Freya is the latest addition to Valkyrie product line, Xena’s Ethernet Traffic Generation and Analysis (TGA) solution.
Named after the Nordic god of fertility, Freya supports testing of 50G PAM4 / 100G PAM4 / 200G PAM4 / 400G PAM4 / 800G PAM4 using 112Gbps SerDes or 56Gbps SerDes based Ethernet.
Freya uses the latest version of Pulse Amplitude Modulation (PAM4), which doubles the SerDes speed to 112Gbps and the Baud rate to 56GBaud or 56Gbps SerDes and the Baud rate to 28GBaud
Freya is designed for 800G switch, transceiver and PHY design validation & Quality Assurance.
Other features:
There are 4 versions of Freya (see table below). Each version can be used in Xena’s modular 4U ValkyrieBay chassis. Freya 4S modules are also available in Xena’s fixed 1U chassis: the ValkyrieCompact.
The Freya test modules are also used for Xena’s award-winning ANLT test solution – the FreyaCompact ANLT Test Appliance.
All Valkyrie solutions includes user-friendly software to make it quick and easy to perform a multitude of relevant performance, QA, compliancy and functional testing: ValkyrieManager, applications for automated RFC 2544, Y.1564, RFC 2889 and RFC 3918 testing, ValkyrieCLI and ValkyrieTimeSynch.
The Valkyrie platform also includes Odin test modules for testing 10Mbps to 10G using NRZ, Loki test modules for testing 10G to 100G using NRZ, and Thor for testing 10 to 100G using NRZ and 100G to 400G using PAM4.
This technical note explains in detail how Freya tests the link training process to help you optimize the performance of 112G SerDes devices.
It covers: presets, coefficient values and step sizes, link training, Xena’s LT algorithm, how to test the performance of a DUT’s LT, algorithm, FIR filter, the relation between emphasis and tap coefficients, & coefficient settings in Freya.
