Anritsu announces all-in-one 400GbE PAM4 BER measurements
Anritsu Corporation has released its 64-Gbaud PAM4 Pulse Pattern Generator (PPG) and 32-Gbaud PAM4 Error Detector (ED). This PAM4 BERT supports 400GbE testing when these modules are installed in the Anritsu Signal Quality Analyzer-R MP1900A series to implement a bit-error-rate test solution with best-in-class signal level quality and excellent Rx sensitivity for next-generation broadband communication systems.

The Signal Quality Analyzer-R MP1900A is a leading bit error rate tester for the over 400G market and supports generation of high-speed signals as well as analysis of signal performance.

The new PPG for PAM4 signals up to 64 Gbaud claims the best Tr/Tf (20% to 80%) time of 8.5 ps (typical) and Intrinsic Jitter of 170 fs (typical). Moreover, the multichannel function can be expanded up to 4 channels, and the integrated Emphasis function corrects signals degraded by transmission path loss. The 32-Gbaud PAM4 ED module has a high sensitivity performance of 23 mV (typical) and supports installation of a clock recovery function required for Rx sensitivity evaluation, as well as PAM4 symbol error measurements.

As a result, the true performance of 400GbE optical modules and devices can now be tested within an adequate margin, satisfying the specifications. This means you can now avoid difficulties in achieving an accurate evaluation due to inadequate signal quality. Additionally, the multichannel expandability helps cut measurement times using simultaneous measurement of multiple lanes. Moreover, easy combination with jitter and noise addition functions to configure an all-in-one test solution for evaluating Rx sensitivity, helps improve development and testing efficiency.
