Welcome
Welcome to the Tektronix 100G-TXE, an Tektronix oscilloscope application
software that addresses 100GBASE-CR4, 100GBASE-KR4, and
CAUI-4 standards of IEEE. These three electrical standards make up the
backbone of the current 100G Ethernet industry, and the TekExpress 100G-TXE
automation test solution facilitates turnkey electrical transmitter validation of
most 100G Ethernet systems today.
The 100G-TXE solution specifically targets Annex 83 of the IEEE 802.3bm
standard as well as sections 92 and 93 of the IEEE 802.3bj specification. These
tools allow quick verification to these IEEE electrical standards, while offering
comprehensive test automation, results margining, data logging, and results
reporting in an advanced testing framework.
TekExpress® 100G-TXE Printable Application Help v
Welcome
Key features of TekExpress 100G-TXE include:
■
100G-TXE offers Transmitter 100GBASE-CR4 time domain transmitter
characterization, tracking Table 92-6 Transmitter characteristics at TP2 from
the IEEE 802.3bj cabled I/O specification. This offers a checklist approach to
performing all jitter, Linear impulse response pulse peak and Signal to Noise
and Distortion Ratio measurements, as well as basic AC parametric and
timing operations.
■
100G-TXE also incorporates 100GBASE-KR4 time domain transmitter
characterization, tracking Table 93-4 Transmitter characteristics at TP0a
from the IEEE 802.3bj backplane specification. While the measurements are
identical to 100GBASE-CR4, the electrical limits for 100GBASE-KR4 are
more stringent.
■
100G-TXE includes a third electrical test suite, for Annex 83 of IEEE
802.3bm, tracking Chip-to-module 100 Gb/s four-lane Attachment Unit
Interface (CAUI-4), Table 83E-1 at TP1a and TP4. The user can characterize
the DUT for Host output and Module output by selecting the required test
points. The CAUI-4 support offers advance CTLE scanning provisions to
find optimal eye opening/width.
