Prodigy Technovations PGY-100BASET1 Automotive Ethernet Protocol Analyzer provides passive tapping of 100BaseT1 Bus. Powerful layer 2 to layer 7 protocol layer trigger capabilities with flexibility to capture protocol activity over long period of time makes it easy to debug 100BaseT1 designs.
Automotive Ethernet interface scales up to address current and future needs of in-vehicle bus speed requirement. Need for higher speed in-vehicle bus is increasing to support feature-rich ADAS and connected vehicle needs. Two wire full duplex 100BASET1 PAM3 signaling is the choice of interface bus to address these needs. But 100BASET1 bus is difficult to non-intrusively access at physical layer for protocol analysis. Active tapping of 100BaseT1 adds Latency and buffering limitation and may not provide real world timing and protocol layer information to debug the design problems. Oscilloscope based Protocol decode solutions has limitations in buffer size and makes it difficult to use in real world applications due to the low 100BaseT1 bus utilizations.
Prodigy Technovations 100BaseT1 Automotive Ethernet Protocol Analyzer provides industry first solution for non-intrusively passive tap the 100BaseT1 bus at physical layer and ensure no latency and accurate capturing of protocol data. Powerful basic and multi-level layer 2 to layer 7 protocol trigger capabilities enables design engineer capture protocol activity at specific event. PGY-100BaseT1-PA supports continuous streaming of captured protocol data to host computer SSD/HDD enabling long duration capture.

Protocol Analysis
Ethernet is one of the oldest protocol widely used protocol for many applications. Design engineers are used to view and analyze the protocol data in specific format. PGY-100BaseT1-PA Protocol Analyzer software maintains the traditional views and provides advanced analysis capabilities. Live decoding capability provides decoding with any FCS error packets.
Analytics of Protocol data
Analyzing Protocol data to identifying the design issues is a challenging task in millions of protocol packets. PGY-100baseT1-PA provides statistical information about each layer packet count and error packets. This simplifies process of isolating the errors to specific protocol packets or protocol layer. Powerful expression based search capabilities quickly helps in locating packet of interest in the acquired entire protocol data for further analysis.
