Test software allows a close look at Automotive Ethernet: Page 2 of 2

Tektronix has launched two new software packages that greatly simplify Automotive Ethernet testing, debug and Protocol Decode for use with its 5 and 6 Series mixed signal oscilloscopes (MSO).
Tektronix has launched two new software packages that greatly simplify Automotive Ethernet test, debug and Protocol Decode with its 5 and 6 Series mixed signal oscilloscopes (MSO).

The three levels of PAM3 in Automotive Ethernet introduce additional complexity in signaling and place new demands on test methodology, in part because the three amplitudes produce two eyes diagrams. The PAM3 analysis package provides a comprehensive set of measurements with software clock recovery that offer greater insight into signal characteristics, speeding up validation and characterization of PAM3 designs with different cable lengths, noise conditions or ECU configurations. The software also enables eye opening measurements, eye mask testing, jitter separation and Bit Error Rate (BER) plotting in a real ECU environment. 

The PAM3 Analysis along with the Signal Separation softeware have been tested and validated by leading automotive OEMs and T1 companies including Hitachi.

In addition to signal and protocol analysis, the modules also include Automotive Ethernet Physical layer compliance testing as per Open Alliance TC8 specification with full automotive Ethernet test automation and detailed pass/fail reporting.  

Tektronix 5 Series MSO and 6 Series MSO oscilloscopes offer up to 8 GHz analogue bandwidth, 25 GS/s sample rates and a 12-bit analogue to digital converter (ADC) to capture waveforms with the high signal fidelity and resolution needed to view small waveform details in Automotive Ethernet signals.

The Signal Separation (Option 5/6-AUTOEN-SS) and PAM-3 Automotive Ethernet Signal modules are available now worldwide for the 5 and 6 Series mixed signal oscilloscopes.
