Automated software aids PCI Express 3.0 transmitter compliance

An automated compliance test package for PCI Express (PCIe) 3.0 physical-layer transmitter compliance testing from Agilent Technologies Inc. includes measurement support for the laytest PCIe 8-GT/s interface.
 
The PCIe specification defines a high-speed serial bus used primarily for data communication between a computer’s main CPU and high-speed peripheral components such as graphics, networking and storage adapters. It is capable of operating at data rates from 2.5 GT/s to 8 GT/s.

Devices operating at 8 GT/s present measurement challenges that require new tools and procedures for proper validation and jitter margin analysis.

The Agilent N5393C compliance test software for Infiniium 90000 Series oscilloscopes performs a wide range of oscilloscope-based tests for the PCIe 1.x, 2.x, and 3.0 standards. It also provides early 8-GT/s physical layer transmitter measurements for customers designing to the requirements of the PCIe 3.0 specification.
 
The N5393C PCIe compliance test software for Infiniium 90000 series oscilloscopes provides design and validation engineers with a way to verify physical layer transmitter compliance for PCIe 2.5-GT/s, 5-GT/s end point, root complex systems and devices and for 8.0-GT/s chipsets.

The software:

  • provides automated compliance test support for the BASE and CEM measurement points supporting PCIe 1.x and 2.x standards, as well as BASE specification support for the PCIe 3.0 standard;
  • supports de-embedding of test fixtures and cables to help improve voltage and jitter margin measurements when used with the optional Agilent N5465A InfiniiSim waveform transformation toolset;
  • displays the results in a flexible report format; and
  • provides a margin analysis that shows how closely a device passes or fails each test.

Engineers designing and developing PCIe 3.0 devices also can use the Agilent J-BERT N4903B serial BERT for physical-layer receiver compliance testing and characterization. They can use the Agilent DCA-J 86100C TDR system for characterizing PCIe 3.0 channels.
