AT4039D
Summary:
The AT line of products is highly integrated for the Advantest V93000 system and fits right underneath the load board, in the cavity of the test head extender. Due to this, the signal path to the DUT is kept extremely short.
The AT4039D is a fully featured 200G BERT that can be configured as a 4-channel PAM4 28 GBaud or 4-channel NRZ 28 Gbps lanes.
The receivers support FEC decoding (KS4, KR4 and KP4) and will return the post-FEC BER per channel as well as MSB and LSB BERs and SER within the stream. The receivers also show the eye’s histogram and the channel’s SNR over time.
