PAM4 Transmitter Analysis

Tektronix - PAM4 Transmitte analysis

PAM4 signal modulation techniques are being adopted in the latest 400 Gigabit Ethernet standards by the IEEE P802.3bs working group for 400G (typically 8 x 52G) electrical and optical interfaces. Compared to traditional NRZ that uses two-level signaling, the four-level scheme used in PAM4 significantly increases signal complexity and places new demands on test methodology, which this PAM4 measurement package supports.

Configuring the oscilloscope for PAM-4 analysis is automatically done by the PAM4 analysis software. Simply, select the data source and clock recovery method and all measurements are automatically computed.
