Bit Error Rate Measurement

KEY FEATURES

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
