新型IsoVu™ 隔离电流探头:为电流测量带来全新维度 Wednesday, November 27, 2024
示波器测量电流的常见方法包括使用电流互感器、罗氏线圈和霍尔效应钳式探头。按规格要求使用时,优质磁探头的测量结果非常准确。因为不需要破坏原有电路,因此用于测量在电线或测试回路中流动的电流也很方便。然而,磁探头存在一些固有的局限性。在本文中,作者将介绍针对基于分流器进行电流测量而优化的探头属性,并探讨 IsoVuTM隔离电流探头特别适用的两种应用。 如上所述,使用磁探头测量时需要一根线圈。由于物理限制或电路的敏感性,有时无法使用这种线圈。由于磁性材料的特性,即使是高端钳式电流探头,带宽也被限制在 100 MHz 左右。尽管人们可能会认为非接触式探头不会影响电路性能,但磁探头插入阻抗的意外影响却让许多工程师困惑不已,因为该阻抗在全带宽下可能接近 1 Ω。   图 1当有电线或测试环路可用、插入电感可以容忍且带宽限制在 100 MHz 左右时,使用示波器钳式交流/直流电流探头非常方便 …
Engineer using a 4 Series B MSO oscilloscope with motor drive analysis software to analyze the 3-phase output of a motor drive used in an electric vehicle
Bringing More Power Analysis Tools to Engineers’ Benches with the 4 Series B MSO Thursday, July 18, 2024
It can be challenging to consistently measure the performance of AC-DC and DC-DC converters. These challenges have become even greater as designers work to transition from silicon-based power converters to wide bandgap semiconductors such as silicon carbide (SiC) and gallium nitride (GaN). Designers of 3-phase systems such as motor drives face additional complexity. Thankfully, help is available …
Low frequency response curves with AC coupling or DC reject turned on, for different types of probes
Probe Points: Understanding Low Frequency Response Friday, June 28, 2024
The Practice of AC Coupling and DC Reject Modes The practice of AC coupling the scope input or using a probe with DC reject capability is very common when looking at noise and/or ripple of DC power rails. Anytime there is insufficient DC offset available, then users often elect to use AC Coupling or DC Reject settings. With the focus on clean power, we see users more interested than ever before in …

The Importance of Double Pulse Testing for Designing Today’s Power Converters Thursday, June 27, 2024
​The field of power electronics is rapidly transitioning from the use of silicon semiconductor materials to wide bandgap semiconductors such as silicon carbide (SiC) and gallium nitride (GaN). One of the most common applications of GaN and SiC semiconductors is to enable smaller, faster and more efficient designs of power converters. Power converters operate at multiple stages throughout the power …

MIMO 雷达系统测试工具和技术 Friday, March 1, 2024
多输入多输出 (MIMO) 等现代技术要求宽带宽、相位一致和多通道分析。MIMO 雷达系统中的天线元独立运行,可覆盖较宽(通常为 180 度)的视场,无需进行定向调整。因此,扫描时间显著缩短。MIMO 雷达利用时间、频率或编码技术,在接收器元素中对每个发射信号进行区分,从而提取目标属性。 宽带示波器,例如泰克 DPO70000SX 或 MSO/DPO70000DX 系列示波器,专为实现宽带宽和相位一致而设计,因此是一种理想的仪器。它支持中心频率、频谱宽度和分辨带宽 (RBW) 等参数的独立设置,与用于多通道控制和分析的 SignalVu VSA 5.3 软件版本配合使用,所得测试系统便是验证 MIMO 相控阵雷达的绝佳选择。对于获取可能具有不同中心频率、时隙或调制参数的信号,独立设置非常必要。 用于频谱分析的脉冲统计数据 TDM MIMO 雷达为每个元素分配一个时隙。对于每个通道的信号 …

3 Things to Consider When Synchronizing Oscilloscopes for Higher Channel Count Tuesday, January 16, 2024
When constructing a test system, there might be a need to measure more signals than a single oscilloscope can capture with its available channels. To increase the number of oscilloscope channels in a test system, a common approach is to combine multiple oscilloscopes. Multi-channel measurements find application in various scenarios, such as capturing complex particle physics experiments, measuring …
