带有1或2个Keysight 81131A输出模块的Keysight 81130A是具有400 MHz精度的单通道或双通道脉冲数据发生器。
凭借1或2个Keysight 81132A输出模块,Keysight 81130A甚至可成为精度达600 MHz/1.32 Gbps的单通道或双通道脉冲数据发生器。
81130A可提供先进的延迟,并且由于具有PLL振荡器,其脉冲宽度精度超过了81110A的水平。但是请注意,这种高精度的振荡器是不可触发的。相对于81110A,81130A可提供较大的、可分段的内存(64 kbit)。其可计数的循环和序列PRBS特性可为串行数据请求(例如,数据通信信息和初始化例程)提供全面的灵活性。双通道可以是EXORed(即内部添加)。4个独立的定时边沿组合到一起,允许在单一信号中支持任意波形的脉冲。
视输出模块的类型,脉冲的跳变沿可以是可选则的(对于81131A 为800 ps或1.6 ns)或500 ps的固定模式(81132A)。源阻抗为50欧姆,阻抗中的输出电压分别为3.8 Vpp(81131A)和2.5 Vpp(81132A)。
注:
81131A和81132A输出模块可与单台81130A或每个81130A 400/660 MHz / 1.32Gbit/s单通道或双通道脉冲数据发生器结合使用。
通道脉冲数据发生器要求具备下列1-2条输出通道:- Keysight 81131A 400 MHz,3.8 V,50 Ohm至50 Ohm- Keysight 81132A 660 MHz,2.5 V,50 Ohm至50 Ohm
注:只能添加具有相同模块号的输出模块。不能将Keysight 81131A和Keysight 81132A结合在同一台81130A上使用。
