注入经校准的数字抖动以进行容错测量支持注入抖动的Signal Studio是一种能够精确创建周期和/或随机抖动的软件。在与E8267C PSG矢量信号发生器一起使用时，这两个抖动参数可在从250 Kbp/s到20Gb/s的时钟频率范围内使用。本软件借助E8267C PSG先进的IQ模块性能，可根据数字的可重复性提供已校准的附加抖动。先进的 I/Q模块技术可在信号发生器的全部频率范围内提供80MHZ的瞬间带宽。
典型应用在使用从数据波形中恢复或提取的时钟信号来接收或再生数据时，经常需要用到高速数字传输系统和数字I/O总线。数据速率的变化，也就是通常我们所说的“抖动”会造成时钟恢复和数据再生过程的复杂化。为了在出现抖动的情况下也能保证高性能，元器件和系统通常都要符合一套严格的抖动性能标准。对于测试和设计新标准（如CEI、XFP、XFI、UXPi、光纤通道、千兆位以太网、PCI Express 和串行ATA）的工程师而言，E8267C（带有支持抖动注入的Signal Studio软件）已被证明是重复性最强和最精确的抖动源。
如何升级如果您现在已经有了E8267C PSG，那就可以通过订购E8267CK-SP1，把它升级到包含Signal Studio for jitter injection的版本。
