Valkyrie Videos
Stateless traffic generation and analysis up to 800Gbps
At Xena, we agree with a quote attributed to Albert Einstein that if you can’t explain something simply, you don’t understand it well enough. So here’s a short video from Xena explaining how the two Ethernet modulation techniques – NRZ & PAM4 – work and the different between them.

Link Training is a critical part of optimizing the performance of devices running 56G & 112G SerDes Ethernet.
This 90 second video shows how it works and illustrates why its such a key feature of our Freya 112G SerDes test solutions!
Stay tuned for more videos like this from Xena, all dedicated to explaining the complexities of testing high-speed Ethernet in a simple-to-understand way.
1 min 28 secs
Testing at 112G speed is challenging and requires focus especially on layer 1-3. In this video we demonstrate how you can perform a 112G SerDes Auto Negotiation, Link training and TGA test with a Xena solution.
The demo is performed with a mix of internal Xena scripts and ValkyrieManager.
Our demo setup is a Xena Freya module in a Valkyrie chassis connected via a ½ meter electric cable to another 112G SerDes Device Under Test.

In this video we connect to Xena’s live demo system and quickly configure and run a RFC2544 test using Valkyrie2544, which is a free app bundled together with ValkyrieManager.
You can try this yourself right now using Xena’s live demo system.

This video shows how to import a port configuration file (saved as a .txt file) to instantly create several streams of traffic so you can explore Valkyrie’s comprehensive feature set.
You can try this yourself right now using Xena’s live demo system.

Chimera Videos
See how easy Ethernet impairment emulation can be
The ORAN standards recommend using a network impairment emulator to help simulate real-world traffic to test interoperability and performance.
This video shows how quick and easy this can be done using Chimera. First we add 20 microseconds latency to Ethernet traffic between 2 devices using ValkyrieManager.
We then repeat the test using Xena OpenAutomation (XOA), Xena’s open-source test automation platform. XOA features a Python API that makes it simple to integrate Chimera into any existing test automation framework.
5 min. 24 secs
This Chimera video covers:
1. Downloading & installing the Chimera software
2. Connecting to Xena’s live demo system
3. Configuring the Chimera & Loki test modules,
4. Creating traffic streams and mapping the streams to flows, and
5. Adding impairments to the individual flows.
You can try this yourself right now.

This video shows you how to add:
– Constant latency
– Step function
– Uniform jitter
– Gaussian jitter
8 min. 30 secs
Shows you how to use Chimera to limit the bandwidth of Ethernet packet flows passing through a device, using the policers and shapers of the impairment pipeline.
8 min. 31 secs
Shows how Chimera flow filters are used to map incoming packets to up to 8 different flows per port. Each flow can then be independently impaired.

Examples of how to use Xena OpenAutomation
This video shows how to test 112G SerDes Auto Negotiation & Link Training using ValkyrieManager and then Xena OpenAutomation (XOA).
Our demo setup is a Xena Freya module in a Valkyrie chassis connected via a ½ meter electric cable to another 112G SerDes Device Under Test.
