保护可编程直流电源: 防止电感、电容和振荡负载的不利影响 Tuesday, October 28, 2025
连接直流电源与负载看似简单,但在某些复杂场景下可能充满挑战。尽管电源制造商设计产品时已确保其在多种负载下的稳定性,但某些负载特性仍可能带来风险,甚至损坏电源的输出级。感性负载、容性负载以及负载电流快速变化的负载可能引发振荡,危及电源和负载设备。此外,感性和容性负载会向电源反馈能量。本文将探讨直流电源可能面临的各类危险负载类型,并提供解决方案,以确保电源可靠运行并保护负载安全。 感性负载: 感性负载(如电机、螺线管和机电继电器)可能成为能量源,向电源反馈能量并造成损坏。当电压和电流施加到感性负载时,会建立磁场并储存势能。在电源断开时,磁场崩溃,产生反向极性的电压尖峰。这种反向电动势可能损坏电源的输出级。 为保护电源,可在电源输出端并联一个反向偏置二极管,称为续流二极管或飞轮二极管。当电源关闭时,该二极管为感性负载产生的电流提供通路,从而保护电源免受反向电动势冲击 …
New De-embedding, Embedding, and Equalization Software for High-Speed Systems Verification and Compliance Test.
New De-embedding, Embedding, and Equalization Software for High-Speed Systems Verification and Compliance Test Tuesday, October 28, 2025
Verification and compliance of high-speed systems require visibility across the full signal path—from DUT to oscilloscope input. This means de-embedding test fixtures and interconnects, embedding realistic system conditions, and, in some cases, applying receiver equalization to emulate Tx/Rx behavior. Only then can you confirm both compliance and real-world performance. Tektronix’s new Signal …

Temperature Calibration and Why It Matters: Accuracy, Safety, and Compliance Monday, October 27, 2025
In virtually every industry, from pharmaceuticals to food processing and aerospace, temperature is a critical variable. The success of a process, the quality of a product, and even operational safety often depend on precise temperature control. But how do you ensure the thermometers, sensors, and controllers you rely on are telling the truth? The answer is temperature calibration. This blog …

The Advantage of Instrument Adjustments with Tektronix Factory Calibration Service Friday, October 24, 2025
For engineers and technical managers, maintaining the accuracy and traceability of test and measurement equipment is essential to ensuring product quality and regulatory compliance. One often-overlooked advantage of choosing Tektronix Factory Calibration over third-party providers is the inclusion of instrument adjustments at no additional cost—a benefit that becomes especially critical when …
Precision Matters  The Critical Role of Calibration in High-Performance Electronics
Precision Matters: The Critical Role of Calibration in High-Performance Electronics Friday, October 17, 2025
Calibration is the cornerstone of precision and reliability in high-performance electronic test equipment. Unlike mechanical or dimensional calibrations which are based on physical disciplines, calibrating advanced electronic systems requires extensive electrical circuitry understanding. In high-speed systems, errors—like a ±2.00 dB deviation—can lead to critical issues such as signal noise …

Calibration of Measurement Instruments Precision In Practice Thursday, October 16, 2025
In advanced electrical engineering, measurement accuracy is foundational to system design, validation, and compliance. Whether you're characterizing high-speed digital interfaces, validating power integrity, or performing EMI diagnostics, the calibration of measurement instruments safeguards that your data is not only accurate—but also traceable, repeatable, and defensible. At Tektronix, we view …
FastAcq on the 2 Series MSO
Uncover Glitches with FastAcq on the 2 Series MSO Wednesday, October 15, 2025
With a capture rate of over four million waveforms per second, you’ll see blinks of glitches, catch the slightest jitter, and find the rarest faults. Even when these anomalies are hidden so well between clock edges and protocol pulses, a high capture rate will keep you from flying blind. In this blog, we’ll explore how the new FastAcq feature on the 2 Series MSO can enhance your debugging …
Service as Strategy: Evolving Our Global Model Thursday, October 9, 2025
In a time when supply chains remain unpredictable, engineering teams are under constant pressure to deliver more quickly, and new technologies—from AI-optimized semiconductors to quantum systems—are redefining what’s measurable, one thing remains constant: test and measurement must keep up. At Tektronix, we believe keeping up isn’t enough. We need to move faster than the pace of innovation, so our …
Service Delivery is Evolving-Here's What It Means for You Thursday, October 9, 2025
Your programs depend on precision. Maintenance windows, calibration cycles, and instrument availability all keep your schedules on track. As Andy Maloney recently shared, Tektronix is evolving how we deliver service for our customers. In the Americas, that evolution is centered on flexibility—especially for customers who manage instruments from multiple OEMs. We’re focused on making access easier …
Power Regeneration in Electronic Loads
Power Regeneration in Electronic Loads: The Engineer’s Guide to Energy-Efficient Test Systems Tuesday, September 30, 2025
As industries accelerate their shift toward decarbonization and energy efficiency, engineers are under growing pressure to reduce waste during testing. Power regeneration in electronic loads offers a smarter, greener way to recover energy instead of dissipating it as heat. This hub blog explains what regenerative loads are, why they matter, and how they connect to broader power testing strategies …
