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 …

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 …
