产品简介
R&S®RTA4000 示波器专用于提供一流的信号完整性和快速响应的超大深存储。“十”力钜献,显示更多信号细节。
1 概述对于示波器用户而言, 带宽、 采样率和存储深度是最重要的三种规格。 本应用指南将重点介绍选购示波器时需考虑的存储深度。 选购具有深存储的示波器, 可以在排查故障和进行调试时节省大量时间。
评估示波器存储深度的性能和质量, 比只关注一种参数更为有用。 了解存储深度的属性和优点, 能够确保所选示波器满足需求和应用要求。
► 示波器采集存储的定义► 存储和其他示波器参数的关系► 深存储的作用示例
2 采集存储定义采集存储也被称为存储内存(M)或记录长度(RL), 表示示波器每次采集时能够存储的采样点数量。 采集存储以采样点为单位, 通常写作point (例如Mpoints) , 以避免混淆采样率(Msample/s)和存储深度(Msample)。 存储深度为示波器的采样率和采集时间之积。
