DPO4ENET Ethernet Triggering and Analysis Automated Trigger, Decode, and Search for 10BASE-T and 100BASE-TX Ethernet Designed for use with the MSO/DPO4000B Series Oscilloscopes Data Sheet Peak-to-peak jitter on 100BASE-TX with single voltage crossing. 85/100/115 plots for the 100BASE-TX Return Loss measurement. TDSET3 ­ Automated Ethernet Physical Layer Compliance Testing Ethernet compliance testing has some unique measurement challenges: Generating the "disturbing" signal requires tools to generate both pattern data and noise to provide real-world noise for return loss measurements There are many individual amplitude, timing, return loss, and template tests required for each Ethernet variant: The 10BASE-T standard specifies 22 tests per port plus fault tolerance and CMRR The 100BASE-TX standard outlines 12 tests per port plus CMRR and more The 1000BASE-T standard calls for 80 tests per port plus BER, CMRR, and more Because of the large number of individual tests, compliance testing takes a lot of setup and measurement time, and makes repeatable measurement results difficult to achieve quickly Performing return loss measurements can be expensive if using a vector network analyzer. Tektronix provides a patented, cost-effective method using an arbitrary waveform generator (AWG) and oscilloscope The TDSET3 provides automated compliance testing for 10, 100, and 1000BASE-T PHY verification, including: Compliance and margin testing for accurate analysis and improved interoperability Time- and frequency-domain measurements made with single analysis instrument Jitter and timing measurements with and without filters Amplitude, linearity, and droop testing for transmitter performance Frequency domain measurements including return loss and power spectral density User-defined mode enables flexible parameter control for characterization and margin analysis Detailed test reports with margin and statistical information aid analysis TDSET3 Ethernet Compliance Test Software automates Ethernet physical layer tests for 10BASE-T, 10BASE-Te, 100BASE-TX, and 1000BASE-T in compliance with standards such as IEEE 802. 3-2000 and ANSI X3. 263-1995. The portfolio of tests includes core PMA and MDI tests like Template, Distortion, Return Loss, Jitter (including the proposed alternate jitter method), and Common Mode Voltage. Amplitude Domain Tests The industry standards require the signals to have amplitudes within specified ranges to assure interoperability between devices. [. . . ] The TF-GBE-ATP is the advanced test package which also includes a 1000BASE-T jitter test channel cable. Complete Solution for Receiver Test Tektronix offers a complete solution for creating and managing "disturbing" signals for accurate receiver stress testing. The Tektronix arbitrary waveform generators provide support for adding and removing the noise-related elements of the disturbing signal. Tektronix offers a complete set of instruments for Ethernet compliance tests and debug work; from oscilloscopes and probes, to compliance test software, test fixtures, and signal sources. www. tektronix. com 3 Data Sheet Triggering on a specific 10BASE-T MAC source address. A complete set of triggers, including triggers for specific MAC address, MAC length/type, MAC client data, IPv4 and TCP header content, TCP and IPv4 client data, and FCS errors, ensures you quickly capture your event of interest. Color-coded display of 100BASE-TX, showing preamble, MAC addresses, IP header, TCP header components of the serial signal. DPO4ENET ­ 10BASE-T and 100BASE-TX Triggering and Analysis Debugging Ethernet-based embedded systems designs provides some complex measurement and analysis challenges: Capturing specific Ethernet addresses and data Displaying the elements of the Ethernet message in an understandable format, in a variety of formats, for a wide variety of engineers and technicians Time-correlating Ethernet messages with analog and digital signals in the embedded system Capturing long time windows of Ethernet traffic and then finding specific events within the acquired data The DPO4ENET application module, installed in an MSO/DPO4000B Series oscilloscope, provides a robust set of tools for debugging embedded systems with 10BASE-T and 100BASE-TX Ethernet, including: Automated serial triggering, decode, and search for Ethernet 10BASE-T and 100BASE-TX Triggering on all the critical elements of an Ethernet 10BASE-T and 100BASE-TX such as address, data, etc. Triggering on and decoding IPv4 internet protocol and TCP transport protocol Decoding all the critical elements of each message. Searching through long acquisitions using user-defined criteria to find specific messages Event Table showing decoded serial bus activity in a tabular, time-stamped format for quick summary of system activity 10BASE-T and 100BASE-TX Triggering Trigger on packet content such as start frame delimiter (SFD), MAC addresses, MAC length/type, MAC client data, Q-tag control information, IPv4 and TCP header, TCP and IPv4 client data, end-of-packet, and FCS errors. 10BASE-T and 100BASE-TX Decode The DPO4ENET Ethernet Serial Application Module provides a higher-level, combined view of the individual signals that make up the 10BASE-T or 100BASE-TX bus, making it easy to identify where packets begin and end and identifying subpacket components such as preamble, SFD, MAC addresses, data, FSC, errors, etc. Are you wasting time manually decoding the waveform?Tired of having to visually inspect the waveform to count clocks, determine if each bit is a 1 or a 0, combine bits into bytes, and determine the hex value?Let the MSO4000B or DPO4000B with a DPO4ENET Ethernet Serial Application Module do it for you!Once you've set up a 10BASE-T or 100BASE-TX bus, the MSO4000B or DPO4000B Series will decode each packet on the bus, and display the value in hex, binary, or ASCII in the bus waveform. 4 www. tektronix. com Ethernet 10/100/1000BASE-T Application Software -- TDSET3 · DPO4ENET Characteristics TDSET3 Compliance Test Characteristics General Mask Autofit, Waveform/Sample Count.

Packets are time stamped and listed consecutively with columns for each component (Time, Destination Address, Source Address, Length, Data, FCS/CRC, and Errors). 10BASE-T and 100BASE-TX Search 10BASE-T and 100BASE-TX packet content triggering is very useful for isolating the event of interest, but once you've captured it and need to analyze the surrounding data, what do you do?In the past, users had to manually scroll through the waveform counting and converting bits and looking for what caused the event. With a DPO4ENET Ethernet Serial Application Module, you can enable the MSO4000B or DPO4000B Series oscilloscope to automatically search through the acquired data for user-defined criteria including packet content. Each occurrence is highlighted by a search mark.
