Accelerating compliance tests with off-instrument parallel processing
High-speed digital protocol compliance tests for like LPDDR4, USB, DisplayPort, and PCIe5 require executing hundreds of tests involving data acquisition and post-acquisition analysis. Each successive generation adds more tests and more processing requirements, where computation may take significantly longer than data acquisition. The solution to overcome this challenge is to offload the analysis to external compute resources that operate faster and in parallel. This technique is called measurement disaggregation.
Offloading data to external compute resources requires an oscilloscope supporting remote data processing. In this configuration, signal acquisition is done on the instrument, while signal analysis is done on external compute resources. A test sequencer is needed to distribute multiple processing tasks to parallel computing nodes. When properly implemented, this significantly reduces time to results, while preserving typical compliance pass / fail reporting capabilities.
Compliance test acceleration solution
Accelerating compliance test processing requires a solution that can offload computational tasks to high-performance parallel computing resources. The Keysight compliance test acceleration solution offloads computational tasks from the oscilloscope for PCIe5, DisplayPort 1.4a, LPDDR5, and USB4 compliance tests. The compliance test software running on an UXR oscilloscope sends captured data to multiple virtual machines managed by a test sequencer. The Keysight UXR oscilloscope can continuously capture waveforms while offboard server resources analyze and post-process the waveforms in parallel.
The media could not be loaded, either because the server or network failed or because the format is not supported.
This is a description of the Displayport Compliance application running with Keysight's Disaggregation Technology to obtain 2.5-4x test speed gains. This applies to all supported TX compliance applications using the same Automation Framework. This modal can be closed by pressing the Escape key or activating the close button.

How to Accelerate High-Speed Digital Compliance Testing
D9010AGGC Compliance Test Software Measurement Server License
The D9010AGGC compliance test software license provides the capability to offload the measurements from the compliance test software running on an oscilloscope to one or multiple virtual machines or measurement servers. This allows you to perform continuous data acquisition and computation of tests result in parallel, reducing the overall test time.
The M9537A is a second-generation AXIe embedded controller which enables new capabilities such AXIe wide PCIe support, multiple 4K video outputs, and optional high speed disk cache. It is designed for high performance, compact AXIe systems.
