The N2101B PXIT 10.3125 Gb/s Bit Error Ratio Tester (BERT) consists of a high accuracy clock source, data pattern generator, and error detector. It will automatically perform bit error ratio analysis to characterize the quality of devices at 12 standard internal rates from 155 Mb/s to 8.5 Gb/s. In conjunction with a synthesizer such as the Agilent N2099A, the N2101B BERT can operate at any rate up to 10.3125 Gb/s. To realize the most complete value of the N2101B it can be combined with the other Agilent PXIT family of products such as the N2100B PXIT Digital Communication Analyzer and the N2102B Pattern Generator. Agilent PXIT 10.3125 Gb/s Bit Error Ratio Tester N2101B Data Sheet Functionality Features The user friendly configuration screen. • Single instrument 3-slot wide PXI card containing pattern generation with error detection • Easily combined with DCA, Synthesizer, Pattern Generator or multiple BERT modules in a PXI chassis • Bit Error Rate in three modes - History (GUI only), Continuous, and Time Window • Automatic clock data align • Eye opening measured and/or extrapolated to a defined error rate • Jitter Bathtub display and analysis • Error injection: single error or error rate injection • Significantly smaller than a conventional BERT • Differential data generation and analysis • User selectable data patterns: ▫ PRBS 2n -1, n=7, 9, 11,15, 23, 31 ▫ K28.5, K28.7 and CR Pat • User defined patterns ▫ 2048 bits maximum length ▫ 16 Kbytes if pattern length is integer multiple of 64 • Pattern generation and BER measurements using the internal clock source for the following rates: ▫ 155 Mb/s (OC-3/STM-1) ▫ 622 Mb/s (OC-12/STM-4) ▫ 1.0625 Gb/s (1xFibre Channel) ▫ 1.25 Gb/s (Gigabit Ethernet) ▫ 2.125 Gb/s (2xFibre Channel) ▫ 2.488 Gb/s (OC-48/STM-16) ▫ 2.500 Gb/s (Parallel Optics, PCI-Express) ▫ 3.125 Gb/s (Xaui) ▫ 4.25 Gb/s (4xFibre Channel) ▫ 5.0 Gb/s (Parallel Optics, PCI-Express II) ▫ 6.25 Gb/s (Double XAUI) ▫ 8.5 Gb/s (8xFibre Channel) • Pattern generation and BER measurements using an external clock at any rates from 622 Mb/s up to 10.3125 Gb/s. Therefore the N2101B can generate patterns and perform BER measurements on these standard rates. ▫ 9.95 Gb/s (OC196/STM64) ▫ 10.3125 Gb/s (10 Gigabit Ethernet) 2 Bit Error Rate: History Mode.

To fulfill this a Windows® application and DLL are provided. The Windows application enables the user to control the instrument without any user development required. The DLL provides an API through which custom applications can be easily developed to integrate the BERT. For further ease of programming and compatibility, example code is supplied. In addition to the DLL API, ActiveX Control extends programmability to any ActiveX container or COM compliant programming environment. This includes Visual C++, Visual Basic, C#, Excel, LabView and many other environments. Online assistance: www.agilent.com/find/pxit Software features include: Phone or Fax • • • A DLL providing the functions of the API. An ActiveX Control wrapper for the DLL providing the same functions. A Windows application control panel. The following sample code is also provided: • C++ sample code shows how to use the DLL directly. • Visual Basic sample code shows how to use the ActiveX Control. • C# sample code also shows how to use the ActiveX Control.
