BERT

ML4039B (f)@2x
ML4039B Gen2-BTP

Summary:

The ML4039B is a full feature 200G BERT. It has instrument-grade 2.92mm coaxial connectors and covers a wide range of bitrates between 1.25 and 30 GBaud, while supporting both NRZ and PAM-4 coding schemes.

The GUI makes it possible to individually control each TX level, equalization, eye balance, pattern and Gray coding. The user may also inject error sequences into the stream. The receiver features CTLE and FFE equalization that, in combination with TX FFE, compensates for up to 30 dB of loss at Nyquist. It also allows advanced troubleshooting capabilities by showing separate LSB and MSB BER, offering targeted error-insertion and allowing real-time monitoring of the received signal levels histogram, SNR and receiver equalizer tap values.
