Electrical TX Test SW for IEEE 802.3 Ethernet (10G/40G/100G NRZ)

데이터 시트

Introduction

Easy-to-use oscilloscope application that lets you: 

• Save time in understanding details of standards 

• Reduce your IEEE 802.3 test times from hours to minutes 

• Debug your device using custom configurations

The greatly increased worldwide demand for video and data transfer has created new requirements for network expansion, driving innovative network elements for operation up to 100 Gb/s. New designs are facing more challenges while transferring these signals on printed circuit boards within hosts and modules, even for short distances. Measuring the IEEE 802.3 parameters can take a full day when manually characterized, and recalculating factors and equation-driven limits adds to the time the designer spends on testing. 

 

Keysight Technologies, Inc. created the following IEEE 802.3 Compliance and Debug Applications to simplify measuring these transmitter parameters and to obtain full results to test limits in a few minutes: 

• N1091APCA Electrical TX Test SW for IEEE 802.3ap/bj (10G-KR and 40G-KR4)

• N1091BMCA Electrical TX Test SW for IEEE 802.3bm (XLAUI, CAUI-4, CAUI-10, and nPPI)

• N1091BACA Electrical TX Test SW for IEEE 802.3ba (40G-CR4 and 100G-CR10)

• N1091BJCA Electrical TX Test SW for IEEE 802.3bj (100G-KR4 and 100G-CR4)

This will keep you focused on getting your products to market knowing that your results are built on the heritage and consistency of Keysight measurement technology.

 

Keysight Electrical TX test SW for IEEE 802.3:-

The Keysight N1091AP/BM/BA/BJCA TX test SW is a measurement application for the DCAX/DCA-M equivalenttime sampling oscilloscope that designed to save you time and money by automating the task of performing NRZ transmitter (TX) test measurements

 

Transform Complexity into Simplicity:-

Satisfying the comprehensive requirements of the IEEE 802.3 clauses can be very complex. The list of tests and test conditions vary from clause to clause, and each can be challenging to properly set up. The tests for each IEEE 802.3 clause vary, as do the test limits. An example of one group of tests from clause 93 is below. The time for your test development team to read and interpret the specification and then implement that understanding into test plans can take several months of effort.

Hosts and modules have unique interface connectors and require compliance boards or test adapters to enable connection to test equipment. Designers endeavor to minimize the trace lengths on the compliance boards and cable lengths.

 

Debug and Verify Your Designs Quickly and Easily

The IEEE Electrical TX test software will control the N1000A/86100D DCA-X, N109X DCA-M, or ENA/PNA/TDR and readily measure your device.
