Introduction to the Swift AXT Stimulators SwiftAXT (Sweep Interleaved Frequency Domain Testing of Alien X-Talk) technology achieves sequential measurements through control of measurement timing. The Stimulator is a high performance, low cost, palm size frequency generator that doubles as a load termination for use in Alien Crosstalk measurements For cable vendors, it is for the usage in the lab to have better yield in the manufacturing mass test of the 10Gbps cables. For cable installers, it is aimed for the new 10GbE installation and the upgrade of the existing network. The cable vendors need to have a better yield in the 10G cable manufacturing mass test and ideally the test is to be done within a short time, 2 minutes or less per link. To cable installers who perform the new installation in the field, high success rate in the network implementation is crucial and it boosts the work efficiency if the job could be done with short test time. To cable installers who carry out the upgrade of existing network, it is expected to have better yield in the asset upgrade and the task is to be done in short period of test time. The cable installers need to Evaluate a cable and verify its alien cross-talk performance meets requirements for 10GBASE-T. Find out the worst disturbing cable from a group of cables affecting a disturbed cable. Find out the cable that is most vulnerable to Alien Crosstalk. AXT Stimulators will need to be ordered in pairs.
