PCIe5.0 (Base) Receiver Test Application Help 13

Welcome

Welcome to the PCIe5.0 (Base) TekRxTest application. This application performs the test as per the Gen 5 Base specification Revision 5.0 Version 1.0.

Figure 1: TekRxTest - PCIe5.0 Base application

Receiver testing is accomplished by connecting the output of BERT PPG (which can produce specific PCIe test patterns) to the input of the DUT through a specialized set of fixtures and cables. The BERT can be programmed to add different amounts of random jitter, sinusoidal jitter, differential, Common mode interference along with variable signal amplitude, preshoot, and de-emphasis. Output of the DUT is connected to the BERT error detector to identify bit errors on the DUT Tx traffic, either during loopback or during sweep of one of the stress parameters. Any error detected can be assumed to be generated from the DUT Tx path as a result of either the DUT experiencing a bad bit-decision at its receiver or uncompensated back channel loss at the error detector of the BERT.

Key features and benefits

• PCIe Gen5 Receiver JTOL Testing as per Base specification for Non-Root complex / Root Complex devices.

• Automated calibration, forced loopback initiation, and testing.

• Jointly with Anritsu BERT MP1900A series, the receiver solution provides the tools and flexibility needed to visualize and control impairments , observe real-time eye performance, etc. for PCIe Gen5 devices.

• Reliable and accurate results reduce the test execution time and minimize the skill-set required to perform calibration and testing.
