    HIGHLIGHTS

    • 码型发生器和误码检测器的数据速率为150 Mb/s 至 7 Gb/s 或 150 Mb/s 至 12.5 Gb/s
    • >0.5 UI 经校准、综合一致的抖动注入:RJ、RJ-LF、RJ-HF、PJ1、PJ2、SJ、BUJ、ISI、正弦干扰、SSC 和剩余 SSC
    • 出色的信号性能和灵敏度
    • 内置时钟数据恢复功能和可调节、一致的环路带宽
    • 用于正向时钟设备的半速率时钟和可变占空比
    • 可测量 BER、BERT 扫描、RJ/DJ 分离的 TJ、眼图、眼图模板、BER 轮廓、自动抖动容限,并可捕获码型
    • 使用 60 种模块码型序列发生器产生 PRBS 和码型
    • 所有选件都可以从 N4903A 进行改型和升级

    J-BERT N4903B 高性能串行 BERT 为嵌入式时钟设备和正向时钟设备提供最完整的抖动容限测试。

    当研发和验证团队需要对包含 7 Gb/s 或 12.5 Gb/s 串行 I/O 端口的芯片和收发信机模块进行表征和强化测试时,它是最理想的选择。它可以表征接收机的抖动容限,并可检查与当前最流行的串行总线标准的一致性,例如:

    • PCI Express® 查看测量解决方案实例:PCIe 3.0 接收机测试
    • SATA/SAS
    • DisplayPort
    • 超高速 USB
    • 光纤通道
    • QPI
    • 存储器总线,例如全缓冲 DIMM2
    • 背板,例如 CEI
    • 10 GbE/ XAUI
    • XFP/XFI、SFP+
    J-BERT N4903B 的抖动设置屏幕 自动抖动容限表征
    Jitter setup screen of J-BERT N4903B Automated jitter tolerance characterization
    快速眼图和模板测试 RJ/DJ 分离的 BERT 扫描
    Quick eye digram and mask test

    J-BERT N4903B 的主要优势:

    使用具有极低抖动和极短跳变时间的码型发生器生成干净信号,实现精确表征。经过校准的内置抖动源使您可以对接收机进行精确的抖动容限测试。

    J-BERT N4903B 是为与串行总线标准实现最佳匹配而设计的,具有差分 I/O、在大多数输出上可变的电压电平、内置的抖动和 ISI 功能、码型序列发生器、参考时钟输出、可调谐 CDR、码型捕获和比特恢复模式,可对无时钟和不确定的码型进行分析,因此可以显著简化测试设置。

    使用 J-BERT 的自动抖动容限测试和快速总体抖动测量,可以更快地执行测试。

    J-BERT N4903B 是一项长期投资,它可以根据当前的测试和预算要求进行配置,还可以从 N4903A 进行升级,并在以后测试需求变化时对所有的选件和全速器件进行改型。

    PCIe 是 PCI-SIG 的商标,PCI Express 是 PCI-SIG 的注册商标
