Automotive Ethernet Test Solution

1000BASE-T1/100BASE-T1 (Opt. 6-CMAUTOEN/5-CMAUTOEN) Datasheet

1000BASE-T1/100BASE-T1 (Opt. 6-CMAUTOEN/5-CMAUTOEN) Datasheet



Key features

  • Test Time: Fully automated with setup wizard, to perform compliance testing as per the Automotive Ethernet 1000BASE-T1 (802.3bpTM) and 100BASE-T1 (802.3bwTM) standards. The software automatically configures equipments as per test requirement which reduces overall test time.
  • Test Coverage: Automotive Ethernet solution for 100BASE-T1 and 1000BASE-T1 is designed as per IEEE and Open Alliance specification. The Test coverage is as per OPEN Alliance TC8 ECU test.
  • Validation and Debug: Supporting tools, such as advanced jitter analysis, help to catch problems before compliance testing, or in the event of a failure.
  • Signal Qualification: In addition to compliance testing, automated tests and advanced jitter analysis tools are provided for testing your DUT under different environmental conditions.
  • Comprehensive Report: Automated reporting with Pass/Fail screenshot of the waveform.
  • Measurement Accuracy: The 5/6 Series MSO oscilloscope provides accurate and repeatable results with a 12-bit vertical resolution at the sampling rate of 3.125 Gs/s (5 Series MSO) and 12.5 Gs/s (6 Series MSO).
  • Return Loss Measurements: The 100/1000BASE-T1 specification defines Return Loss measurement that requires a Vector Network Analyzer (VNA). A patented measurement approach in the Tektronix Automotive Ethernet Test Solution software allows the designer to perform return loss measurement using an oscilloscope, reducing the need for additional test equipment.
  • ECU Clock Access: The Distortion test requires to access ECU clock which is not possible most of the time. Tektronix unique algorithm software correction method (patent pending) allows user to perform Distortion measurement without connecting clock from ECU. This method is available for 100BASE-T1 and 1000BASE-T1.
  • Performance Verification: Automotive Ethernet application allows user to run Selected test for multiple times. The report shows pass/fail result of each run to study ECU performance over different run.

Automated Automotive Ethernet compliance testing

Physical layer compliance tests have been defined to ensure interoperability between different designs and hardware vendors. These requirements to perform these tests have been expanded and now cover Automotive Ethernet 1000BASE-T1 (802.3bpTM) and 100BASE-T1 (802.3bwTM). For electrical signaling, there are specific tests defined for the Physical Media Attachment (PMA), and as part of Group 1, focuses primarily on the transmitter. The 1000BASE-T1 Automotive Ethernet testing requires an oscilloscope with a minimum of 2 GHz bandwidth.

The Tektronix Automotive Ethernet test solution provides automated compliance testing for 100BASE-T1 (IEEE 802.3bwTM) and 1000BASE-T1 (IEEE 802.3bpTM) requirements. The automated compliance solution includes test software that runs on a 1 GHz or greater Windows 10 OS Tektronix oscilloscope to perform all physical layer (PHY) transmitter compliance tests.

The compliance software allows for complete or selective testing of any of the transmitter electrical specifications, including complete oscilloscope control of the required setups. Software setup flexibility allows you to perform design validation, margin analysis, and repeatable compliance testing while reducing instrument setup difficulties. Additionally, the software can generate a comprehensive date-stamped test report with pass/fail results, and display waveforms and data plots.
