Bit error rate (BER) is a key performance attribute of digital communications. The BER analyzer can be used to evaluate the quality of the signal transmitted by a network, subsystem or device. It compares the received data stream with the transmitted data stream to calculate the BER number.
The BA-4000 BER analyzer is an NRZ/PAM4 electrical BER analyzer designed for production lines. It is available in six models.
BA-4000-4-28-NRZ: 100G BER analyzer, supporting 4-channel NRZ 28 Gbit/s test.
BA-4000-8-28-NRZ: 200G BER analyzer, supporting 8-channel NRZ 28 Gbit/s test.
BA-4000-4-28-PAM: 100G/200G BER analyzer, supports 4-channel NRZ 28 Gbit/s or 4-channel PAM4 28 GBd test.
BA-4000-4-56-PAM: 200G/400G BER analyzer, supports 4-channel NRZ 56 Gbit/s or 4-channel PAM4 56 GBd test.
BA-4000-8-28-PAM: 200G/400G BER analyzer for 8-channel NRZ 28 Gbit/s or 8-channel PAM4 28 GBd test.
BA-4000-8-56-PAM: 400G/800G BER analyzer for 8-channel NRZ 56 Gbit/s or 8-channel PAM4 56 GBd test.
The BA-4000 BER analyzer provides powerful burst error analysis using FEC simulation functions. Key FEC functions include
PRBS error detection and correction
