Complete suite of bit analyzers for R&D and manufacturing up to 800G
The BA-4000 is a world-class series of 100G/800G electrical bit-error-rate (BER) testers. It is designed for the production line, quality control and R&D use from components to transceivers and cables.
The BA-4000-RCNC model has been specifically designed to enable the testing of linear-drive pluggable optics (LPO), a technology addressing the need of high bandwidth and low power interconnects required by AI/ML applications. The strong correlation between the BA-4000-RCNC test results and real switch performance reduces uncertainty, allowing manufacturers to qualify transceivers with confidence and efficiency.

Discover the FEC capability on BA-4000
Bit error rate (BER) is the major indicator of the performance of transceivers and transmission systems based on PAM4 modulation. Discover all the advanced FEC features available on the BA-4000.
Powerful equalizer and channel simulator designed for LPO testing
With LPO transceivers, no DSP is present to precondition or equalize the electrical signal, as is done in retimed optics. Therefore, any change in signal integrity on the host side is reflected onto the optical side and the more times the signal is handed off, the more potential for introduction of bit errors. Traditional transceiver testing techniques can’t pick up this signal degradation so new, more powerful testing techniques are required. The BA-4000-RCNC detects the presence of reflection, intersymbol interference (ISI) and FEC tail instability which are key performance indicators, capturing the presence of errors. Learn more.

Description
Bit error rate (BER) is a key performance attribute for digital communications. The signal transmission quality of a network, subsystem or component, can be evaluated using a BER tester, which compares the data stream received to the transmitted sequence and computes the number of errors.
The BA-4000 Bit Analyzer is an electrical NRZ/PAM4 BER tester designed for the production floor. It comes in six models:
- BA-4000-4-28-NRZ: 100G BERT including 4-channel NRZ 28 Gbit/s.
- BA-4000-8-28-NRZ: 200G BERT including 8-channel NRZ 28 Gbit/s.
- BA-4000-4-28-PAM: 100G/200G BERT enabling either 4-channel NRZ 28 Gbit/s or 4-channel PAM4 28 GBd.
- BA-4000-4-56-PAM: 200G/400G BERT enabling either 4-channel NRZ 56 Gbit/s or 4-channel PAM4 56 GBd.
- BA-4000-8-28-PAM: 200G/400G BERT suitable for either 8-channel NRZ 28 Gbit/s or 8-channel PAM4 28 GBd.
- BA-4000-8-56-PAM: 400G/800G BERT suitable for either 8-channel NRZ 56 Gbit/s or 8-channel PAM4 56 GBd.
The BA-4000 Bit Analyzer leverages FEC simulation capabilities to provide powerful analysis for burst error. Some of the main FEC features are:
- PRBS error check and correction
- Pre-FEC and Post-FEC BER
- KP4/KR4 and low latency FEC protocols
- FEC Generator and Checker (FGC) to address RS-FEC Scrambled Idle Pattern
- FEC symbol error distribution plot: codewords vs symbols errors
- FEC margin auto-calculation
