100BASE-T1 Automotive Ethernet Protocol Decode Software offers protocol decoding as specified in the 100BASE-T1 Automotive Ethernet specification. PGY-100BASE-T1 Automotive Ethernet Protocol decode software runs in Tektronix Oscilloscope and provides measurements for protocol decode at the click of a button. This allows engineers to quickly check for 100BASE-T1 Automotive Ethernet compliance and flexibility to debug the failure. In addition to this, engineers can decode the command and response of 100BASE-T1 Automotive Ethernet to debug the communication. PGY-100BASE-T1 Automotive Ethernet takes advantage of the digital channels of MSO and provides the decoding of 100BASE-T1 Automotive Ethernet data lines.

Detail View

Users can now feed the output of the directional coupler to Tektronix Oscilloscope for time-domain view. PGY-100BaseT1 protocol decode software runs in Tektronix Oscilloscope, easily decodes PAM3 encoded 100BaseT1 signal. This enables the engineers to quickly understand the protocol activity between the Master and Slave ECU.
