Download Datasheet
software

The Z800q Freya Ethernet traffic generator can test 800GE, 400GE, 200GE, 100GE and 50GE using 112G/56G SerDes PAM4

A versatile solution for performance and functional testing of Ethernet network infrastructure and equipment including switches, routers and NICs, the Z800q Freya can test up to 800GE using 112G SerDes (PAM4 112G) and is designed for helping achieve the best possible signal integrity and Bit Error Rate performance.

The Z800q offers extensive L1 test features for 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, which provides visual information on the quality of the signal.

The Z800q Freya test module also supports Auto-Negotiation and Link Training (AN/LT) on 112G SerDes and 56G SerDes.

Z800q Freya modules can be installed in the modular XenaBay B2400 chassis (where they require 3 slots), or in the fixed XenaCompact chassis, making it the most compact and lightweight 800G Ethernet test solution in the market.

XenaManager is included, giving users access to an intuitive user-friendly multi-user management software where they can generate and analyze traffic. Xena OpenAutomation (XOA) enables customers to make the most of Xena testers with tailored tests as well as standardized test methodologies, to achieve accelerated release cycles, enhanced test reliability, and boosted customer satisfaction.

Ethernet Auto-Negotiation & Link Training Test Tools
Freya customers can purchase Freya 800 AN/LT SW Lic license for enabling AN/LT Utility on Z800q Freya and Z800q Freya-OSFP modules. This license enables additional AN/LT tools for thorough testing of the endpoint behavior during the auto-negotiation and link training process.

The AN/LT Utility provides 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.
