Tektronix BSX240
Bit Error Rate Tester

BSX240 Key features:

  • Provides a single solution for Receiver stress testing, debug and compliance
  • Test Gen3 and Gen4 standards including PCIe, SAS, and USB3.1 and proprietary standards
  • DUT handshaking capability up to 32 Gb/s supporting RX test requirements for loopback initiation and adaptive link training for key standards such as PCIe and SAS
  • Protocol-aware pattern generation and error detection supports flexible stimulus response programmability and debugging of handshaking issues.
  • Forward error correction (FEC) emulation option supports measurement of BER both before and after error correction for commonly used Reed-Solomon FEC codes.
  • Calibration and test automation software available for key standards
