Tektronix USB4v2 Test Solution

Product overview

USB4 version 2.0 (USB4v2) makes a major upgrade in high-speed interconnect technology, using the foundation of USB4 and Thunderbolt 3/4. It introduces new capabilities, supports data transfer rates up to 120 Gbps while staying compatible with existing USB and Thunderbolt protocols.

The Tektronix USB4v2 Receiver testing software improves the accuracy and precision of USB4 Receiver calibration (TP3') and testing. It simplifies the receiver testing through a step-by-step user interface designed by industry leaders. Our active industry engagement ensures that our software evolves with the technology. The design team focuses on balancing simplicity and user control, to ensure your device can complete correctly calibrated stress tests and perform efficiently with optimized Physical Layer (PHY) settings.

Applications

USB4v2

The key features of the USB4v2 receiver software are:

• Single-click operation to complete both Case 1 and Case 2 calibration routines at TP3'
• Displays summary after key calibration steps
• Removes oscilloscope intrinsic noise for better measurement accuracy
• Performs automated calibration for key steps
• Intelligence to converge target value of Signal to Noise Ratio (SNDR) which is very sensitive to Differential Mode Interference (DMI)
• Generates detailed report with eye diagram
• Resume incomplete calibrations
• Supports Trit Error Ratio (TER) test for both symmetric and asymmetric mode

TP3’ calibration

The TP3’ calibration is mandatory for all devices to meet the required tolerances at the defined reference plane. The Tektronix USB4 Receiver Test Wizard guides the user through all the necessary steps as per the specifications, to ensure future calibration complete smoothly.

TP3’ calibration highlights

• Signal validation and skew correction during equipment initialization
• Single-click option to perform the full TP3' calibration sequence
• Calibrate amplitude, level mismatch, and AC common mode
• Perform Sinusoidal Jitter (SJ) calibration at frequencies 1, 2, 10, 50, and 100 MHz
• Perform Random Jitter (RJ) calibration
• Perform SNDR calibration by adjusting DMI
• Removes oscilloscope intrinsic noise while calculating SNDR
• Validate target value for all calibrations

PJ calibration

• Perform automated Periodic Jitter (PJ) calibration for 1, 2, 10, 50, and 100 MHz
• Generate separate linear response curves for each PJ frequency
• View a detailed calibration summary for each PJ frequency

SNDR calibration

• Perform automated SNDR calibration
• Remove Oscilloscope noise captured during calibration for accurate results

Aggressor Calibration for BER Testing

To simulate near-end crosstalk conditions during Trit Error Ration (TER) testing, perform aggressor calibration.

Aggressor calibration supports the following:

• Case 1 and Case 2 calibration modes
• 1-channel and 2-channel Pulse Pattern Generator (PPG) setups

USB4 receiver tests

• Select TP3' and aggressor calibration files to run Receiver (Rx) tests
• Enable near-end crosstalk simulation across all test scenarios
• Configure the Electrical Test Tool (ETT)
• Run tests manually for greater control and flexibility
• Define custom BER test duration
• View test results in a structured, tabular format
• Display performance margins for each PJ frequency
• Execute tests across all PJ frequencies: 1, 2, 10, 50, and 100 MHz

Results and reports

• Generates a comprehensive report for each calibration, including a summary
• Includes detailed TP3' calibration results alongside receiver (Rx) test data
