Welcome

Welcome to the PCIe4.0 (Base) TekRxTest application. This application performs the test as per the Gen 4 Base specification Revision 5.0 Version 1.0

Figure 1: TekRxTest - PCIe4.0 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 Gen4 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 Gen4 devices.

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

PCIe4.0 (Base) Receiver Test Application Help 15

Getting started

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

Note:

• The PCIe4.0 (Base) 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 (Base) test application, double click the shortcut icon TekRxTest on the desktop and select PCIe4.0 (Base) in the application window.

Figure 2: TekRxTest 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.

Operating basics

Figure 3: Launch Real-Time Oscilloscope

Note: In the unlikely event when the socket is not initialized, the process can be started by clicking on “Start Socket Server” which gets enabled during such a scenario.

Launch TekRxService

The PCIe4.0 (Base) TekRxTest application interfaces with the oscilloscope for data acquisition, analysis and data retrieval utilizing TekRxService application. This software module should be launched at the time of initiating the TekRxTest application.

Operating basics

Figure 4: TekRxService application window

TekRxService has to be launched if the application is being run on an external PC. To launch the application, double click

Note:

the TekRxService batch file shortcut icon in the desktop of the real-time oscilloscope.

The PCIe4.0 (Base) TekRxTest application calibrates the following at TP1 :

1. Amplitude - The differential voltage swing is required to be within 720 - 800 mV. This is done only after the transition and non-transition bit levels are made equal using de-emphasis.

2. Tx Equalization Presets - The various levels of de-emphasis and preshoot are required to be calibrated within the tolerance as specified.

3. RJ - It is calibrated to be 1 ps (RMS value).

4. SJ - The SJ is calibrated over the desired range of 5-10 ps (pk-pk) including the nominal SJ specification of 0.1 UI (6.25 ps) at 100

MHz frequency).

5. SJ @ 210 MHz - If the stressed eye calibration requires sinusoidal jitter levels greater than 0.1 UI, then SJ@210 MHz is used during JTOL test.

6. Multi-tone - It is calibrated over a specific range for multiple user-defined frequencies.
