ML4039B 200G BERT

4-Lane BERT | 1.25 – 29 GBd | NRZ & PAM4
  • Low cost, instrument-grade BERT optimized for high-speed data analysis of 100G/200G devices
  • Wide range of bitrate coverage enables PHY testing for Ethernet, HDMI 2, USB 3.1, PCIe, Fiber-Channel and more
  • Ability to tune the bit rate in very fine steps to facilitate finding the locking margin
  • Supports PRBS13Q/15Q/31Q and user- defined patterns.
  • Low power consumption
  • API library, sample code and Python wrapper

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 29 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.
