描述

Keysight 81134A双通道3.35 GHz脉冲码型发生器是是德最新一代高速脉冲码型发生器产品。在定时和性能非常关键的应用环境(例如类似PCI Express和串行ATA的高速串行总线应用),其快速上升时间和低抖动可以精确地检定设备,并使抖动源注入的抖动影响达到最小。与其先一代产品Keysight 8133A类似,新型81134A也为高速应用定义了标准。除此之外,


81134A还可以产生特定的应用信号电平,比如预加重和去加重(PCI Express)或静噪(串行ATA)等。Keysight 81134A可代替脉冲和数据源来帮助您测试被测器件(DUT)。

81134A提供了产生基于硬件的伪随机码(PRBS)和基于存储器的码型生成功能,可定义Infiniband、PCI-Express和串行ATA的基本测试码型。每通道深达12 MB的码型内存可支持需要长数据流的测试,比如磁盘驱动器测试。现在,借助基于PC的新型码型管理工具,81134A可以更轻松地处理长码型。该管理工具可在基于Microsoft Windows的PC上生成、修改和存储码型。此外,它还提供了一种易于使用的功能,允许通过一个远程控制接口GPIB、局域网或USB将所选码型快速加载到81134A中。码型管理工具可从下面的“软件和固件下载”链接中进行下载。


81134A是理想的数据和码型源,尤其适合于眼图测量。其测量辅助设备包括Keysight 54850A串行Infiniium实时示波器和带有抖动分离功能的86100C Infiniium宽带宽DCA-J数字通信分析仪取样示波器。81134A配合这些示波器使用,可提供完整的高速数字激励/响应解决方案。


在使用81134A时,可以人为地把时钟和数据信号进行劣化,其灵活可变的交叉点和抖动注入功能使它成为进行信号完整性测试的理想选择。您可以轻松地改变要注入抖动的频率、大小和形状来模仿实际环境中的信号,例如把Keysight 33220A一类的的任意波形发生器连接到码型发生器的延迟控制输入上,就能实现这样的功能。其图形用户界面可帮助您快速对所有相关参数进行设置,您还可以使用任意一种远程接口(包括GPIB、局域网和USB 2.0)来对81134A实现远程控制。

Keysight / Agilent 81134A Pulse Pattern Generator, 3.35 GHz, Dual-Channel

The Agilent 81134A 3.35 GHz Pulse Pattern Generator provides programmable pulse periods from 15 MHz (66.6 ns) to 3.35 GHz (298.5 ps) on all channels. With frequency ranges this fast, the transition time performance becomes critical; the 81134A performs at less than 60 ps transition. The Delay Control Input and the Variable Crossover Point functionalities allow fast and easy Signal Integrity measurements, including emulation of real world signals by adding jitter to clock or data signals or by distorting the eye for eye diagram measurements.


When timing and performance requirements are critical, for example in high-speed serial bus applications like PCI Express or Serial ATA, it's fast rise times and low intrinsic jitter allow the precise and in-depth characterization of devices, e.g. receivers or backplanes. On top of that, it allows to generate application-specific signal levels like pre- and de-emphasis (PCI Express) or squelch (Serial ATA). The Keysight 81134A lets you test your DUT instead of the pulse or data source!


Features:

  • Frequency range from 15 MHz to 3.35 GHz
  • Two ouput channels
  • Low jitter
  • Fast rise times (20%-80%) < 60 ps
  • Delay modulation (jitter emulation)
  • Variable cross-over point (eye deformation) LVDS applications can be addressed with output levels from 50 mV to 2 V Pre-/de-emphasis and squelch levels for PCI Express and serial ATA
  • LVDS applications can be addressed with output levels from 50 mV to 2 V
  • Pre-/de-emphasis and squelch levels for PCI Express and serial ATA
  • Hardware-based PRBS
  • Memory-based pattern generation
  • Basic test patterns for Infiniband, PCI-Express and Serial ATA
  • Deep 12 MBit pattern memory per channel supports tests that require long data streams like disk drive tests
  • PC-based Pattern Management Tool, easier to handle long patterns: generate, modify and store patterns on a Microsoft Windows based PC and an easy-to-use function to quickly load the selected pattern to the 81134A via one of the remote control interfaces GPIB, LAN or USB
  • Clock and data signals distortion
  • Versatile variable cross-point
  • Jitter insertion capabilities
  • Frequency, level and shape of injected jitter variation emulate real-world signals, e.g. by connecting an arbitrary waveform generator like the Keysight 33220A to the Pulse Pattern Generators delay control input
  • Graphics User Interface: quick access to all relevant parameters
  • Controllable via the interfaces GPIB, LAN and USB 2.0
  • All inputs and outputs are SMA (f) connectors
