Welcome

Welcome to the PCIe4.0 (CEM) TekRxTest application. PCI Express Architecture PHY Test Specification Revision 5.0 and Version1.0.

Figure 1: TekRxTest - PCIe4.0 CEM 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. Additionally, DUT Tx traffic can be analyzed to verify the DUT responses to various requests put forward by the BERT during link training process.

Key features and benefits

• Automated Calibration, Link Training, and Compliance Testing.

• Receiver JTOL test for AIC / System DUT.

• Jointly with Anritsu BERT MP1900A series, the receiver solution provides the tools and flexibility required to visualize and control the impairments, observe real-time eye performance for PCIe Gen4 devices.

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

Installing the software

Complete the following steps to download and install the latest PCIe4.0 (CEM) TekRx test application.

1. Go to www.tek.com.

2. Click Downloads. In the Download menu, select DOWNLOAD TYPE as Software and enter PCIe4.0 (CEM) in the MODEL OR KEYWORD field and click SEARCH.

3. Select the latest version of the software and follow the instructions to download.

4. Copy the executable file into the instrument you wish to install the software (Real-time oscilloscope or PC).

5. Follow the installation instruction that is available in the website. The software is installed at C:\Program

Files\Tektronix\BERTScope\RxTest60

6. Double click the shortcut icon on the desktop to launch the application.

Note:

• The PCIe4.0 (CEM) TekRx test application can be installed on a Tektronix real-time oscilloscope or a PC (optional).

• You must install the TekRxService and SigTest application in the real-time oscilloscope to successfully connect the application with the real-time oscilloscope.

Operating basics

Launch the application

To launch the PCIe4.0 (CEM) test application, double click the shortcut icon TekRxTest on the desktop and select PCIe4.0 (CEM) in the application window.

Close the application

To exit the application, click on the application title bar. Follow on-screen instructions to save the unsaved session or test setup.

Using other methods to exit the application may result in abnormal termination of the application.

Note:

Launch Real-Time Oscilloscope

The TekVISA Socket Server application on the oscilloscope provides the necessary connectivity between the TekRxTest application and scope. Although it is launched in the background when the scope boots up and the socket is initialized for communication, it is recommended to verify the status by clicking on the Desktop Tray ―› TekVISA LAN Server Control as shown in the image below. If it is ready to exchange data, then a wizard would appear as in the below image.
