Features and benefits
- Comprehensive automated solution for 2.5GBASE-T, 5GBASE-T and 10GBASE-T PHY testing
- One-button selection of multiple tests and four-channel support
- Detailed test reports with margin and statistical information aid analysis
- User-defined mode enables flexible parameter control for characterization and margin analysis
- Efficient test execution on oscilloscopes with instrument remote control
- Single instrument analysis of time- and frequency-domain measurements
- Signal acquisition and analysis support for differential probes or direct SMA cabling
Based on the TekExpress test automation framework, the Ethernet Transmitter Test Application performs all of the PMA electrical measurements as specified by the 802.3an standard, the 802.3bz standard, and the NBASE-T specification. This allows you to quickly and efficiently test Ethernet devices running at 2.5G, 5G, and 10G data rates.
To accurately make these measurements, the Tektronix TF-XGBT test fixture is also needed. The test fixture allows you to reliable and easily access the device under test (DUT) using either differential probes or matched SMA cables.
Power spectral density measurement.
Test selection and instrument setup
Test selection is easy and straight-forward through the intuitive TekExpress workflow. Simply check the measurements you want to perform.
For each measurement selected, the Ethernet Transmitter application will then automatically set up and configure the oscilloscope saving time and ensuring repeatable, reliable results.
As each test is performed, the application will also show you with detailed diagrams how to properly make the needed connections.
A summary report with Pass/Fail status for each test is created after the tests are complete. This report includes test configuration details, waveform plots, and margin analysis to provide more insight into your design.
You can also make changes to test limits and other test parameters in order to do margin analysis to see how well your device is performing.
Droop configuration parameters
Differential single-ended acquisition support
The application allows signal acquisition and analysis with either matched-pair SMA cables or differential probes.
Differential and single-ended support.
The Ethernet Transmitter Test Application simplifies Return Loss testing and eliminates the need for a Vector Network Analyzer by using a patented oscilloscope-based measurement along with a Tektronix AWG. Calibration data for Open, Load, and Short can be stored in a file and recalled.
Complete programming interface
The programmatic interface seamlessly integrates the Ethernet Transmitter Test application with a high-level automation layer such as Visual Basic, MicrosoftNet, C#, C++, Python, or a Web application. This lets you control the state of the TekExpress application running on a local or a remote computer.
Programming examples are found in the application examples folder.
Prerecorded Waveform support will provide customers an option to use prerecorded waveforms when an oscilloscope is not available. This feature allows waveforms to be shared across multiple locations and removes end-user dependency from using scopes all the time.
