Welcome
The TBT3/TBT4 Rx application performs the test as per the Gen 2 / Gen 3 USB4 Electrical CTS Revision 1.02.
Welcome
Figure 1: TekRxTest - Thunderbolt4 Gen 2 / Gen 3 Rx application
Key features and benefits
• Calibration and Compliance Testing comes as a part of the receiver solution.
• Automated Calibration procedure is handy along with the ability to reload and rerun older Calibration files.
• Receiver BER, Signal Frequency Variations Training (SFVT), Jitter Tolerance (JTOL), and Sensitivity test for the DUT using the
Electrical Testing Tool (ETT) from USB-IF.
• 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 Thunderbolt3/4 devices at 10, 10.3125, 20 and 20.625 Gbps.
• The solution showcases the eye diagram at TP3’ and TP3 endpoints.
• Reliable and accurate results reduce the test execution time and minimize the skillset required to perform calibration and testing.
• Available tests can be run at TP3’ (Case 1) and TP3 (Case 2) test points and come with crosstalk feature.
• Detailed reports are at one’s disposal for all calibration and test modules.

Operating basics
Operating basics
Launch the application
To launch the TBT3/4 Gen 2 / Gen 3 TekRxTest application, click the shortcut icon TekRxTest on the desktop and select TBT3 or TBT4
Gen 2 / Gen 3 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.
Thunderbolt Receiver Test Application Manual 14
Figure 2: 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.
Operating basics
Launch TekRxService
The TBT3/4 Gen 2 / Gen 3 TekRxTest application interfaces with the oscilloscope for data acquisition, analysis, and data retrieval utilizing
TekRxService application. TekRxService should be launched from the oscilloscope before initiating a connection between the oscilloscope
and TekRxTest application.

TP3' Calibration
The TP3' calibration panel allows you to perform TP3' calibration for Data Rate and save the results.
You must perform TP3' calibration before you start performing the calibration for TP3.
TP3' Calibration Procedure
Click on TP3' under the Calibrations tab to view the previously run calibration reports. At this stage, you can choose the data rate (10 Gbps
or 10.3125 Gbps or 20 Gbps or 20.625 Gbps), the run calibration reports for the selected data rate will be populated in the results table.
When you click on
procedure to perform the calibration.
During this process, the TekRxTest application calibrates the following items:
1. AC-DC Balance: The subsequent calibration modules assume the high and low frequency portions of the waveform to be of equal
amplitude which is accomplished through AC – DC Balance.
2. Eye Height Calibration: A nominal differential amplitude of 700 mV is calibrated to be used in other calibration modules.
3. Preset Calibration: The various predefined Preshoot and De-emphasis levels are required to be calibrated within a tolerance.
4. DDJ Calibration: The preset with the least data dependent jitter is found and used in further modules.
5. ACCM Calibration: The AC Common Mode Interference is required to be calibrated to 100 mVp-p at a frequency of 400 MHz.
6. RJ Calibration: The Random Jitter is to be calibrated to a nominal value of 0.14 UI p-p.
7. PJ Calibration: The periodic jitter at frequencies of 1, 2, 10, 50 and 100 MHz is calibrated to a nominal value of 0.17 UI p-p.
8. TJ Calibration: The Total Jitter at the predefined frequencies of 1, 2, 10, 50 and 100 MHz is calibrated be in the range of 0.3375 –
0.3625 UI p-p (Gen 2 - 10 and 10.3125 Gbps) and 0.355 – 0.405 UI p-p (Gen 3 - 20 and 20.625 Gbps).
9. Input Eye Diagram: In this step of calibration, it is ensured that the signal, with all the calibrated stresses, meets the Eye Height (700
mV for both Gen2 and Gen3) and Eye Width (0.175-0.825 UI for Gen2 and 0.19-0.81 UI for Gen3) requirements for 1, 2, 10, 50 and
100 MHz with the help of a predefined mask, ensuring that there are no mask hits.
