Bit Error Rate Measurement
  • Measures actual bit errors while a known PRBS-11 pseudo-random test sequence is being transmitted
  • Accurate BER measurement downto 10-8
  • Adjustable measurement window from 1,000 bits to 1,000,000,000 bits, to trade off BER range and measurement duration
  • Fast automatic synchronization (n-PSK phase ambiguity removal)
  • Cycle slips detection
  • 32-bit cumulative BER counter for long-duration measurements
  • Built-in PRBS-11 test sequence generator for end-to-end BER measurements
  • 1 bit serial / 2 bit parallel input selection (I before Q, or I/Q)

  • ComScope–enabled: key internal signals can be captured in real-time and displayed on a host computer
