing these systems isn’t easy - signals are higher in frequency, denser in modulation, and more sensitive …

Humidity Calibration Explained – Methods, Standards and Industry Best Practices Wednesday, November 5, 2025
In countless critical environments—from pharmaceutical cleanrooms and food storage facilities to semiconductor manufacturing and archival preservation—precise humidity control isn't just a preference, it's a necessity. Inaccurate humidity readings can lead to compromised products, inefficient processes, and costly compliance issues. Humidity calibration is your assurance that your measurements are …

Torque Calibration Explained: Processes, Frequency, and Provider Selection Wednesday, November 5, 2025
From automotive assembly lines to aerospace engineering, the precise application of torque is essential for safety, reliability, and product quality. Torque tools—wrenches, screwdrivers, and analyzers—must deliver exact rotational force to fasteners. But how can you ensure their accuracy over time? The answer lies in rigorous torque calibration. This guide provides an in-depth exploration of …
