ML4039E-ATE 4-Channel | 58 GBd PAM4 & NRZ | 400G BERT| 4 x 58 GBd NRZ/PAM4 BERT | SSPRQ, PRBS13Q & PRBS31Q | TX and RX Equalizers | Signal SNR and Histogram| The ML4039E-ATE is the ML4039E benchtop instrument designed into a form factor more suitable for ATE. The ATE form factor allows the ML4039E-ATE to better fit inside an ATE loadboard environment or even inside an empty space of the testhead. With the accelerated growth of hyperscale datacenters, the performance demands on Ethernet network infrastructure is increasing exponentially, and customer expectations for high-speed data throughput is at an all-time high. As a result, Bit Error Rate Testers (BERT) have become a cornerstone for physical layer testing, from qualifying bit transmission for 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 ML4039E-ATE is a 4x112 Gbps BERT that supports PAM4 signal generation required for 400G measurements as well as NRZ encoding. It is ideally suited for the validation and production testing of optical transceivers, in addition to functional and signal integrity testing. It supports the required test patterns defined by IEEE and OIF. Other features include signal-to-noise ratio (SNR) and histogram measurements, as well as transmitter and receiver equalizers.

ML4039E-ATE4 x 56 GBd PAM4 BERT Introduction The ML4039E-ATE is a full featured 400G BERT that can be configured as four channels of 56 GBaud PAM4 or 56 Gbps NRZ. Also, half rates of 28 GBd are supported in PAM4 and NRZ modes. The transmitters support all standard test patterns mandated by IEEE and OIF such as PRBS13Q, SSPRQ, PRBS31Q, etc. Additionally, the user may program the TX to output a user-defined pattern. In addition, the ML4039E-ATE supports transmitter and receiver equalization to overcome signal integrity impairments due to channel losses or reflections. • Data Rates: 23-29 & 46-58...
