As a result, Bit Error Rate Testers (BERT) have become a cornerstone for physical layer testing, from qualifying fiber optic and copper-wire digital data transmission lines to testing signal integrity. A BERT generates a sequence of bits through a communication channel and the received bits are then compared against the transmitted bits. A Bit Error Ratio (BER) evaluates the full end-to-end performance of a connectivity system and assures communication reliability. The ML4039D is a 200G, 4-channel, 28 GBaud PAM4 & NRZ BERT, ideal for the testing of transceivers.

ML4039D4 x 28 GBd BERTIntroduction The ML4039D is a fully featured 200G BERT that can be configured as 4 channels of 28 GBaud PAM4 or 4 channels of 28 Gbps NRZ. The receivers support FEC emulator (KS4, KR4 and KP4) on both PAM4 and NRZ eye modes and will return the post-FEC BER per channel as well as MSB and LSB BERs within the stream. The receivers also show the eye's Histogram and the channel's SNR over time. The transmitters support all standard test patterns mandated by IEEE and OIF such as PRBS13Q, SSPRQ and PRBS31Q. The user may also program the TX to output a user-defined pattern up to...
