PCIe5.0 (Base) Receiver Test Application Help 13
Welcome
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.

Getting started
2. Click Downloads. In the Download menu, select DOWNLOAD TYPE as Software and enter PCIe5.0 (Base) 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 PCIe5.0 (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
Operating basics
Launch the application
To launch the PCIe5.0 (Base) test application, double click the shortcut icon TekRxTest on the desktop and select PCIe5.0 (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.

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.
Operating basics
Launch TekRxService
The PCIe5.0 (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.
