Pulse amplitude modulation (PAM)

The 400 Gigabit Ethernet (GE) standards define four-level PAM (PAM4) multilevel signaling as a recommended modulation format to implement serial 400GE data center interfaces. This is an evolution from the two-state NRZ modulation used in 100GE. PAM4 effectively doubles the data rate for a link bandwidth at the expense of reduced signal to noise ratio (SNR).

You require new measurements to characterize impairments that were not an issue in previous NRZ designs. We can help you ensure accurate and repeatable results to accelerate the development of your PAM4 interface components and systems.
