Pattern Generator and Error Detector

The pB100A4 is a bit-error-rate tester that includes a quad 24 to 30 Gbit/s pattern generator and error detector to interface with transceiver evaluation boards enabling customers to test 100G modules.

Ideal to generate and check a variety of bit patterns, the pB100A4 allows for easy adjustment and validation of transceivers. Its high-quality output eyes, attached high-speed I/O cables as well as GUI and API interfaces enable widespread adoption at a very competitive price.


  • High-quality signal generation and accurate, detailed error counting and reporting
  • Windows-compatible GUI and easy integration into an automated testing environment for production using the API interface
  • Most cost-effective unit and smallest form factor in the industry
  • Hardware also supports quad 10G transmission
