速率模式：8x100G，4x200G，2x400G，1x800GbE
制式：112Gb/S PAM4
遵循规范：IEEE802.3CK
功能支持：
RS-FEC性能评估，Pre-FEC，Post-FEC，Symbol Error distribution
Auto-Negotiation，Link Training自协议和链路学习测试与分析
可独立使用，进行AN/LT过程的仿真与互操作测试，并记录交互过程的细节，可通过改变仪表参数来验证800G 112Gb/S DUT在不同AN/LT参数情况下的匹配情况
可使用验证AN/LT，也可以AN/LT与L23 Traffic结合验证，测试完整的L1/2/3层的性能，Traffic Tx/Rx等指标
