Equipped with 2 QSFP-DD cages, this module can test speeds ranging from 10GE NRZ all the way to 400GE using 56G PAM4 SerDes, making it extremely flexible.

The module also provides advanced tool to help developers optimize signal integrity and Bit Error Rate (BER) performance on the tested links.

Z400qx Thor offers extensive L1 test features. With the integrated Xena PHY providing valuable insights into advanced PCS and PMA layer testing including dynamic transceiver clock sweep, lane skewing and PRBS modes. Signals can be analyzed in advanced Signal Integrity View (SIV), to provide visual information on signal quality.

Z400qx Thor can be installed in the Xena B2400 chassis for up to 12 400G ports, or it can be delivered in our Compact chassis, making it a small and lightweight 400G Ethernet test solution.

Z400qx Thor comes complete with XenaManager, the intuitive multi-user management software for generating and analyzing traffic. Also included is Xena OpenAutomation (XOA), an open-source scripting and automation framework designed to help test engineers make the most of Xena testers with tailored tests, and standardized RFC test methodologies.

Ethernet Auto-Negotiation & Link Training Test Tools

Z400qx Thor traffic generators support Auto-Negotiation and Link Training (AN/LT) on 56G SerDes (PAM4).

Z400qx Thor also provides a AN/LT Utility making additional AN/LT tools available for thorough testing of the endpoint behavior during AN and LT process.

The AN/LT Utility adds insight, visibility, and configuration possibilities to the AN and LT process making it easy to analyze DUT behavior during AN/LT, configure and optimize the relevant AN parameters and LT coefficients, on PAM4 signals.
