Key Features & Specifications

  • Generate and analyze 38 - 45 Gb/s, 10.8Gb/s, 3.35GB/s and 2.7GB/s signals within one system
  • Generate pseudo random word sequences (PRWS) (up to 2.7 Gb/s) and standard PRBS up to 231-1 (up to 45 Gb/s)
  • Analyze bit error ratios (BER) with user-defined PRBS or data
  • Program remotely via Keysight VEE, National Instruments' LabVIEW, Excel, Keysight TestExec, C/C++ and Microsoft® VisualBasic
  • External clock input up to 10.8/21.6 GHz
  • Sub-rate clock outputs at 21.6 GHz, 10.8 GHz, 2.7 GHz/675 MHz (45 Gb/s MUX module only)
  • Clock data recovery (CDR) mode in 45Gb/s DeMUX module
  • Intuitive Windows 2000/ NT® -based user software


The Keysight ParBERT 81250 40 Gb/s solutions are integrated bit error ratio (BER) measurement systems ideal for testing 16:1 and 4:1 OC-768 MUX (multiplexing), DeMUX (de-multiplexing) and serial devices. Depending on the configuration, the system generates and analyzes serial data streams at 38 up to 45 Gb/s, at the associated 1/2, 1/4, 1/8 and 1/16 subranges and parallel data streams at up to 10.8 Gb/s. Generate standard PRBS data up to 2^31-1 and on the parallel lines pseudo random word sequences (PRWS). Analyze BER with user-defined or PRBS data. The system hardware is VXI-based and the user software is Windows 2000 / NT®-based

The Keysight ParBERT 81250 40G electrical/optical Parallel Bit Error Ratio Tester systems are ideal for testing the parallel and serial sides of OC-768 either optical or electrical allowing semiconductor, component and equipment manufacturers to accelerate time to market.
