示波记录仪
Yokogawa的波形记录仪可捕捉高速瞬变、低速趋势或介于其间的任何信号。波形记录仪是灵活、强大的多通道测试和测量解决方案，将高精度示波器和传统有纸或电子波形记录仪的优点集于一身。
横河波形记录仪是一款功能强大的便携式数据采集录波仪，可以捕捉与谐波分析瞬态事件，显示长达200天的趋势波形。通过插拔模块，可以灵活组合电信号与物理信号(传感器信号，如CAN、LIN和串行总线)的测量，还能实现实时功率运算的触发。
让我们来感受世界一流的横河录波仪：自1988年首款机型面世以来，YOKOGAWA一直不断创新，致力于电力电子、机电一体化和新能源等前沿行业专用录波仪的研发，近期又推出全新DLM系列录波仪，既有面向低成本市场的4CH MSO示波器——DLM2000系列，也有业界唯一的全新8CH MSO波形记录仪。
严苛的测量条件需要高性能与灵活的解决方案。这就是DL350示波记录仪的设计理念。 DL350与其它示波记录仪共用同样的18种插拔模块，电池供电使其易于携带，可在受限的空间中使用。
DL350最多提供8路模拟量和16路数字量通道，采样率可达100MS/s，最大绝缘电压1KV，最高分辨率16位，支持多种模块，可灵活配置，适用于各种长时间和瞬间变化波形的测量。
可充电电池的使用，不仅使得现场测试成为了可能，它与主电源配合，还起到了UPS的作用。

This video demonstrates how to measure transient phenomena on power signals using the Yokogawa Test&Measurement PX8000 Precision Power Scope.
In several applications, especially those testing AC power to a standard such as IEC61000-3-11, the voltage and current signals must be monitored to confirm there are no major dips and/or swells in the signal. This can be done with instruments capable of reporting rms values, including power analyzers, traditional oscilloscopes, and some data acquisition systems.
To test to a standard, however, the instrument must have an accuracy spec that is traceable back to a national standard of calibration such as ISO17025 or NIST.
