Software Options


Automotive Ethernet enables faster data communication to meet the demands of today’s vehicles and the connected vehicles of the future. QPHY-10Base-T1S automates testing and validation of 10 Mb/s Automotive Ethernet, which is described in 10Base-T1S (IEEE 802.3cg) specification.

MDI Return Loss and Mode Conversion tests also available with QPHY-10Base-T1-TDR.

Automated Compliance Testing

QPHY-10Base-T1S performs electrical compliance testing of the Physical Media Attachment (PMA) according to the 10Base-T1 specifications. Detailed connection diagrams ensure the proper setup and provide information about the required test pattern for each test. Upon completion of the test session, results are automatically compiled into a comprehensive report including screenshots.

Flexible Debug Environment

Using the “Stop on Test” feature, the user can pause testing after each individual test and observe the results. At that point, any of the oscilloscope’s tools can be leveraged for further debug and upon completion, testing can be seamlessly resumed with a click of a button.

Transmitter Output Voltage

The output voltage is calculated by measure the peak-to peak voltage on the Test Mode 1 waveform.

Transmitter Timing Jitter

The trasmitter master timing jitter timing is tested while in DUT is in Test Mode 1. TIE is measured and the range of the TIE values are used to calculate the peak-to-peak TIE jitter.

Transmitter Output Droop

The output droop is calculated on both the positive and megative symbols in the Test Mode 2 waveform. The magnitude of the droop is measured with respect to an initial peak value after the zero crossing (indicated by Max and Min parameters) and the value 800 ns after the initial peak value.

Transmitter PSD

The Power Spectrum Density (PSD) of the transmitter is tested against the specified limits defined by the mask while the DUT is transmitting Test Mode 3. Using the oscilloscope for the PSD test removes the need to purchase a spectrum analyzer.
