[. . . ] Ethernet Compliance Test Software TDSET3 Data Sheet Applications 10BASE-T Ethernet 10BASE-Te Ethernet 100BASE-TX Ethernet 1000BASE-T Ethernet Tektronix offers comprehensive, integrated tool sets for validating the physical layer of IEEE 802. 3 Ethernet devices, and for developing and debugging Ethernet-based systems. The Tektronix TDSET3 Ethernet Compliance Test Software and selected Tektronix oscilloscopes provide one-button testing for 10/100/1000BASE-T test suites as specified by the IEEE standard for compliance testing. TDSET3 automates compliance testing and allows engineers to perform the required tests efficiently and reliably right on their bench. Features & Benefits Automated Compliance Testing for 10/100/1000BASE-T PHY Verification Designed for use with DPO7000 and MSO/DSA/DPO70000 Series Oscilloscopes Data Sheet 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 specification 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. [. . . ] These tests include timing measurements such as rise time, fall time, and difference or symmetry between rise and fall times. Jitter Tests Jitter tests quantify the timing variations of the edges of the signal, using specified test patterns. These jitter measurements include the contributions from duty-cycle distortion and the baseline wander. Jitter is determined by accumulating waveforms, measuring the width of the accumulated points at the eye crossing, and the peak-to-peak is inferred from minimum and maximum values in the tails of the histogram. For example, the figure above shows the jitter measurement on a 100BASE-TX signal. TF-GBE-EE Test Fixture for Energy Efficient Ethernet measurements on 10BASE-Te. Template Tests Template mask tests are often used to quickly verify that the transmitted signal meets industry standard requirements. These template masks are defined so that signal distortions such as overshoot, jitter, incorrect rise and fall times, etc. , will cause the mask test to fail. An example of a 10BASE-T template mask test is shown above. Test Fixtures The TF-GBE Series of test fixtures supports many of the Ethernet compliance tests, providing convenient signal access, test points for accurate removal of disturbing signals, return loss calibration, and cross-connect circuits to connect to traffic generators and link partners. The TF-GBE-ATP is the advanced test package which also includes a 1000BASE-T jitter test channel cable. The TF-GBE-EE is an additional test fixture which is required to perform the Energy Efficient Ethernet measurements. Simplified Pattern Generation Tektronix offers a complete solution for creating and managing "disturbing" signals for accurate 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. Test Report Generation The unparalleled automation built into TDSET3 also enables faster validation including the tedious task of generating reports. The user can generate summary or detailed reports at a press of a button. www. tektronix. com 3 Data Sheet Characteristics General Characteristic Description Ordering Information TDSET3 Ethernet Compliance Test Software.
