数据中心网络带宽始终面临重大压力。脉冲幅度调制（PAM）属于多电平信令格式，可以帮助数据中心应对这一需求。从 NRZ 过渡到 PAM-4 信令是一种巨大的变化，而不是像 100G 那样渐进的演变，因此给设计和测量提出了许多新的挑战。
Keysight N8827A PAM-4 分析软件可以帮助工程师按照 IEEE 802.3bj 条款 94 规定，应用 Infiniium 实时示波器平台完成精确且快速的 PAM-4 电信号表征，满足 OIF-CEI-56G 和 IEEE 400G 等标准所定义的 PAM 测量需求。此外，N8827A 软件工具还使您可以使用 PAM-4 信令，对连续的重复码型（例如 PRBS7）进行比特误码率（BER）和符号误码率（SER）测试。
